A headlamp that mounts to your bare head (with a headstrap, of course) or to your bike helmet. Also functions as a flashlight, a lantern, or a handlebar-mounted bike light.
With 250 lumens, it has plenty of light for an urban commute, and you can take it camping with you on weekends and use it as your flashlight and reading light.
See the road, the trail, the inside of the tent, and the bottom of your panniers when you're looking for your missing lip balm. Great for commuting, camping, and dog walks after dark. Runs on a Li-ion battery that charges from your computer's USB port--or any other powered USB connection such as an adapter for a 12v car outlet, or an Xbox 360.
This specific model only includes the headstrap, other accessories for this light are sold separately.
