Now with a slimmer, more powerful design, the Black Diamond Gizmo Headlamp is a ready-for-anything light that"s useful in more places than you can imagine. From chores around camp to a mellow night hike, the Gizmo"s 3 Single Power LEDs provide up to 35 lumens of brightness as well as dimming and strobe modes. The headlamp also automatically powers off after 2 hours to avoid accidental battery drain.
