Black Diamond's Revolt 350 Headlamp has been updated to provide a lot more punch. The new battery design gives this a maximum output of 350 lumens and a maximum battery life of 200 hours.
Black Diamond says:
Now running on our new modular BD 1800 rechargeable battery, the Black Diamond ReVolt350 is a powerful, versatile and rechargeable headlamp that has now been fully redesigned. Now producing 350 lumens of light, we’ve also updated the user interface by adding a second switch for easy lens mode selection. In addition, the improved optical efficiency provides brighter light with more peak intensity, and you can track the battery life with a six-setting, three-LED battery meter. The ReVolt350 easily spots anchors while you rappel in the dark while its proximity lighting gives you a large area of light for hiking down the trail. Brightness Memory gives you the option to set the light's brightness when first turned on, plus PowerTap Technology makes for instant brightness adjustment settings. The ReVolt350 can run on standard AAA batteries or the included BD 1800 Battery.
The Revolt 350 Headlamp has a new rechargeable battery from Black Diamond providing a greater maximum output of 350 lumens and a much longer battery life (up to 200 hours on the lowest setting). With this kind of performance it is more than enough for most overnight adventures and has proved just as reliable on multiday trips year-round.
As usual, there are a range of settings that allow you to tailor the headtorch to your liking. With a number of options for full strength in proximity and distance modes, dimming, strobe, red night vision and lock mode. The brightness memory is a great feature, especially for navigating and regular use. The PowerTap control gets a bit of getting used to but is a great feature once you have practised with it.
