Best Rechargeable Headlamps

Why a headlamp is not a small flashlight

This inversion catches people out. On a handheld light, output per dollar is the sensible first filter — you can put a heavy light down. On your head, mass is the constraint that determines whether the tool gets used, and every gram sits on the same forehead for the same number of hours.

The published figures make the spread obvious. NITECORE's NU25 MCT UL weighs 47 grams including bracket and headband. Black Diamond's Spot 400-R weighs 86 grams. Petzl's ACTIK CORE weighs 88 grams. Those are near enough to double, and you feel it within an hour.

The runtime that matters is the low one

Nobody walks on turbo. You use a headlamp's maximum for a few seconds to look at something far away, and then you go back to the setting that lets you see your feet. That is why the low-mode runtime is the specification and the high-mode figure is a curiosity.

Black Diamond publishes it properly: 400 lumens for four hours, 200 for eight, and 6 lumens for two hundred and twenty-five hours. That last figure is not a novelty — six lumens is enough to move around a tent, read a map or find something in a pack, and 225 hours means the lamp is effectively an emergency reserve as well as a working light. NITECORE publishes up to 45 hours at 6 lumens on the NU25.

The spare-cell question

Almost every headlamp at this price seals its battery in. NITECORE's NU25 uses a built-in 700 mAh cell; Black Diamond's Spot 400-R uses an integrated 1,500 mAh cell. Both are good lamps, and in both cases when the cell tires the lamp is finished, and when it runs flat at 2 a.m. your night is over.

Petzl solved this and it is the reason the ACTIK CORE finishes where it does in our ranking despite not leading on any single number. It runs on the CORE rechargeable pack or on three ordinary AAA cells, and it detects which it has and adjusts. Petzl calls it the HYBRID CONCEPT. For anyone whose lamp has to keep working at the end of a long trip, that single feature outranks several hundred lumens.

How we ranked these

Four scored attributes: published output against live price, battery architecture including whether a fallback exists, weight, and usability. Weight replaces build quality in the headlamp rubric because it is the attribute that determines whether the lamp is worn, and a lamp in a pack is worth zero lumens per dollar.

Water ratings on headlamps, and why they vary so much

The spread here is unusually wide. Petzl publishes IPX4 on the ACTIK CORE — weather resistant, rain only. NITECORE publishes IP66 on the NU25. Black Diamond publishes IP67 on the Spot 400-R, tested to one meter for thirty minutes. Fenix publishes IP68 on the HM65R V2.0.

For most people IPX4 is genuinely adequate, because a headlamp is on your head and your head is usually above the water. It matters if you fish, paddle, work in a wash bay, or are the sort of person who drops things in streams. Our guide to IP ratings explains what each figure actually promises.

One thing no headlamp specification tells you

Balance. A lamp whose battery sits at the back of the strap feels lighter than one of the same mass with everything on the forehead, because the load is distributed. No manufacturer publishes a figure for this and we have not worn any of these lamps, so we cannot rank on it. It is the single best reason to try a headlamp in a shop if you can, and the reason to read someone who has actually worn them alongside this page.
