Enjoy crisp, piercing illumination no matter where your adventures take you. The main lamp uses a 110-lumen LED to light up the night, and two secondary white LEDs provide an energy-efficient beam for short-range use. The headlamp is also outfitted with two red LEDs, which won't ruin your peripheral vision in the dark. Runs for up to 300 hours on three included AAA batteries. Elastic headband for a snug fit. Wt: 3.4 oz. Colors: Titanium, Bright Green, Matte Black.
