12 Best Ultralight Backpacking Headlamps

A guide to the best headlamps for ultralight backpacking and trail running.

At a Glance:

‣ A backpacking headlamp is used primarily to light up things nearby, and only illuminate the trail at night occasionally.

‣ Headlamps for ultralight backpacking should weigh less than 2 oz, have at least a 30 lumen brightness, and have a battery life of at least 40 hours on the dimmest setting.

‣ Headlamps should have an IPX (water-proofness) rating of at least 4 and have a beam distance minimum of 10 meters.

‣ Rechargeable headlamps are more cost efficient in the long run and they’re better for the environment.

80% of of the time your headlamp will be used to illuminate small items in close range—gear in the tent or food while cooking, for example. The other 20% of the time your headlamp will be used for short walks at night. Therefore, you want to opt for a headlamp that will light up things nearby and illuminate the trail at night only when need be.

Your headlamp will be used for short walks but not full on hiking at night. A short walk might be going to fill up at the water source, use the bathroom, find firewood, etc. Usually, you will be at camp before nightfall and not hiking for miles in the dark.

Hiking at night can be fun... and totally necessary during an emergency. But, these will not be the main uses for your headlamp and you should not buy one for these less common circumstances.

Also, note we are NOT talking about high-powered lanterns designed to brighten up the family campsite nor beam-like spotlights designed to shine on distant wildlife. We are specifically talking about ultralight headlamps designed for long distance backpacking.

Things to Consider


Most headlamps will weigh anywhere between 2-4 oz, and since disposable batteries are typically grouped together to provide power, you’ll have to pack enough backup batteries if going on a long thru-hike. This can definitely add weight to your pack. But with rechargeable batteries, you only have to pack the battery and a USB charger, which will save on weight and storage space.

You will hike during the day. Therefore, your headlamp will be packed away… on your back almost all the time. Some more powerful backpacking headlamps get up to 10+ oz. No thanks. Keep it around 3 oz or less (including batteries). You should be able to get a headlamp with plenty of power for only a few ounces.


A 30 lumen headlamp is adequate. We know ultralight backpackers that actually hike with 10 lumen keychain flashlights that clip onto their hats. That said, technology has advanced so much though that you rarely see headlamps on the market with under 100 lumens anymore.

One lumen is a standard unit of measurement equivalent to the amount of light a single candle emits during a single second. Lumens are also used to measure the amount of light a headlamp puts out. The higher the lumens, the more light your headlamp emits.

For example, most indoor lighting you’ll find ranges anywhere between 200-300 lumens. Most headlamps offer a wide range of lumen output settings so you can adjust the brightness to fit the specific task at hand.

Keep in mind bright headlamps with high lumens come with an achilles heel though—their batteries can drain at an alarmingly fast rate. Simply put, high-powered lights require more juice than low-powered lights. We’ll get to battery life in a minute. Just understand that there is a trade-off between lumens and battery life.

Beam distance measures how far the light goes. The beam distance of a headlamp can range from as low as 10 meters up to a whopping 200 meters. However, the standard max beam distance offered in both rechargeable and disposable battery headlamps these days is between 50 and 100 meters.

The light from your headlamp can be emitted in any direction. As you can imagine, a 70 lumen light bulb will emit light very differently than a 70 lumen spotlight. This is where beam distance matters. Besides direction, the battery life and lumen count of your headlamp will also affect the overall beam distance. 

What you'll need depends on how much night hiking you plan on doing. If night hiking, having a strong beam can really help cut through dense fog, identify slippery rocks on stream crossings, or assess the slope of the trail.


Another great feature about headlamps is their adjustable beam settings. There are many options to fit all your night-time lighting needs. Here are the most common settings and what they were designed for:

  • Spotlight: The spot setting provides a high intensity and sharp beam of light—like the spotlight from a theater performance. This setting provides the farthest and most direct beam of light available for a headlamp. This setting is ideal for seeing long distances.

  • Floodlight: The floodlight setting illuminates the area directly around you. It provides low intensity and broad light—like the lightbulb from a lamp. It’s less bright overall compared to the spotlight, and is best for close-up activities like maneuvering around camp, reading, writing, or working on projects.

  • Red: This setting is very low-intensity and, therefore, drains a minimal amount of battery. Lots of hikers use the red light instead of the normal white LED for that reason. The dim red light might feel a bit strange at first, like you are in a military operation, but you'll soon get used to it. Like the floodlight, is best used in close proximity while also saving on battery life.

  • Signal Beacon: The signal beacon setting (aka the ‘strobe action’) puts out a red blinking light. This beam setting was designed to be used in case of emergencies, as the flashing red light can be seen from far away and is recognized universally as a distress signal.

Most headlamps come offered in either a two-band or three-band option. Where a 2-band headlamp wraps directly around your noggin, a three-band option has an extra band that goes over the top of your head.

We vote keeping the straps simple and horizontal without that extra vertical strap commonly seen used on hard hats and helmets.

Some ultralight headlamps come with a thin retractable string to strap around your head. Some come without any straps and only use a small clip for your visor or to attach to your pack’s shoulder strap.

Others come with a 2-inch wide and well-cushioned elastic strap. Admittedly the small strings can be quite constricting and uncomfortable, like a wire.

Most straps today are made from elastic that can be adjusted, removed and even washed. While adjusting your straps, make sure they’re tight enough to hold your headlamp in place while walking or running, but not too tight where your giving yourself a headache.

Whereas some batteries (single-use and rechargeable alike) can lose power over time and decrease beam distance, others will stay the same no matter what level the batteries are at.

  • Standard lighting: brightness decreases because the battery is losing power. This is a common problem with disposable batteries as well as rechargeable headlamps. 
  • Constant lighting: the headlamp’s brightness and light emitted stay consistent over the entire burn time. Foxelli's MX200 headlamp is one of the few ultralight headlamps on our list that offers constant lighting. In other words, you’re guaranteed to have the same constant light output throughout the entire battery’s life.
  • Reactive lighting: a headlamp auto-adjusts its light output level based on its environment.

The water resistance level in headlamps is measured on an “IP” or “Ingress Protection” rating system. Look for “IPX” followed by a number from 0 to 8 in the product description. As a point of reference:

  • IPX0 means no resistance at all to water
  • IPX4 means it can handle splashing water
  • IPX8 means it is completely submersible.

When buying a headlamp, look for a product that has a rating between IPX4 and IPX8. 


Some high-powered headlamps suck the life out of batteries and, on their highest setting, can last a measly 2 hours. That’s pretty thin if you are planning on backpacking for several days at a time. Most headlamps let you adjust the intensity of the beam, and thus, adjust the rate at which the battery is drained (aka “run time”).

In order to understand the full range of run time of a particular model, always look at the low end and high end of intensity.

On the low-intensity and battery-saving setting, a headlamp should always be able to last at least 20 hours. That's a few hours for every night you are out on the trail plus some in case of an emergency.

DIY: “Clip Lights”

  • Price: $15
  • Weight: 0.25 oz
  • Lumens: 4.5 Lumen
  • Max Beam Distance: U/K
  • Waterproofing: IPX7
  • Run time: 18 hours

Clip lights are favored by ultralight backpackers who strive to shed every ounce of weight from their kit. With a price tag under $15, these quarter-sized keychain flashlights are affordable and lightweight (0.25 ounces). They are easy to attach anywhere you need them, but their 10 lumens output is meager. This level is adequate for working around the camp, but not bright enough for technical nighttime hiking by most hikers. They are a niche item for backpackers who are not bothered by the darkness and willing to sacrifice light output for lightweight.

Additional Features


Having a headlamp that can adjust to different angles is fairly standard. Be sure your headlamp can tilt in a few positions and is not fixed in place. Otherwise your tired head and neck will be relied on to adjust to each desired view. The overall tilt your headlamp has is a great benefit because it lets you easily point and direct your light wherever you need it. With a headlamp that tilts, you can point the beam down, up or straight ahead, focusing the beam however suits you best. The level of tilt offered varies with each product, as some headlamps give free rein, while others will have predetermined settings built in. 


Reactive technology in rechargeable headlamps is a light sensing feature that helps extend battery life. It works by automatically adjusting the light from your headlamp to properly suit your environment. Reactive technology detects the amount of light that’s directing back into the headlamp’s sensors, thus putting out the proper lighting needed. This is a great feature that will not only extend battery life, but also will allow you to go from looking down a trail, to close at a map seamlessly. Reactive technology is great, but there is one downfall… it doesn’t take bugs into account. So, if one flies in front of you, you better believe your headlamp will adjust accordingly.


When shopping for headlamps, checking if it has an on/off lock is something to take into consideration. This is an added feature that can ensure your headlamp doesn’t accidentally get switched on in your pack during the day, which would inevitably lead you to a light-less night.


If you’re an App fan and enjoy having your techy gadgets synced to your smartphone, then there’s technology and headlamps nowadays that let you do so. With a Bluetooth-enabled headlamp you can sync the program to your phone, which lets you quickly check your remaining battery power, set specific lighting profiles, and even adjust your headlamps brightness. As for safety benefits, with a Bluetooth enabled headlamp you can type a distress message on your phone, and your headlamp will convert that message into a flashing Morse code signal.


Some rechargeable headlamps even provide a built-in battery indicator so you’ll always know when it’s time to recharge. Other headlamps have small lights on them that will communicate this when plugged in by flashing green to show “fully charged,” or blink red communicating it needs a longer charge time.

Rechargeable Headlamps vs. Batteries


With rechargeable batteries, you can fully charge your headlamp ahead of time knowing you're going out on the trails with 100% power. With a disposable option, you may be left gambling with just how much battery life you actually have left.

"I hate trying to gauge if my batteries are full or not... and then going to the store to buy some just in case they're not full." -Chris, Founder


Although the initial cost of a rechargeable headlamp is higher up front, if you use your headlamp often there’s no doubt that it’ll end up saving you money in the long run. Since most rechargeable headlamp batteries are good for hundreds of hours and around 700 cycles, you won’t have to worry about constantly buying disposable batteries, which let’s face it… can add up.


When using a rechargeable headlamp, all you need is the headlamp itself and a small power source to recharge. Since most rechargeable headlamps come with a USB charging cable, a portable USB power bank would work perfectly. This will save weight on carrying around packages of disposable batteries. That said, most rechargeable headlamps offer a back-up option to be powered by batteries, so you may want to carry one set of disposable batteries in case the headlamp runs out juice and you don't have access to a power source to recharge.

USB charging port (Biolite)


If you’d like to get some brownie points with mother nature, choosing a rechargeable headlamp over a disposable option is a great step in the right direction. First off, you won’t have anything to throw away once your battery loses its charge. Just plug it back in for a few hours and your good to go! Second, you won’t have to worry about hauling around those dead batteries in your pack to properly dispose of after they’ve run dry.


There are a few downfalls to rechargeable headlamps compared to disposable options. The first being that rechargeable batteries will lose their charge when not being used. The second is overall burn time. Depending on the setting of your headlamp, a rechargeable battery can give off 40-90 hours of lighting per charge. A disposable battery has been said to double that time, although the overall light output will get dimmer.
