Whether running, climbing, hiking, backpacking, camping, or doing just about anything, really, a trusty bright headlamp is indispensable when you’re outdoors after dark.
Finding a good light among the sea of cheap, unreliable ones can be tough, though. We reviewed 33 of the best headlamps and spent 200+ nights testing them to find headlamps that are bright, reliable, comfortable, and easy-to-use.
To find the best headlamp, we looked at lumen output, battery life, water resistance, and price, and we only included headlamps with reliable supply chains, responsive customer service, and positive user reviews. These are the best headlamps for different types of outdoors activities and why we think they deserve those titles.

The 6 Best Headlamps
THE BEST HEADLAMP: BIOLITE HEADLAMP 425
Power Source: USB Rechargeable Lithium-Ion battery (USB-C)
Run Time (High): 4 hours
Run Time (Low): 60 hours
Weight (including batteries): 2.75 ounces
Maximum Beam Distance: 85 meters
Waterproof Rating: IPX4
Price: $60
What we like: Comfort, fit, brightness, battery life, weight
What we don’t like: update is bulkier than previous model, locking mechanism is more finicky than previous version
The Biolite 425 is the updated version of the Biolite 330 that we adored in previous versions of this story. The new Biolite 425 now uses a USB-C rechargeable battery, which solves our one complaint about the previous model. As a result, the battery life is even longer–20 more hours at the low setting and 30 more minutes at the high setting. Something we don't like quite as much, though, is the battery pack in the back is a little bigger, adding about .3 oz to the overall weight. After more than a year of testing and missing our old headlamp, we've come around on the 425, which is why we award it Best Headlamp overall. Here's why we think it's still the best headlamp option for most outdoors folks.

While we appreciate the improving tech when it comes to rechargeable headlamps, we are a little disappointed by the change in fit and comfort that accompanies the bigger battery pack. 0.3 oz extra may not sound like a lot, but the increased weight has been noticeable to our testers who have spent a lot of time in the Biolite 330 prior to testing the 425. The Biolite 425 is still a comfortable fit for backpacking and running, just not quite as comfortable as the older version.
Despite our testers’ laments at missing the previous sleek and lighter design, the 425 is a great update for most folks. With 425 lumens, this headlamp is brighter and has a longer lasting battery than the previous model. While we don't always love having a bigger rear light, we know that it's safer for runners, people out walking their dog, and most folks who go outdoors at night.

LIGHTING AND BRIGHTNESS
The BioLite 425 has one white spot LED, one white flood LED, two red flood LEDs, and four white power level indicator LEDs. As with our Best Headlamp for Battery Life, the Black Diamond Spot 400, we think these are the essential lighting features that every good headlamp should have.
Our testers have found the BioLite’s 425 lumens were more than bright enough to night hike safely, seldom using the maximum brightness setting. In fact, we didn't need to use the brightest light setting, even while hiking at night.
Both the spot and floodlight modes are dimmable. One nice feature is that the light does a quick double flash when the dimmable light reaches its maximum or minimum power.

BATTERIES AND BATTERY LIFE
The biggest advantage of a rechargeable headlamp is not purchasing a new, disposable battery every few months. Disposable batteries, when thrown into the garbage, take centuries to biodegrade. They also require you to carry extra weight or plan ahead to have batteries on hand before a day hike.
The BioLite 425 has 4 hours of battery life at full power and 60 hours at low power. During months of using the headlamp every night, the battery never died, even when used for night hiking for several hours, setting up, and breaking up camp every day (except when we had issues with the lock function). As a practice, our testers would top off the BioLite’s power at night with a portable battery.

One update we love is that the BioLite 425 is charged with a USB-C rather than a micro-USB cable. This can be plugged into the battery pack on the back of the headlamp band. We like that you don’t have to remove the battery to charge it, unlike the Petzl Actik Core, our recommended Best for Camping winner or the Nitecore UT 27 520 that we tested. We found it easy to pop off the protective case on the BioLite 425 and insert the USB charger.
A few features we really like about the BioLite: it has a battery indicator light and a lock to prevent accidentally turning it on. When you hold the lock down for 8 seconds, it will flash a few times to indicate that it is locked. However, we had some issues getting the lock function to work as well as in the previous model. Three separate testers found the headlamp to unlock itself at various times. We recommend paying special attention to where you store your headlamp.
We also like that you can charge the Biolite 330 while in use. Fortunately, our testers never had to charge the LED headlamp at the same time that he was hiking, but they did take advantage of the charging feature while in their tents at night.
COMFORT AND FIT
Comfort and fit are the BioLite 425’s standout features. The light is integrated into the moisture-wicking band, and the battery is located on the back of the band. This gives it a more balanced weight than the other headlamps we considered, making it suited for hours of use at night as well as running.
While the 425 is less comfy than the 330, we still think this is one of the best fitting headlamps and highly recommend it to backpackers and runners in particular.
WEIGHT
The balanced weight distribution helps the BioLite feel very secure — a reason why it’s a popular running headlamp. The light is easily tilted. The back is heavier than the 330 model, but it’s still a fairly well-balanced and well-fitting headlamp. Runners seem to be impressed by its 2.75 oz weight–that's light for a running headlamp that delivers this much brightness. Backpackers (ourselves included) think it runs on the heavier side, which is why we recommend a our Ultralight winner, for weight conscious outdoors people.
CONTROL BUTTON
The BioLite has a single control button. The button is used to turn on/off or lock the headlamp, scroll through the five light modes, and control the dimmer. Our one complaint about the BioLite is that the button is small and difficult to use while wearing gloves.
We found the BioLite to be intuitive—especially compared to the other headlamps we’ve tested, like the Black Diamond Storm 400. The exception for us is the locking system (hold the gray button down for 8 seconds). As with all headlamps, we suggest reading the instructions and practicing this before taking it out.
WATER RESISTANCE
The BioLite 425 has an IPX4 water resistance rating. This means that it is protected from water splashes in any direction. However, we would have preferred a higher water resistance rating like our longest running headlamp winner, the Black Diamond Spot 400, which is waterproof.
Nonetheless, the BioLite 425 survived the rigors of a variety of adverse conditions our testers put the headlamp through. We night hiked in the rain several times without any issue. We also didn’t take any precautions to protect it from the rain (like put it in a Ziplock bag for extra protection). However, keep in mind that we’ve tested the BioLite extensively in the West. If you’re night hiking on the Appalachian Trail, you may want to consider the Black Diamond Spot 400 instead.
The BioLite 425’s comfort, ease of use, battery life, and brightness all make it a stellar hiking headlamp and an excellent way to convert from AAA batteries to a more eco-friendly gear option. While we miss the 330, we think for most folks–from runners to hikers to people walking the dog–the 425 headlamp should be all you need.
Longest Lasting Headlamp: Black Diamond Spot 400
Power Source: 3 AAA batteries
Run Time (High): 4 hours
Run Time (Low): 180 hours
Weight (including batteries): 2.7 ounces
Maximum Beam Distance: 100 meters
Waterproof Rating: IPX8
Price: $45
What we like: battery life, waterproofness, price, reliability, intuitive buttons
What we don’t like: not as light weight as rechargeables
The Black Diamond Spot 400 is the latest iteration of Black Diamond’s much-lauded Spot series. The Spot excels at all the key metrics: brightness, waterproofness, functionality, and especially battery life — all at a reasonable price. The Spot 400 is tied with the more expensive Black Diamond Storm 400 for most battery life (200 hours on low) of the headlamps we considered. But the Spot 400 is less expensive and lighter weight as well as more comfortable and easier to use. That’s why it wins our award for Longest Lasting Headlamp.

SPOT 400 vs SPOT 350
In our last review of headlamps, the Spot 350 won our overall winner for the best headlamp (and before that, the Spot 325 and Spot 300 was our overall winner!).
The new Spot 400 is almost the same as the Spot 350 in terms of price, weight, settings, weight (2.7 oz vs. 3.0 oz), and battery life. The main difference was that the Spot 400 is some weight savings and 50 lumens brighter—without sacrificing battery life. The Spot 400 max beam is also 20 m farther than the Spot 350.
The Spot 400 is is lighter weight (2.7 oz vs. 3.0 oz) with a more ergonomically designed headband and lightweight plastic casing than the Spot 350. The Spot 400 is also available in more colors. It has the same ease of use and intuitive button system as the Spot 350. It improves an already great headlamp, most notably with brightness and weight savings.
BATTERY LIFE
The Black Diamond Spot 400 uses 3 AAA batteries for 4 hours of run time on maximum power and 200 hours on low power. That matches the longest battery life of any headlamp we considered, including the Black Diamond Storm 400, which runs on 4 AAA batteries instead of 3. A three-battery setup has become the standard for battery-run headlamps, but we like that with the Spot 400, those 3 AAA will give you a lot more battery life than some of the other models we considered.
Liz Thomas finished a multi-year section hike of the Pacific Crest Trail using the Black Diamond Spot 400.
The Spot 400 also matches in battery life the Black Diamond Revolt 350 and Princeton Tec Apex Extreme. Both of those headlamps also have 200 hours of battery life, but both are more expensive with the Apex more than double the price of the Spot.
To keep track of your battery life, there is a six-setting battery meter. In addition, there is a lock feature to prevent the headlamp from being accidentally turned on. The lock feature is a must-have, in our opinion. We’ve had too many accidents with headlamps turning on after jostling in our backpack only to have their battery drained. The battery meter is a nice feature to plan replacements as needed, especially when using headlamps on a thru-hike.

LIGHTNESS AND BRIGHTNESS
The Black Diamond Spot 400 comes with spot, flood, red light, and strobe mode. Spotlight is great for seeing objects in the distance, preferably during nighttime outdoor activities. The floodlight is best for close work, like organizing gear or cooking. The red night-vision mode is best for preserving your night vision and is much more considerate for others in your camp at night. There is also a strobe light mode for emergencies.
The Spot 400 has a thinner, more slip-proof headband and lighter weight case than previous models. Photo courtesy Liz Thomas.
While some headlamps, like our previous Upgrade Winner (the Black Diamond Storm 400), have more modes, we’ve found too many lighting options get confusing. When there are over 7, it’s more gimmicky than useful.
The Spot has just the right balance of functional features that you’ll actually use.
The Spot 400 has 400 lumens of power, up from 350 lumens in the previous model. The LED headlight is dimmable, a very useful feature that allows you to customize the amount of light necessary. At maximum brightness in spotlight mode, the Spot 400’s light can reach 100 meters—up 20 m from the last model.
The Black Diamond Spot also has a “PowerTap” feature. You can instantly switch from full and dimmed power by pressing a button on the right side of the headlamp. This is a helpful feature to quickly boost the light to check out the sound of rustling brush in the distance.
Another nice feature is a brightness memory. The headlamp will return to the previous brightness setting when turned on.
FIT AND FEATURES
Black Diamond redesigned the Spot 400 with a lower profile and a more ergonomic design than some previous Spot models. The thinner band and lighterweight plastic housing are noticeable improvements after hours of night hiking and using headlamps in camp.
As a result, we’ve found the 400 has a more comfortable and stable fit when running or hiking than old models. In addition, the Spot 400 is slightly lighter than earlier Spot models (2.7 oz vs 3.0 oz on the Spot 350). This means even after hours of night hiking, we barely felt the weight of the headlamp.

We really like that you can detach this LED headlamp from the band. This allows the headlamp to be attached to the webbing of backpacks, harnesses, or waistbelts, which is an excellent feature for people who prefer wearing a headlamp lower on their bodies to reduce shadow.
We think a locking feature is an essential element on a headlamp, and the Black Diamond 400 locking system is the most intuitive of the headlamps we considered. There’s a lock icon on the side of the headlamp that you hold down for several seconds to prevent the headlamp from turning on when you don’t want it on. This allows you to save battery when your headlamp is jostling in your backpack.
WATER RESISTANCE
The Black Diamond Spot 400 has an IPX8 waterproof rating. This means that it is designed to withstand water submersion of up to three feet for 30 minutes. However, we recommend caution regarding this waterproof rating.
Black Diamond states that water may enter the battery compartment if the headlamp is submerged, and it should be completely dried out if used in wet conditions. Still, we think this rating is good enough that you can wear it while night hiking in the rain.
The Black Diamond Spot 400 is an excellent all-around headlamp. It provides great light, is well constructed, and is reasonably priced. This conclusion is backed up by Wirecutter, the Big Outside, and by the overwhelmingly positive reviews on REI and Amazon’s websites.
The Best ultralight headlamp: nitecore nu 25
Power Source: USB Rechargeable Lithium-Ion battery (micro USB)
Run Time (High): 0.5 hours
Run Time (Low): 160 hours
Weight (including batteries): 0.99 ounces
Maximum Beam Distance: 81 meters
Waterproof Rating: IP66
Price: $37
What we like: Weight, price, brightness
What we don’t like: not USB-C
The Nitecore NU 25 has been a favorite headlamp of thru-hikers, alpine climbers, ultralight backpackers, and fast and light adventurers due to its 1 oz weight and reliability. After Treeline writers spent a year testing the Nitecore NU 25 on the PCT, camping trips, and guiding ultralight backpacking trips in the Sierra, we agree that the Nitecore NU 25 is the Best Ultralight Headlamp. This lightweight, rechargeable headlamp has all the features we want from a headlamp at an impressive 1-oz weight and more affordable price.
NITECORE NU25
LIGHTING AND BRIGHTNESS
The Nitecore NU 25 has an impressive 360 lumen maximum beam output–among the highest of the headlamps we tested. It has four brightness levels and three special modes (red caution, SOS, and beacon). It comes equipped with three lights: white, red, and high CRI that can throw light 81 m, similar to what other brands call "flood lighting." This max beam distance is better than the other recharagables we tested, including the 75 m of the BioLite 330.
Related: The Best Camping Lanterns
The Nitecore NU 25 has three lights: a high CRI light, red light, and white light.
Given the ultralight weight of the Nitecore NU 25, we were impressed that its lighting mode options are fairly comparable to heavier lights we tested like the BioLite 330 and Spot 400.
Switching between lighting modes on the Nitecore NU 25 is straightforward. For example, the red light is activated with a button with "R" on it. Unlike other headlamps, there aren't so many lighting modes that it becomes confusing.
The Nitecore NU 25 headlamp (far right) in red light mode compared to the Black Diamond Spot (left) and Spot Rechargeable (middle).
BATTERY LIFE
The Nitecore NU 25 is a rechargeable headlamp that runs off micro USB. The included built-in 610mAh li-ion battery is about a third the weight of three AAA batteries, which is how the Nitecore NU 25 works as an ultralight headlamp. The battery life–especially if using the high output mode–requires a more dedicated routine of charging than the BioLite 330.
As an ultralight headlamp, we didn't expect the battery life to be on the same level as headlamps with batteries that are three times the weight.
Still, our one issue with the Nitecore NU 25 is battery life. When using the max light output of 360 lumens, it only lasts 0.5 hour–which is the lowest time of the headlamps we tested. However, in low light mode, it runs for 160 hours, which is better than some other rechargeable headlamps, like the BioLite 330. Still, it’s lower but in the general ballpark of AAA battery headlamps like the Spot 400.
While 0.5 hours at high output Turbo mode isn't as long as we'd like, it's enough to turn on for short sections when you encounter more technical terrain. For example, when night hiking on the PCT, we'd turn the Turbo mode at confusing intersections or rocky and steep areas. Then, when the trail became easy to navigate, we'd return to the less energy-intensive white mode.
As with the BioLite 330, we wish that the Nitecore NU 25 charged via USB-C instead of micro USB so we could have a faster charge.
WATER AND DUST RESISTANCE
The Nitecore NU 25 is one of the only headlamps we tested that has a certification for dust resistance. This is great news for people who like to cowboy camp and are more likely to put their headlamps in the dirt (vs. folks who camp in tents).
The NiteCore NU 25 has an IP66 rating for dust and water resistance. The Nitecore NU 25 has a IPX6 water resistance rating, which means it is protected against high power jets of water. This means that it is generally good enough to use while hiking in the rain. However, it cannot be submerged.
Most of the other headlamps we tested didn't have certifications for dust resistance, so we appreciated that the Nitecore NU 25 is fully protected against dust–at least when the flap is securely over the micro-USB panel.
FIT AND FEATURES
A favorite feature of the Nitecore NU 25 is that it is available in bright yellow. We've lost enough headlamps over the years to recognize how the color of the plastic casing can be an important decision when choosing a headlamp. When we pack up a campsite in the dark, we sweep our campsite to make sure we didn't leave anything behind. A bright yellow gear item is rarely left behind.

The Nitecore NU 25 in Turbo mode is excellent for navigating confusing intersections of trail at night or finding a campsite.
The adjustable headband on the Nitecore NU 25 is surprisingly thick for an ultralight headlamp. This adds to the security of staying on your head.
Given that the plastic casing that holds the lighting and battery unit are so lightweight, the Nitecore NU 25 never gave us a headache. There's so little weight to bounce, that it doesn't bounce during runs, either.
The Nitecore NU 25 is a good option if you are a climber, thru-hiker, or ultralight backpacker looking to minimize gear weight. It's also a good option if you want to spend less on a headlamp than the Black Diamond Spot 400, but want higher performance than our budget headlamp recommendation. Whether you’re fast and light, ultralight, or just looking for a quality rechargeable headlamp, we highly recommend the Nitecore NU 25.
BEST CAMPING HEADLAMP: PETZL ACTIK CORE
Power Source: 3 AAA or Petzl CORE lithium rechargeable batteries
Run Time (High): 2 hours
Run Time (Low): 130 hours
Weight (including batteries): 2.8 ounces
Maximum Beam Distance: 90 meters
Water Resistance: IPX4
Price: $70
What we like: ease of use, reliability
What we don’t like: price
The Petzl Actik Core headlamp is our Best Headlamp for Camping because it is an excellent choice for people who want to save on batteries or be more environmentally conscious without abandoning a battery-powered headlamp. The Actik Core is a hybrid headlamp that can run on AAA batteries or rechargeable Petzl CORE lithium batteries. With this hybrid rechargeable headlamp, you can have the benefits of a rechargeable battery with the security of a battery backup. This is ideal for camping because many people bring extra batteries on camping trips.
PETZL ACTIK CORE
LIGHTING AND BRIGHTNESS
The Actik Core is a favorite in our Best Eco-friendly Gear Swaps to Reduce Your Environmental Footprint and an excellent option for folks who want both the security of backup batteries and the environmental-friendliness of a rechargeable headlamp. Our climbing writer Jocelyn Crawford has used the Actik Core for more than a year, recharging it for climbing trips and to be prepared for situations where she’d need to rappel in the dark.

The rechargeable CORE battery that comes with the Actik Core is a USB-rechargeable lithium battery that fits in the battery compartment. The CORE battery can be removed and replaced. This means if you carry an extra battery, you don’t have to worry about pass-through charging. You can charge one battery at night while using this Petzl headlamp with the other battery inside. It’s the convenience of AAA batteries without the weight or waste.
Related: The Best Portable Solar Panels
The Petzl Actik Core has 450 lumens of light output — among the brightest headlamp we considered. It also has among the farthest beam distance, at 90 meters. At medium power, it has 100 lumens, and low power is 6 lumens. Unlike the other headlamps we considered, it has a mixed beam (flood+spot) for distance vision and a flood beam for better proximity vision. Both beams have several brightness modes. In addition, there is a red light mode to help prevent loss of night vision and inconveniencing others. Finally, it has a red strobe light visible at 700 meters for up to 400 hours.
BATTERY LIFE
The Petzl Actik Core has 2 hours of battery life at max power (450 lumens), 8 hours at standard power (100 lumens), and 130 hours at low power (6 lumens).
The battery life estimate is for the 3 AAA batteries. The replaceable CORE battery pack has the following battery life: 1.3 hours at max power, 10 hours at standard power, and 120 hours at low power. We were disappointed that for both battery modes, the life is still shorter than on our longest lasting headlamp winner, the Black Diamond Spot 400. However, if you want to have hybrid battery capability, this is among the better battery lives available.
If headlamp battery life is a concern for you, like our other hiking headlamp winners, the Petzl Actik Core has a battery life indicator. Plus, the Actik Core has a lock to prevent accidentally turning it on.
The CORE battery pack is charged via a micro USB cable that plugs directly into the battery (no adapter required). It takes three hours to charge the CORE battery fully. Unfortunately, you have to open the Actick Core battery compartment to charge the CORE battery. This means you can’t have the headlamp on while it’s charging. In contrast, our overall winner, the BioLite 425 can be charged by plugging a USB-C cord directly into the battery compartment, meaning it can charge and run simultaneously.

RECHARGEABLE BATTERY VS. STANDARD BATTERIES
The Petzl CORE battery is recharged via USB.
When turned on, the brightness of the rechargeable battery and AAA batteries is the same. However, with the rechargeable battery, the brightness is generally constant during the burn time. This is a perk compared to standard batteries, where the brightness gradually decreases as the batteries are drained.
Self-discharge (the gradual loss of battery life even when the batteries are not in use) is low in the CORE rechargeable battery; it is negligible in standard batteries.
Petzl recommends that you recharge the CORE battery at least every six months. For this reason, rechargeable headlamps may not be the best option to leave in your day pack or keep in a drawer at home for emergency preparedness. So if you’re looking for a headlamp for just-in-case scenarios, we recommend our budget winning Petzl headlamp, the Petzl Tikinna, which runs on AAA batteries.
FIT AND FEATURES
The Petzl Actik Core has a simple, easy-to-use single button to change the lighting mode. It has a detachable, reflective headband that can be washed. Petzl also sells accessories to mount the headlamp to helmets or handlebars for people who don’t want separate Mountain Bike Lights. Ultimately, we think that dedicated bike lights are safer for the rider and for visibility, but sometimes, it’s nice to have a headlamp as backup.
WATER RESISTANCE
This Petzl headlamp has an IPX4 rating. This means that it is protected from water splashes in any direction. We prefer the IPX8 rating on the Black Diamond Spot 400, but this matches the waterproof rating on the BioLite 330.
The Actik Core is a powerful LED headlamp that can hold its own against almost all the other USB rechargeables and battery-run headlamps on the market. Its dual-battery capabilities make it more expensive than our other winners. Still, we think the Actik Core is a great option for folks wanting to reduce the cost and waste of batteries but want the option of a battery backup.

Best Headlamp for running and Trail Running: BioLite 800 Pro
Power Source: Rechargeable Li-ion via Micro-USB
Run Time (High): 7 hours
Run Time (Low): 150 hours
Weight (including batteries): 5.3 oz
Maximum Beam Distance: 130 m
Price: $100
What we like: Comfort, fit, brightness
What we don’t like: price, weight
The BioLite HeadLamp 800 Pro is the brightest rechargeable headlamp and the Best High Lumen headlamp we considered. It’s ideal for activities like running in the dark, mountaineering, big wall rock climbs, alpine starts, all-night ultramarathons, or off-trail adventures.
Unlike other super bright headlamps, it doesn’t need have an extra strap going over the top of the head, meaning it works well for people with pony tails, big hairstyles, or those wearing hats or hoods.
The battery is in the back more comfortable illuminated running and a non-bounce system keeps the light more focused on where you need to go. While this light isn’t for every situation, the BioLite 800 is a well-thought out light for outdoors people who need a lot of lumens for high-demand outdoor adventures.
BIOLITE 800 Pro
LIGHTING AND BRIGHTNESS
At 800 lumens, it's the brightest headlamp among our winners. It's more than twice as bright as our overall winner, the BioLite 425.
At full power (it’s also dimmable), it reminds us more of a car headlight than a typical headlamp. Its longest beam is 130 meters (426.5 feet), the longest of any headlamp we tested.
This makes the BioLite 800 a good choice for situations when you want to see far out, be aware of your surroundings, or have others be aware of your presence.

BATTERY LIFE
The BioLite 800’s 3000mAh battery lasts 150 hours on low and 7 hours on high — the longest of any headlamp we tested. But unlike many other headlamps (especially in the “high lumen” category), it can also be charged via an external battery while in use. The robust, back-oriented battery makes it heavier than other headlamps we tested, but it’s still relatively lightweight for headlamps in the High Lumen category. Like the BioLite 330, it has pass-through charging. So in the unlikely event that your headlamp stops running in the middle of your ultramarathon or climbing trip, you can charge it while still letting it light the way.
LIGHTING MODES
As bright as the BioLite 800 can get, we appreciate that it is dimmable. It also has other lighting and power modes, including rear red lights for visibility. However, with so many features and modes, there are a lot of controls to learn. If it's been a while since you last used this headlamp, you will probably have to dig out the instruction manual to figure out how to use it. Of course, those features also add a price and weight penalty, so if you don’t need those features, you may be better suited by one of our other recommendations.
FIT AND FEATURES
Although we got the BioLite 800 for mountaineering, our Portland-based writer keeps turning to it instead of other headlamps for chores like checking on the backyard chickens every night. The depth of light make it easy to tell whether all the chickens made it to roost and to inspect for eggs that otherwise may be hard to see in the dark. Photo courtesy Kate Hoch.
Aside from the car headlight-like brightness, the most innovative feature of the 800 is the constant run mode feature. The BioLite 800 also has a rear red visibility light, which has made it popular with runners. For mountaineers or ultramarathon runners, the rear visibility light can help keep track of where your climbing partner (or competition) is. It also adds an extra level of visibility for those running roads in the dark. The constant run mode means that both the front brightest headlight and the dimmer backlight can run simultaneously.
Like the BioLite 330, the 800 has a four-point tilt. We found this tilt useful for angling the headlamp, but some media reviewers found it a fault.
Treeline writer Kate Hoch has used its predecessor, the BioLite 750, for the past year climbing and mountaineering in the Cascades and Pacific Northwest, including Mt. Shasta. For these kinds of trips, being able to see farther out is essential for smart route-finding decisions. In addition, many ultramarathoners enjoy trail running with a brighter headlamp, especially when they are likely to hallucinate or become sleep-deprived enough to see things in the dark.
Another runner-friendly feature of the BioLite 800 is the flat, sleek design. Like the 330, it is designed to be flat to the head to minimize headaches and bounce while running. The 800’s battery is larger than the 330, but it’s in the back of the head. As a result, the weight between the front and back is more balanced than other headlamps.
The BioLite’s also more expensive than many other headlamps, but it is moderately priced for a headlamp of this many lumens. So we think the weight and price are worth it if you need a bright headlamp and increased visibility.
THE BEST BUDGET HEADLAMP: Petzl Tikinna
Power Source: 3 AAA or Petzl CORE lithium rechargeable batteries
Run Time (High): 2 hours
Run Time (Low): 120 hours
Weight (including batteries): 2.9 ounces
Maximum Beam Distance: 60 meters
Water Resistance: IPX4
Price: $20
What we like: price, reliability for the price
What we don’t like: lacks the features of more expensive headlamps, especially battery life
The Petzl Tikinna is a solid, basic camping headlamp at a very reasonable cost. Petzl upgraded the Tikkina model in 2019, boosting its lumen output and reducing its weight. It lacks many of the features of our other winners but is a great option for sitting around the campfire, carrying in your day pack (just in case), or keeping in an emergency preparedness kit.
PETZL TIKINNA
LIGHTING AND BRIGHTNESS
In 2019, Petzl boosted the Tikkina’s lumens from 150 to 250. There are three lighting levels. Unfortunately, the Petzl Tikkina only provides a floodlight mode. Floodlight mode is great for sitting around camp or sorting gear in your tent after dark. However, it isn’t as good as a spotlight mode for seeing distances, an essential feature for night hiking or running.
Our other winners have a spotlight mode, and we would recommend our other winners if you are planning to be more active while using your headlamp. The beam distance is the shortest of our winners, at 60 meters.
BATTERY LIFE
The Tikkina has 2 hours of battery life at max power (250 lumens), 9 hours of battery life at standard power (100 lumens), and 120 hours of battery life at low power (6 lumens). This is less than most of the other headlamps we considered, which is to be expected given the budget cost of the Tikkina. Still, it’s competitive with other headlamps in this price range and is good enough for casual use.
The Tikkina uses 3 AAA batteries. However, it does support the CORE rechargeable battery. This is the rechargeable battery used in the Petzl Actik Core, our Best Headlamp for Camping winner. The CORE battery is an optional accessory.
Please note: self-discharge (the gradual loss of battery life even when the batteries are not in use) is low in the CORE rechargeable battery; it is negligible in standard batteries. Therefore, Petzl recommends that you recharge the CORE battery at least every six months. For this reason, rechargeable headlamps may not be the best option to leave in your day pack or keep in a home drawer for emergency preparedness.

The Contenders | Short-List
We researched and tested dozens of headlamp models to find our winners. Here are some headlamps we considered:
BLACK DIAMOND SPOT 400 R-RECHARGEABLE
Power Source: 1500 mAH Li-on rechargeable battery (micro-USB)
Run Time (High): 4 hours
Run Time (Low): 225 hours
Weight (including batteries): 2.58 oz
Maximum Beam Distance: 100 meters
Waterproof Rating: IP67
Price: $65
What we like: battery life, waterproofness, intuitive buttons
What we don’t like: less reliable with no dual-fuel option, cost
As fans of the Black Diamond Spot 400, the new 400 R-Rechargeable option is a great addition to the headlamp lineup. This model–which maintains most of the same specs as the Spot 400 but with a micro-USB-chargeable battery–could be a good option for folks who don’t want to mess with changing batteries.
We think some people will appreciate this model over the Biolite 425, especially those who aren't a fan of the back battery on the Biolite. We very nearly gave the Spot 400 R-Rechargeable our overall award for its impressive battery life and waterproof rating. But as more countries around the world phase out the micro-USB, we prefer the USB-C charging on the Biolite 425. We look forward to when the Spot Rechargable is updated to USB-C.
BLACK DIAMOND SPOT 400 R RECHARGEABLE
This headlamp lasts a whopping 225 hours on low and 4 hours on high. It’s long lasting and weighs a little less than the non-rechargeable headlamp. These updates are great, though ultimately we still appreciate the non-rechargeable Spot 400 for its dual-fuel reliability in the backcountry.
One downside to this model is that it is slightly less reliable than the non-rechargeable model since it doesn’t have the dual-fuel option to switch to regular batteries. Some folks like the comfort of an additional power source option in the backcountry. However, for most folks, the long-lasting battery life of this model is enough.
It’s also worth noting this model costs $15 more than Spot 400, and is slightly less waterproof (though the difference seems to be negligible for most testers).
Ultimately, we appreciate that Black Diamond created this option while still making the regular Spot 400 available. We look forward to continuing to test this model and will keep an open mind to the changing tech.
Power Source: 4 AAA batteries
Run Time (High): 5 hours
Run Time (Low): 200 hours
Weight (including batteries): 4.25 oz
Maximum Beam Distance: 100 m
Water Resistance: IP67
Price: $50
The updated version of a former Best Upgrade Headlamp Winner, the Black Diamond Storm 400 is a dustproof and waterproof headlamp, 400 lumens, and has the longest battery life of the headlamps we considered.
Despite some streamlining in this new model, the Black Diamond Storm 400 is still heavy (it took 4 AAA batteries), and that weight gave us a headache after hours of use. In addition, although PowerTap technology and Brightness Memory features make toggling between settings easier than in earlier Storm models, Amazon and REI reviewers (and our testers) still found moving between advanced lighting modes difficult.
BLACK DIAMOND STORM 400

We prefer the sleeker design and intuitive control panels of the Black Diamond Spot 400 or our overall winner, the Biolite 425. However, we have to admit that this headlamp is much brighter — which is why it is popular with ultramarathoners and trail runners who need to see a lot of detail on the ground.
Still, when the new Black Diamond Storm 400 came out, it had stiff competition with our winner for Brightest Headlamp, the BioLite 800 Pro. The 800 is almost twice as bright. And while the battery life between the two is similar, the BioLite 800 still sneaks ahead by 2 hours in Max mode and 50 hours in low mode.
Related: The Best Shoes for Trail Running
Power Source: Hybrid (USB-C or rechargeable batteries)
Run Time (High): 2 hours
Run Time (Low): 24 hours
Weight (including batteries): 8.4 oz
Maximum Beam Distance: 289 m
Water Resistance: IP66
Price: $120
The Fenix HP25R V2.0 is the brightest headlamp we considered and the brightest rechargeable headlamp on the market.
With 1,600 lumens of brightness, more than twice any of most of our winners, it's a favorite in the running community. The Spotlight can get up to 1600 lumens at 951 feet for 2 hours.
However, it is also the heaviest headlamp we considered at 8.4 ounces. It's also the most expensive. We think our Bright Headlamp winner, the BioLite 800 Pro, gives you plenty of brightness at a more reasonable price. The BioLite 800 also weighs less and balances the weight on the head better than the HP25R. We also like that the BioLite 800 has a light on the front and back, which helps with visibility when running in the dark.
FENIX HP25R V2.0
Power Source: Hybrid (rechargeable Li-On with USB-C or 3 AAA batteries)
Run Time (High): not stated on Turbo, 6 hours on 400 lumen
Run Time (Low): 13 hours
Weight (including batteries): 2.6 oz
Maximum Beam Distance: 102 m
Water Resistance: IP66
Price: $55
The Nitecore UT27 520 is a hybrid headlamp that runs on both AAA batteries as well as a rechargeable lithium battery, similar to the Petzl Actik Core.
Unfortunately, during testing, after only a few weeks of use on backpacking trips, the hinge that opens the battery panel broke so we could not secure the panel. We contacted Nitecore and were able to get a replacement. Unfortunately, that replacement had the similar design flaw in the hinge. This hinge secures the batteries, keeps the headlamp together, and keeps out water.
While we were otherwise intrigued by the dual charging potential of the Nitecore UT27 520, we can't recommend it due to the design flaw in its casing.

Why you need a headlamp for your outdoor adventures
You may know that a headlamp is one of the Ten Essentials–a piece of gear you should bring with you on every outdoor adventure. If you were to find yourself stuck outdoors at night, a headlamp can bring a lot of safety. Here are some other advantages of using a headlamp in outdoor settings:
Hands-free lighting
One of the most significant benefits of a headlamp is that it provides hands-free illumination. This is a huge benefit over a flashlight. This allows you to perform various tasks, such as cooking in camp, reading maps, setting up camp, or even hiking or climbing, without the need to hold a flashlight.
Enhanced safety
Headlamps make you visible to others when you're out after dark. This can be beneficial if your group is separated or for safety when encountering others. This is useful whether you're hiking, running, cycling, or camping. This visibility enhances your safety, reducing the risk of accidents and ensures others can see you in low-light conditions.
Precise illumination
Most of the headlamps we recommend offer focused and directional lighting, which is handy for illuminating specific areas or objects like your cook pot or where you think that mouse hiding under your tent may be. You can adjust the angle and intensity of the light to suit your needs, whether you're examining gear, reading, or navigating uneven terrain.
Improved night vision
A headlamp with a red light or dimming feature helps preserve your night vision. This is particularly useful for stargazing, wildlife observation, or maintaining your awareness of your surroundings without blinding yourself or others with a bright white light. Plus, many folks find it is easier to fall asleep at night if they've been using a red light instead of a bright white one.
Extended adventures
With long-lasting batteries or the option to use rechargeable ones, a headlamp means that you don't have to just be out for a few hours or a day—you'll have a reliable source of light for extended outdoor adventures, including multi-day hikes, or camping trips.
Emergency preparedness
A headlamp is a crucial part of your emergency kit. In unforeseen situations, such as getting lost, encountering injuries, or if gear fails, a headlamp can provide vital illumination and help you move more quickly, signal to rescue teams, and improve morale.
Versatility
Headlamps are useful for all sorts of outdoor activities, including hiking, backpacking, trail running, fishing, biking, and camping. Their adaptability makes them something that ever outdoors person should own.
Camping comfort
A lot of campers and backpackers say that when they're in their tent, a headlamp creates a cozy and well-lit spot for reading, organizing gear, or having some downtime. It eliminates the need for bulky lanterns or flashlights–though sometimes those a great, too.
Nighttime adventures
For those who enjoy nighttime adventures like night hiking or wildlife photography, a headlamp is arguably the most important gear item.
There's a reason that headlamps are on the Ten Essentials list. Not only are they a convenient and safe way to light up your space, they also help keep you safe by alerting others where you are.Whether you're on trail, setting up camp, or going for a stroll after dark, having a reliable headlamp ensures you can see clearly and make better decisions while navigating, making your outdoor experiences more enjoyable.

WHAT TO LOOK FOR IN A HEADLAMP
Headlamps are a hands-free way of lighting your way through the dark. Headlamps create enough light so that you can run, walk, read, or do camp chores. But they also need to stay put on your head and be comfortable while you’re in motion.
In addition, the battery power should last long enough so you won’t need to fumble for replacements in the dark, and replacing batteries or toggling between settings should be equally hassle-free.
BRIGHTNESS
Don’t be fooled by the marketing terms. Brightness is essential in a headlamp, but there are many ways to measure that brightness. Light is usually measured in lumens, but a higher lumen rating doesn’t always mean a brighter-looking lamp. Why? The distance your headlamp can throw light is impacted by reflectors and lenses inside.
Related: Best Wireless Headphones
We’ve found that the headlamp that throws light the farthest distance isn’t always the best for every activity. For example, Gadget Review estimates the distance needed for casual hiking to be 150 feet, where trail running is 30 feet, hunting is 350 feet, and caving/mountaineering is 400 feet. (We were skeptical of the 30 feet, but after interviewing several trail runners, most said having a very bright light immediately in front of them for foot placement choices was more important than distance).
Often, headlamps with the most beam distance require more juice from batteries. Most headlamp companies will tell you lumens and distance in their specs. However, brand-reported numbers may be faulty. See our graph representing distance for more information on distance thrown.
BATTERY LIFE — ANSI FL1 STANDARD
All of our headlamp picks from Black Diamond, Petzl, and BioLite are tested in conformance with the ANSI FL1 Standard. This voluntary testing and specification standard was developed to create a uniform “apple for apple” standard to evaluate portable lighting products. You will see the ANSI FL1 icon on the packaging of headlamp products.
The following is how ANSI performance measures are defined:
LUMEN (LIGHT OUTPUT)
A lumen is a measurement of light output. Before 2012, the light output was typically measured in watts; however, the introduction of the LED light meant power was no longer the primary consideration. As a result, lumens became the standard for measuring light output.
RUNTIME
Runtime is the amount of time rounded to the nearest quarter-hour until output falls below 10%.
BEAM DISTANCE
Beam distance is the distance from the light where the illuminance is equivalent to a full moon on a clear night.
PEAK BEAM INTENSITY
Peak intensity is the measurement of luminous intensity in the middle of the light beam.
It’s important to remember that battery life is inversely proportional to brightness. The brighter the light, the shorter the battery life. So, don’t operate your headlamp at max power unless you really need the extra light or beam distance. It is also essential not to use “dimmable” headlamps brighter than necessary. You'll find dimming features in our longest lasting headlamp winner, the Black Diamond Spot 400, and our overall winner, the BioLite 425.

BATTERY TYPES
Choosing the right headlamp is made more confusing by battery options. Below we review the differences between rechargeable batteries and standard disposable batteries. We also discuss alkaline versus disposable lithium batteries.
Related: Essential Backpacking Accessories
RECHARGEABLE BATTERY VS. STANDARD (DISPOSABLE) BATTERIES
When turned on, the brightness of the rechargeable battery (such as the CORE battery used in our Best Headlamp for Camping Winner, the Petzl Actik Core) and standard AAA batteries is the same.
However, the brightness is generally constant during the burn time with the rechargeable battery, while with standard batteries, the brightness gradually decreases as the batteries are drained. The following graph from Petzl shows the typical battery burn characteristics of rechargeable batteries and traditional batteries.
Rechargeable batteries are more prone to self-discharge (the gradual loss of battery power even when the batteries are not in use) than standard batteries. For this reason, rechargeable headlamps may not be the best option to leave in your day pack or keep in a home drawer for emergency preparedness.
SINGLE-USE ALKALINE BATTERIES VS LITHIUM BATTERIES
A lithium battery generally costs about twice as much as an alkaline battery. But does the longer life of a lithium battery justify the cost? My Broadband, a tech website based out of South Africa, ran a test of an Energizer Max AA battery versus an Energizer Ultimate Lithium AA battery using a CBA IV battery tester.
Their analysis found that lithium batteries had, on average, over eight times the battery life.
Lithium batteries have several other advantages over alkaline batteries:
Lithium batteries are about 30% lighter than alkaline batteries — an important feature for lightweight backpackers or runners or climbers looking to keep their pack weight down;
Lithium batteries have around twice the shelf-life (10 to 15 years vs. 5 to 7 for alkaline batteries); and
Lithium batteries perform better at extreme temperatures (below zero or over 100 degrees)

FLOOD AND SPOTLIGHT MODES
A headlight’s beam pattern is critical, depending on how you intend to use the headlamp. Floodlights produce a wide, uniform light that is good for close-range light. We like to use the floodlight mode when in camp.
A spotlight mode produces a focused, long-range beam. This is better for night hiking or running.
Most budget headlights, like our budget winner, the Petzl Tikkina, only produce a floodlight.
Our other top winners also provide both flood and spotlight modes.

RED LIGHT MODE
The red light mode helps preserve your night vision. This is why red light is used in photography dark rooms and on Navy submarines. It is also very considerate to use red light mode around your fellow campers, so you don’t blind them with a bright white headlamp light. All of our winners, except our budget winner the Petzl Tikinna has a red LED light.
One thing to note about red light mode is that it does impact map reading in the dark. When in red light mode, red markings on maps won’t show up. If your map marks trails in red, you may need to switch to white light to see it. Some headlamps, like our former upgrade winner, the Black Diamond Storm, have green and blue modes to aid in reading maps with colored lines. But we found with the Storm that too many colors and too many lights is more confusing and hard-to-use, and professional and everyday reviewers agreed. That’s one reason we ultimately dropped the Storm from our winners.

TILT ADJUSTMENT
Tilt adjustment allows you to move the headlamp up or down to change where the light focuses. This angle adjustment makes it easier to switch between when you are hiking straight ahead or when you are reading or cooking in camp. A tilt has enough hinge to stay put where you want it, but won’t get stuck, either. All the headlamps we considered have a tilt adjustment, although it is often a feature not found on cheap headlamps.
QUALITY OF LIGHT
Optical quality means how uniform the light looks across the entire beam range. We were cautious about reviews that mentioned floodlights with dark spots in the middle. We also noted when reviewers mentioned bands or hotspots of brighter light in flood mode.
EASY TO TOGGLE BETWEEN SETTINGS
REI and Amazon headlamp users’ biggest complaint about headlamps, in general, is getting the light setting you want. Headlamps usually have a distance mode, proximity (spot) mode, and red mode. Toggling between each light mode should be easy. All of our recommended headlamps have easy-to-use and easy-to-navigate button settings that provide the light you need without creating confusion. Still, we recommend that you read the instructions and practice before using any headlamp in the backcountry.
LOCK MODE TO PREVENT BATTERY DRAINAGE
Lock mode prevents the chance that your headlamp turns on by mistake. We think the lock mode is essential in situations (like a backpacking trip) where you will need a usable headlamp. Without lock mode, it is a common problem for headlamps to turn on in your pack and for hikers to discover a dead battery when the headlamp is needed.
A headlamp should feel comfortable and secure on your head. Treeline writer Amanda Jameson shows what that looks like on a trail in Golden, Colorado. Photo by John Carr.
COMFORTABLE AND SECURE ON YOUR HEAD
It’s crucial that the headlamp feels comfortable when worn. It also needs to be secure on your head, even when you are running or looking down. It should stretch to fit your head and shouldn’t slip. Ideally, you should forget you’re wearing a headlamp.
Comfort is one reason we like our overall winner, the BioLite 425. It has the weight of its battery system in the back of the headlamp instead of upfront with the light. We find the headlamps that separate the battery and the lighting system tend to feel more balanced and ride more comfortably than headlamps that place both units in the front.
PRICE
Headlamps can differ significantly in price depending on what functions you need for the activities you do. Because a headlamp is a safety item, we realized there are situations where choosing a more expensive headlamp may be a good idea. But we also include a budget option for situations where having the most lighting possible isn’t required.
WATER RESISTANCE
Headlamps should not rust or have electronic issues after external exposure to sweat or a sprinkle of water. While some headlamps we considered are more waterproof than others, on a good modern headlamp, moisture shouldn’t be able to reach a closed battery or USB ports. All of our winners have a minimum of an IPX4 water resistance rating, with our winner for longest running headlamp, the Black Diamond 400, having an IPX8 rating.
SECURE BATTERY AREA
We believe a headlamp should be made of quality plastic that won’t break when dropped. It should be easy to replace batteries or plug your headlamp in for a recharge. Flaps or panels that protect the batteries or charging port should be secure. They should not open during a run.
Bike Mount Capability
It's worth noting that none of the headlamps we considered are designed for use as a bike light. As a result, we did not use bike mount capability as a make-it-or-break-it criterion when judging headlamps.
However, some headlamps are convertible using bike mounting accessories designed to attach your headlamp to a helmet or a bicycle.
While a headlamp without the mounting accessories may work in a pinch, we think if you plan on doing any night riding, especially on a mountain bike, you're better served by getting a bike light that is made specifically for mounting on a handlebar or helmet.

WHEN TO USE A HEADLAMP VS A FLASHLIGHT
The brightest flashlight we've found is well over 100,000 lumens. That is brighter than all of the headlamps on the market. So why would someone choose a headlamp over a flashlight?
The advantage of a headlamp over a flashlight is that it is hands-free. This means you can use your hands for things like using trekking poles or scrambling or climbing rocks. If you’re hunting or fishing, you may need your hands to move aside brush and tree branches. Headlamps also make it easier to do camp chores that require your hands, like cooking dinner or setting up a tent in the dark.
The advantage of flashlights over headlamps is that they allow you to focus your beam better. Some runners, for example, prefer a flashlight to a headlamp because they can precisely focus their beam directly in front of them on the trail.
With a flashlight, runners can also prevent their shadow from impacting the beam. The brightest light mode of a flashlight is often spotlight mode, so if you're trying to find wildlife or get a very detailed look at a particular area, a flashlight may be a better option.
We think having the ability to use your hands is essential for most outdoor uses, making a headlamp more useful.
HOW TO GET THE MOST OUT OF YOUR HEADLAMP
Treeline writer Amanda Jameson on an after-work dayhike with a headlamp. Photo by John Carr.
There are a few things you can do to get the most battery life out of your camping headlamp and make its use more enjoyable for yourself and others.
Always check headlamp batteries before starting a trip.
If your headlamp has a lock mode, use it while in motion to prevent accidental battery use. Except for our budget winner, the Petzl Tikinna, all our recommended headlamps have a lock mode. If you aren’t sure how to use the lock mode, read the instructions before taking it into the field.
If reading your map by headlamp, use the white mode. This is because some topo lines and colors do not show up well in red-light mode.
Leave No Trace Outdoor Ethics offers guidance on how to respect other users in the outdoors. When in camp, headlamps can impact other users’ experiences, especially when shining headlamps in faces. If your headlamp has a red LED light, use that in camp so as not to blind campmates. Bonus: red light mode drains the battery at a lower rate.
A headlamp with few moving parts means less than can get stuck or break, making it suited for long distance backpacking trips. Photo courtesy Liz Thomas.
Remove the batteries before long-term storage. Moisture and sweat can cause battery corrosion and ruin your headlamp (we speak from experience!)
Always follow the manufacturer’s battery recommendation (e.g., alkaline, lithium). All of our recommended headlamps support alkaline and lithium batteries, but note that this isn’t true for all headlamps. Some headlamps, especially older models before the LED bulb, use bulbs that can't handle lithium batteries. However, all of our winners support lithium batteries.
Traveling in the cold? Use lithium batteries, not alkaline or rechargeable options. Alkaline batteries use a chemical reaction that uses a water-based electrolyte. Below freezing, an alkaline battery may have poor performance or not work at all. Rechargeable lithium batteries, like those found in the plug-in headlamps we recommend, may also perform poorly in cold conditions. If you are camping and think temps will be below freezing, consider keeping your headlamp in your sleeping bag to keep the battery from getting cold.

Care and maintenance
Taking good care of your headlamp not only extends its lifespan but also ensures that it functions reliably when you need it the most. Here are some essential tips for proper headlamp maintenance:
Keep it clean
Regularly wipe down your headlamp with a clean, dry cloth to remove dirt, sweat, and other debris.
For stubborn dirt or residue, use a damp cloth or a mild cleaning solution that is safe for plastics and electronics. Ensure the headlamp is completely dry before use.
Inspect seals and gaskets
All the headlamps we recommend have some waterproofing rating. However, if you anticipate any weather, check your seals and gaskets for any signs of wear, cracks, or damage.
Ensure that all seals are intact and free of sand, twigs, dust or anything else that could block it. Replace damaged seals promptly to maintain the headlamp's weather resistance. If you aren't sure where to get the right seals, contact the manufacturer. They will often send you one for free.
Battery care
For rechargeable headlamps, follow the manufacturer's guidelines for charging. Overcharging or letting the battery drain completely can affect battery life.
For devices that use disposable batteries, remove them when not in use for extended periods to prevent battery leakage.
Proper storage
Store your headlamp in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries to prevent corrosion.
Use the provided carrying case or a protective pouch to prevent scratches and damage.
Lens care
Clean the lens carefully using a soft, lint-free cloth to avoid scratching.
Avoid touching the lens with your fingers, as oils and residues from your skin can affect light output and clarity.
Adjust straps regularly
Over time, headlamp straps may become loose or stretched. Periodically adjust them to ensure a snug and comfortable fit on your head.
You may need replace your strap, especially if you loaned your headlamp to a friend with a big head.
Check for loose parts
Before each use (or at least, before an extended trip), inspect the headlamp for loose screws, brackets, or other components that may affect its stability or functionality.
Tighten any loose parts according to the manufacturer's instructions.
Avoid dropping or impact
Accidental drops or impacts can mess with the headlamp's internal components and the lens. Most of the headlamps we recommend are pretty rugged and are designed to handle some dropping. However, sometimes a small drop at a weird angle can cause more damage than a bigger drop onto a part that is designed to take more wear.
Replace batteries as needed
Using old or worn-out components can result in reduced brightness and performance.
If your headlamp uses replaceable batteries, follow the manufacturer's recommendations for replacement intervals.
Store spare parts and accessories
If your headlamp comes with spare bulbs, O-rings, or other accessories, store them in a place where you'll actually remember them! Consider putting a note for what they are. If you end up losing them or throwing them out, many manufacturers will replace them for free or a small fee.
Read the user manual
Always refer to the user manual that comes with your headlamp for specific care and maintenance instructions provided by the manufacturer.
Properly store and dispose of batteries
Store spare batteries in a safe, dry place, and keep them warm in cold weather to maintain their performance. Dispose of used batteries responsibly, following local recycling guidelines.
Headlamp care may not be the most exciting thing in the world, but speaking as someone who has destroyed many headlamps over the years, it can make a difference. Be sure to inspect your headlamp and at minimum, remove batteries if you don't plan to use your headlamp for a while. Your future self will thank you!
Safety tips for using a headlamp in the outdoors
A headlamp is an essential tool for outdoor adventures, but it's important to use it responsibly to ensure your safety and the comfort of others. Here are some safety tips to keep in mind:
Mind your beam angle
Adjust the beam angle of your headlamp appropriately. In crowded outdoor spaces or on shared trails, angle the light downward to avoid blinding others. For tasks like reading or working up close, tilt it upward to focus the light where you need it. Leave No Trace Outdoor Ethics offers guidance on how to respect other users in the outdoors.
Avoid staring directly into others' eyes
This one seems obvious, but when talking to others or passing by fellow outdoor enthusiasts, avoid shining your headlamp directly into their eyes. It can be temporarily blinding and disrupt their night vision.
Use dimming or red light mode when appropriate
Most headlamps come with dimming or red light modes. These are ideal for situations where you want to minimize the disturbance to others while maintaining visibility. Use a red light when reading in a shared tent or camping area.
Signal your presence
When hiking or running in the dark, especially near roads or on shared trails, use your headlamp to signal your presence to others. Make sure you're visible from a distance, and consider using a blinking mode for added visibility.
Carry a backup light source
While headlamps are reliable, they can malfunction or run out of battery. Always carry a backup light source, such as a spare headlamp, flashlight, camping lantern, or flares (at least, if you are in your car) to ensure you're never left in complete darkness.
Stay aware of your surroundings
Don't become overly reliant on your headlamp. Keep an awareness of your surroundings, as it's easy to become disoriented or miss important landmarks when relying solely on a narrow beam of light.
Secure the headlamp properly
Ensure that your headlamp is securely fastened to your head to prevent it from falling off during activities. This is especially true for runners or climbers. A loose headlamp can be dangerous to folks below you on the rock or trail.
Maintain a comfortable brightness level
Adjust the brightness level of your headlamp to match the situation. For tasks that require more precision, use a higher brightness setting. When navigating open trails or paths, use a lower setting to conserve battery and avoid blinding others.
Respect no-light zones
Some outdoor areas or parks may have designated "no-light zones" to protect wildlife or stargazing experiences. Always respect these rules and avoid using your headlamp in such areas.
FAQ
Are rechargeable headlamps better than those that use disposable batteries?
Rechargeable headlamps may be more cost-effective and environmentally friendly in the long run, but they may have shorter battery life compared to disposable battery options. The choice depends on your preferences and access to charging and recycling facilities. For many people, rechargeable headlamps are better due to convenience because it's easier to find a outlet than to get to the store to buy batteries.
What's the red light feature on headlamps for?
Red light preserves night vision and is less likely to disturb others in camp. It's useful for reading maps, checking on sleeping campmates, or moving around at night without fully adjusting to white light. It's also better for your night vision.
Can I use my headlamp underwater?
Some headlamps are designed for underwater use and have waterproof ratings, but most are not. Headlamps designed for underwater use are marketed that way–for snorkeling or diving. We would not recommend trying with any of the headlamps in this guide as they are not designed for underwater use.
Can I use a headlamp in extreme cold weather conditions?
Most headlamps are designed to work in cold conditions, but extremely low temperatures can affect battery performance. Keeping spare batteries warm and close to your body can help maintain their capacity in the cold.
Can I use my headlamp in rainy or wet conditions?
Many headlamps are designed to be weather-resistant or waterproof to a certain extent. Check the manufacturer's specifications to know the water resistance rating of your headlamp. While most can handle light rain, consider using an umbrella or wearing your headlamp under a hood during downpours.
