Black Diamond ReVolt
$60, 3.5 oz. (including its three rechargeable NiMH AAA batteries)
Max burn time: 12 hours with rechargeable batteries, 70 hours with alkaline (triple-power LED); 190 hours with rechargeable batteries, 300 hours with alkaline (single-power LED)
[Note: See my review of the updated, 2017 version of the Black Diamond ReVolt headlamp, which replaced the version reviewed below.]
One of the few downsides of backcountry travel is the volume of alkaline batteries we burn through and throw away. So the first thing that attracted me to the ReVolt is that it’s rechargeable. Then I discovered that this headlamp not only treats the environment well, but it’s powerful, versatile, and pretty darn light and compact—an all-around winner.
