Pelican 2720 LED Headlamp

Pelican's 2720 LED Headlamp not only outputs up to 200 lumens for 3 hours, but you can turn the light on without touching it. Just wave your hands, and the light comes on. At the low output of 12 lumens, you get 103 hours of runtime on a set of 3x AAA alkaline batteries. There's also a low-level red light setting that helps preserve night vision, a signaling S.O.S. red beacon light, optical 4x magnification for choosing wide or penetrating beam, and variable light output from 100%-10%.
