Best rechargeable headlamps

A 3,400 mAh 18650 at a nominal 3.6 V is 12.2 watt-hours. That is more energy than a Petzl NAO RL carries, in a lamp 5 g lighter, because a bare 18650 is a more efficient package than a molded pack.

It is also the only headlamp in this set whose battery you can replace at a checkpoint for three dollars, because 18650 is a standard cell and not a proprietary brick.

IP68 rather than IPX4 is the second real difference. This one survives being dropped in water; most of the running lamps here do not.

Skip this ifyou count grams. A Swift LT does the camp job at 43 g; you are carrying 97 g extra for reach and a removable cell.

8.47 watt-hours across 92 grams is the whole argument. That works out to 13.0 lumens per gram at peak and 0.092 Wh of stored energy per gram carried, the best combination of the two figures in this roundup.

Reactive lighting is the runtime strategy, not a gimmick. The lamp meters reflected light and cuts output when you look at your own hands or a pale trail. Petzl's 7-hour minimum at medium is quoted in that mode, and it is the number to plan around.

168 m of throw is more than a runner can use below about 8 minutes per kilometer. What you actually notice is how little the beam sags once the pack drops under half.

Skip this ifyou mostly walk. You are paying for a reactive sensor and a 2,250 mAh pack to solve a problem hikers do not have.

625 lumens and 115 meters is a walking beam, not a searching beam. The FL1 definition puts illuminance at 115 m down to 0.25 lux, which is enough to tell that something is there and not enough to identify it. In practice you run the middle level and see 30 to 60 m of usable trail.

4.5 watt-hours matters more than the lumen figure. A lamp drawing a regulated 2 W empties that pack in a bit over two hours. The 400-hour number Petzl quotes is a reserve-mode visibility claim, not 400 hours of light you can walk by.

The hybrid design is the real feature. When the CORE pack dies three hours into a night descent, three AAA cells from a gas station bring the lamp back. Very little else at this price does that.

Skip this ifyou need reach. 115 m is short by 2026 standards, and the 625-lumen headline does not change the shape of the beam.

1,400 lumens at this price is the whole pitch, and it is a real pitch: nothing from Petzl at the same money publishes a number that high.

A spot and a flood emitter together is the right architecture for a general-purpose lamp. One beam shape never covers both map-reading and trail-finding.

Everything except output and charging is unpublished in the source we could reach, which is why this sits below the Fenix and Petzl picks despite the bigger headline.

Skip this ifthe runtime matters more than the peak. Without a published runtime table you cannot plan a night around it, and we will not estimate one for you.

3,000 lumens at 160 m tells you this is a flood-biased beam. For comparison, a Petzl Swift RL reaches 168 m on 1,200 lumens — more distance from 40 percent of the output, because distance comes from intensity, not from lumens.

The two-in-one design is the real selling point. A right-angle light that clips to a pocket and also mounts on a strap replaces two tools.

Marketing copy calling it waterproof without an IP number is exactly the kind of claim we will not repeat as a specification.

Skip this ifyou want distance. The published figures say flood; a 1,200-lumen Petzl reaches further.
