How to Choose a Headlamp

The short answer

Headlamps are sold the way flashlights are sold: on a single peak number. For a lamp strapped to your head, that number is close to irrelevant. Almost nobody walks on maximum, every lamp steps down from it within minutes, and the modes you will actually live in sit between 5 and 100 lumens. What follows is the order that matters instead.

Decision 1: how it is powered — and this is most of the decision

There are three architectures and they fail in completely different ways.

• Sealed rechargeable. Lightest and cheapest to run. When the cell is flat you need a power bank and time, and when the cell wears out the lamp is refuse. NITECORE's NU25 MCT UL is the best of these at 47 grams.
• Hybrid. A rechargeable pack that can be swapped for ordinary AAA cells. Petzl's CORE system does this on the ACTIK CORE and TIKKA CORE: 625 or 450 lumens on the pack, 500 or 350 on three AAAs. Heavier and dearer, and it cannot strand you.
• Primary cells only. Nothing to charge, nothing to degrade, and you buy batteries forever. Rare now at the quality end.

The honest rule: if the lamp is safety-critical — a trail after dark, a night shift, a route you cannot stop on — buy hybrid. If it is for a tent, a dog walk or a loft, sealed rechargeable is lighter, cheaper and perfectly sensible. Our guide to rechargeable versus battery lights works through the economics.

Decision 2: the low mode, not the high one

The specification that predicts how useful a headlamp is day to day is the runtime at its lowest usable setting, because that is where it spends its life. Compare these four published figures and the differences are enormous.

Two hundred and twenty-five hours against forty-five is not a rounding difference, and neither lamp advertises it. Both advertise 400 lumens.

Decision 3: weight, measured where it sits

A headlamp is the only light whose weight you feel continuously, and the band that matters is roughly 45 to 120 grams. Below about 60 grams the lamp disappears; above about 100 it bounces when you run and presses when you wear a hat under it. Petzl publishes 88 grams for the ACTIK CORE and 84 for the TIKKA CORE, Black Diamond 86 for the Spot 400-R, NITECORE 47 for the NU25 MCT UL including bracket and headband.

Weight and battery architecture are the same decision seen twice: hybrids carry the mass of a pack that a sealed lamp does not. Decide which failure you are buying against, then take the weight that comes with it.

Prices pulled October 18, 2026. Lumens per dollar is the manufacturer's published maximum output divided by that price, recomputed every time the price moves.

Decision 4: red light, and whether you can reach it

A red mode preserves dark adaptation because rod cells are far less sensitive at the red end of the spectrum, and it stops you blinding whoever is sitting opposite you. Nearly every lamp has one now. The specification that separates them is whether red is one press away or buried behind the white sequence — a red mode you have to cycle through 400 lumens to reach defeats its own purpose every single time you use it. Our ranking of red-light headlamps goes through the implementations.

Decision 5: the water rating, as a number

Petzl publishes IPX4 on both CORE lamps, Black Diamond IP67 on the Spot 400-R, NITECORE IP66 on the NU25. IPX4 is splashes and rain from any angle; IP67 adds dust and immersion to one meter for thirty minutes. For most people IPX4 is genuinely enough — a headlamp is rarely submerged and often rained on. If the lamp will go in a boat, a cave or a river, the higher number earns its money. Our guide to IP ratings sets out what each digit actually certifies.

Decision 6: lock-out, which sounds trivial until it is not

A headlamp in a pack is a switch waiting to be pressed by a water bottle. A lock-out function — a long press, or physically reversing a battery — is the difference between arriving with a charged lamp and arriving with a warm, empty one. Check it is there before you check anything cosmetic.

1. Lightest headlamp with a real published runtime

NITECORE NU25 MCT UL

Lumens per dollar

11

Forty-seven grams including the headband, 400 lumens, and 45 hours at its 6-lumen setting. On a headlamp the weight figure matters more than the lumen figure, because the lamp you stop wearing produces no light at all.

Max output

400 lm

Runtime

45 h at 6 lm

Battery

Sealed

Water rating

IP66

What it gets right

• Forty-seven grams with the band on — you forget it is there
• Three color temperatures plus red, which is unusual at any price
• IP66 and a published 45-hour low-mode runtime

What it gets wrong

• Sealed 700 mAh cell; no way to carry a spare
• Four hundred lumens is modest for trail running at speed
• Flat band with no over-the-top strap on the ultralight version

Published specification

• Maximum output: 400 lumens — NITECORE published specification
• Beam distance: 132 m — NITECORE published specification
• Runtime: Up to 45 hours at 6 lumens — NITECORE published specification
• Battery: Built-in 700 mAh Li-ion, USB-C — NITECORE published specification

• Color temperatures: 3,000K / 4,500K / 6,500K plus auxiliary red — NITECORE published specification

Skip this one if

you need to swap a battery mid-shift. A sealed 700 mAh cell means your night ends when it does.

Buy it if: hikers, campers and anyone whose complaint about headlamps is that they bounce.

2. Best hybrid: rechargeable or AAA cells

Petzl ACTIK CORE

Lumens per dollar

8

Six hundred and twenty-five lumens stated to ANSI/PLATO FL1, 88 grams, and — the part that matters — it runs on the CORE rechargeable pack or on three AAA cells when the pack is flat. That is the answer to the sealed-battery problem, from the only brand here that bothered.

Max output

625 lm

Runtime

Published per mode by Petzl

Battery

Replaceable cell

Water rating

IPX4

What it gets right

• Explicitly states ANSI/PLATO FL1 conformity, which most brands here do not
• Hybrid power: the pack for daily use, AAA cells as the fallback that never fails
• Petzl publishes the CORE pack's cycle rating, so its service life is a stated number

What it gets wrong

• IPX4 — weather resistant, not submersible
• Eighty-eight grams is not ultralight
• The CORE pack is a Petzl part rather than a standard cell

Published specification

• Maximum output: 625 lumens (ANSI/PLATO FL1) — Petzl published specification
• Weight: 88 g — Petzl published specification
• Battery: CORE rechargeable 1,250 mAh / 3.6 V / 4.5 Wh, or 3 x AAA — Petzl published specification
• Battery compatibility: Alkaline, lithium or Ni-MH — Petzl published specification
• Water rating: IPX4, weather resistant — Petzl published specification
• Warranty: Lamp 5 years; CORE battery 2 years or 300 cycles — Petzl published specification
• Lighting levels: MAX BURN TIME, STANDARD, MAX POWER, plus red — Petzl published specification

Skip this one if

you want a submersible headlamp. IPX4 covers rain and nothing beyond it.

Buy it if: anyone whose headlamp has to work at the end of a long trip, when charging is not an option.

3. Best hybrid headlamp at the lower price

Petzl TIKKA CORE

Lumens per dollar

8

The ACTIK CORE's argument in a cheaper, lighter package: 450 lumens stated to ANSI/PLATO FL1, 84 grams, and the same CORE pack or three AAA cells when the pack is flat. Petzl publishes a lumen figure, a beam distance and a burn time for every mode on both power sources, which almost nobody else does even once.

Max output

450 lm

Runtime

2 h 30 min at 450 lm; 110 h at 7 lm

Battery

Replaceable cell

Water rating

IPX4

What it gets right

• Lumens, beam distance and burn time published for every mode on BOTH power sources
• States ANSI/PLATO FL 1 conformity, which most brands at this price do not
• Runs on three AAA cells when the CORE pack is flat, with no adapter to lose
• One hundred and ten hours at 7 lumens is a genuine emergency reserve

What it gets wrong

• IPX4 — weather resistant, not submersible
• Four hundred and fifty lumens is modest against lamps at similar money
• Output drops to 350 lumens on AAA cells, which Petzl states but buyers miss
• The CORE pack is a Petzl part rather than a standard cell

Published specification

• Maximum output: 450 lumens (ANSI/PLATO FL 1) — Petzl published specification
• MAX POWER on CORE: 450 lumens, 75 m, 2 h 30 min — Petzl published specification
• MAX POWER on AAA: 350 lumens, 70 m, 2 hours — Petzl published specification
• STANDARD on CORE: 100 lumens, 45 m, 7 hours — Petzl published specification
• STANDARD on AAA: 100 lumens, 45 m, 12 hours — Petzl published specification
• MAX BURN TIME: 7 lumens, 10 m, 110 hours on either source — Petzl published specification
• Red lighting: 2 lumens, 5 m, 60 hours continuous — Petzl published specification
• Battery: CORE 1,250 mAh / 3.6 V / 4.5 Wh, or 3 x AAA — Petzl published specification
• Weight: 84 g — Petzl published specification
• Water rating: IPX4, weather resistant — Petzl published specification
• Warranty: Lamp 5 years; CORE battery 2 years or 300 cycles — Petzl published specification

Skip this one if

you want maximum output for the money. This lamp spends its budget on documentation, hybrid power and a five-year warranty, and a budget rechargeable will out-lumen it for less.

Buy it if: anyone who wants Petzl's hybrid-power argument without paying for the ACTIK CORE's extra output.

4. Most complete published runtime table

Black Diamond Spot 400-R

Lumens per dollar

7

Four hundred lumens for four hours, 200 for eight, 6 for two hundred and twenty-five. Black Diamond publishes lumens, runtime and beam distance for all three modes, and IP67 on top. There is nothing to guess at here.

IP67

What it gets right

• Lumens, runtime and distance published for every mode
• Two hundred and twenty-five hours on low is a genuine emergency reserve
• IP67 and a battery meter that shows an actual percentage

What it gets wrong

• Micro-USB in a year when everything else is USB-C
• Integrated battery — no spare, no re-cell
• Eighty-six grams is heavy next to the ultralight class

Published specification

• High: 400 lumens, 4 hours, 100 m — Black Diamond published specification

• Water rating: IP67, tested to 1.0 m for 30 minutes — Black Diamond published specification
• Weight: 86 g — Black Diamond published specification

Skip this one if

you have standardized on USB-C. Carrying a second cable for one device is a small annoyance that compounds on a long trip.

Buy it if: camp, dog walks and anyone who wants a headlamp whose numbers are all on the box.

How we ranked these

Published output over live price, as everywhere on this site, with battery architecture weighted hardest and weight scored in place of build on headlamps. A lamp that publishes a complete per-mode table scores above one that publishes a single headline figure, because a number you can check is worth more than a number you cannot.

How many lumens do you actually need on your head?

Beam shape, which no headlamp sells itself on

Headlamps are bought on lumens and used on beam shape, and the two have almost nothing to do with each other. A headlamp sits a few inches above your eyes and points where you look, which makes a tight beam actively unhelpful for most jobs: you get a bright circle on the ground, an immediate contrast edge around it, and nothing useful in your peripheral vision.

What you want for walking, camp chores and work at arm's length is flood — a wide, even pool with soft edges. What you want for picking a line down a technical descent, or spotting a trail marker across a slope, is some reach. Lamps that publish a beam distance tell you which they are: Petzl publishes 75 meters for the TIKKA CORE at 450 lumens against Black Diamond's 100 meters for the Spot 400-R at 400, and that difference is beam shape, not output.

The better lamps hedge by giving you both emitters and letting you mix them. Where a lamp has only one, assume flood unless a beam distance says otherwise, and treat a very long published distance on a small headlamp as a warning that its wide mode may be mediocre.

The headband, which decides whether you wear it

Three things about the strap matter and none of them appears as a number. Whether there is a top strap: on anything above about 100 grams, or anything you will run in, a crown strap is the difference between a lamp that stays put and one you re-seat every ten minutes. Whether the band is washable: a headlamp worn against a forehead for a season is a genuinely unpleasant object by spring, and removable electronics make that fixable. And whether the tilt ratchet holds: a hinge that creeps downward under its own weight will aim at your boots by the end of a walk, which is the most common complaint about cheap lamps and the hardest to check before buying.

Battery placement belongs here too. A lamp with the cell at the back of the band balances better than one with everything at the front, which is why heavier hybrid lamps often feel lighter in use than their weight suggests. It also means the weight figures in the table above are not directly comparable to how two lamps feel.

What we cannot tell you

We have not worn any of these lamps. We cannot tell you how a given headband sits under a helmet, how the beam of one compares with another in person, how much any of them bounce at a running cadence, or how long a CORE pack lasts in real seasons of use. Every figure above is published by the manufacturer named beside it, and the ordering of the six decisions is our editorial judgment, stated as such.
