The key to finding the perfect headlamp is knowing what features are important to you. Think about the activities you plan to use your headlamp for – will you be camping on weekend trips with friends? Trail running on dark forested routes? Waking up early to catch the sunrise on skis?
Once you have a clear idea of how you’ll use your headlamp, you can think about what you need your light to do for you. Here are the main headlamp features to consider and help you make the right decision:
Headlamp brightness: The amount of lumens you need depends on what you’re doing.
USB or battery power: Rechargeable lights and replaceable batteries each have pros and cons.
Battery life: How long do you need your light to last?
Beam pattern and distance: Find out if focussed or flood light is better for you.
Red-light mode: Super useful for a few reasons.
Other factors to consider: Kid-friendly headlamps, lock-out mode and more.
How bright should your headlamp be?
Lumens are the standard unit for measuring brightness. You’ll see headlamps ranging from 20 lumens all the way to a whopping 1,500 lumens or more.
The headlamp’s optics focus the lumens, which directly translates to how much light goes where you want it. Well-known headlamp brands like Petzl, Black Diamond, Fenix and Silva have their optic technology dialled. When you’re looking at headlamps from a major brand, the number of lumens is a safe way to gauge how bright the headlamp is. Lower quality brands with a high lumen number may not seem as bright due to the quality of the light’s optics.
The amount of lumens you need depends on what you’re planning to use it for – brightest isn’t always best. Almost all lights have a high, medium and low mode, so a high-output light can still give you low output options. Some general tips:
Low lumens (25+): Good for setting up camp in the dark, reading in the tent, doing close-up work, walking the dog, keeping in an emergency kit, or using anytime you’re in a group (an extremely bright light can be annoying).
High lumens (200+): Good for running in the dark or night hiking
Higher lumens (600+): Good for evening mountain biking or skiing.
Really high lumens (1,000+): Good for spotting poorly flagged trails, skiing or biking at high speeds, or for search and rescue.
USB or battery power sources
Always think about how you’ll recharge your light. If you’re looking for a headlamp for weekend epics, evening runs or walking your dog, then a rechargeable light is a great option. But if you’re going backpacking around the world, then a light that uses a widely available battery is a very good idea.
Rechargeable lights: Hassle-free USB recharging with almost any power source: wall outlets, portable power banks, AC chargers or solar chargers. Just don’t forget the charging cord, especially if it needs a custom charger. Easy to have full power ready to go, instead of squeezing the last out of batteries.
Replaceable batteries: AA or AAA batteries are easy to find almost anywhere and provide instant power. But you’ll need to bring extra batteries, recycle used ones and buy new ones.
Some headlamps are powered by both USB or batteries, so you can get the best of both power-source worlds.
In general, the brighter a light’s output, the shorter its battery life. When you look at headlamp specs on mec.ca, you’ll see “burn time” listed for different modes. The amount of time the battery lasts will be different for the modes (low, medium, high or flashing). Think about what modes you’ll use the most and find a light that runs efficiently in those modes.
As the battery drains, some LED lights get progressively dimmer. That might not be a problem if you’re on a week-long hike and moving slowly or urban running in the evening. But if you’re trail running or mountain biking at night, you want your light to stay bright. For steady brightness, look at headlamps that have regulated output (check the product specs tabs on mec.ca). Regulated output lights have intelligent circuitry that keep the LED light at a constant brightness until the batteries can no longer support that output. Once that happens, the light dims to a low output, usually for an hour or so – hopefully enough light to get to where you’re going safely.
Batteries and cold weather
Ever had your phone battery die in cold weather? It can happen with headlamps too. If you need a light for prolonged cold-weather use, then look at headlamps with external battery packs. External battery packs easily fit inside your jacket pocket to keep the batteries warm so you can get better performance.
Beam pattern and distance
Most lights put out either a focussed spot beam or an even flood light, and some headlamps will do both. The beam pattern is listed on the specs tab for each headlamp on mec.ca.
Spot beam: If you’re looking for a headlamp to help you squeeze in one more run in the backcountry or make dawn patrol a bit safer, then a focused spot beam to light up things in the distance will serve you well.
Wide beam: If you’re using a headlamp around camp or working on problems at the bouldering crag after sunset, a wide flood beam is a better option.
Mix of both: Lights that have both a spot and a flood light are great for fast-paced activities like trail running in the dark or biking at night. The combo of beam types helps you see changes in terrain in front of you and what’s further ahead.
How far a light throws its beam is also important. But there are some inconsistencies around how different brands report beam distance. To get a realistic idea of how far a headlamp will light things up, take the beam type and the number of lumens into consideration, and then look at the claimed beam distance.
Red lights on headlamps
A red-light mode is surprisingly useful. Red light is less obtrusive at night, so it’s perfect for reading in your tent or waking up to answer the call of nature without disturbing your tentmates. It also helps you keep your night vision, since red light doesn’t cause your pupils to constrict the same way white light does. Plus it’s handy for viewing wildlife in the dark or star gazing.
Other useful headlamp features
Lights designed for kids are often smaller, brightly coloured, more lightweight and not as powerful. Features like automatic shutoff are great for young campers. Keep in mind that LEDs are bright enough to cause permanent vision damage, so make sure your little one knows how to use their light responsibly.
Plan to use your headlamp in bad weather? Look into waterproofness. Water-resistance of electronics is usually rated on the IPX scale, from IPX-0 (no water resistance) to IPX-8 (essentially waterproof, though the manufacturer will define the parameters).
Headlamps built for the outdoors have at least some waterproofing, usually starting around IPX-4 (protection from splashes from any direction for at least 5 minutes) to IPX-7 (protection from submersion up to 1m for at least 30 minutes).
Many headlamps for outdoor use are roughly the same size and weight. But if you want to save grams, headlamp weight is one thing to consier.
Weight is usually goes hand-in-hand with features (lighter = less features, heavier = more features), so it’s important to know exactly what you want from your light, and what you can do without. Once you have a clear idea of your needs, you can find headlamps that tick all your boxes and then choose the lightest.
Tip: For those truly looking to cut weight, consider lithium batteries. Lithium batteries are lighter than their alkaline and NiMH counterparts, and perform better in cold weather. But be warned that they’re also more expensive.
Some headlamps have a lockout mode, so a bump or accidental button press will not turn the light on. This feature is handy if you throw your light in your backpack or tool box.
Flashing or boost modes
Flashing modes are real eye-catchers, especially if you plan to cycle with your light. And boost or turbo modes can be great for moments where you quickly need extra brightness. Think: Which fork should you take on the trail? Or “What was that noise?”
