Princeton Tec Byte
$20, 2 oz. (with two AAA batteries)
Max burn time: 146 hours at maximum brightness
If weight is your top priority when choosing gear and you need a headlamp that’s bright enough for most backpacking situations, the Byte is your pick. I used this tiny, water-resistant light on several backcountry adventures, including family trips in the Everglades and Tetons and a backpacking trip in Idaho’s Sawtooths.
