About this deal

According to the company’s figures, using the minimum power of the main beam will give 190 hours of 4 lumens light, illuminating up to 9m, dropping to only 8m after 10 hours. But, you could also just consider that a benefit, I guess. You can get the most out of the regular batteries, and when you need a stronger performance of the ReVolt, just put 3 AAAs in it. In addition to that, there are 3 different night vision modes on this headlamp, which is a really cool feature. There are several different lighting modes to which you can set this lamp, as well as an indicator of remaining battery life. Additionally, the Brightness Memorywill allow you to set a particular level of brightness to which the lamp will revert to when you turn it off and then on again. Pretty cool, right?

After 10 hours using the two single-power LEDs, there is very little difference in range between full and minimum power, being 3m and 2.4m respectively.Then again, 160 hours on the low light setting is a pretty good burn time. However, if you set it to the highest brightness setting (350 lumens), the difference is drastic. In fact, the Actik Core has a battery life of only 2 hours in this setting, which is somewhat disappointing. The worst scoring products were those whose operation required reading the manual. The Petzl Reactik+ is the worst with a score of 3/10. It has small buttons, and Petzl's innovative (but not generally loved) "Reactive" mode complicates use. Without a manual handy, it is easy to be left simply guessing at which of the two buttons does what — Reactive is a wrench in the works in the operation of a device we'd like to be fall-off-a-log easy to use, we're not fans. Gloved Use One interesting thing that came up in my desultory battery research was that the temperature at which batteries are charged can play a big role in performance and longevity. Short lesson: Don’t charge batteries at extreme temperatures! Weight: the Storm is a little heavier than the Revolt (although we are talking under half an ounce) I think the ReVolt is an excellent headlamp if used with regular batteries primarily, but that there are just too many little gotchas with the NiMH batteries to really count on them for primary use. While NiMH batteries and a built-in battery charger are included in the headlamp, they don’t provide as much power as non-rechargeable AAA batteries, they don’t work in cold temperatures, and they need to be recharged more frequently between uses. Still, there are use cases where having the NiMH batteries and built-in charger can be convenient and save you money and hassle over carrying spare AAA batteries.

For minimalists and true ounce-counters, our favorite ultralight headlamp of 2023 is the Nitecore NU25 400 UL. At just 1.6 ounces, the Nitecore secures via a streamlined elastic headband, is surprisingly bright with a 400-lumen max output, and is rechargeable via micro USB. We’ve also found it incredibly easy to operate (cryptic toggling between modes is a common issue with headlamps), with one button for the white beam and one for red, and the battery seemingly lasts forever. All told, as a high-powered emergency light or for those trying to keep their load as light as possible, the NU25 UL is a bright and relatively cheap option.In terms of the bean length, the low setting is perfect for any activities where you are focused on your immediate surroundings. The medium settings will be great if you are moving around a lot, and the high setting will allow you to see almost 200 feet in front of you.
