Black Diamond Storm 550 Headlamp features a robust waterproof/dustproof housing and 550 lumens of bright light. The compact body is ergonomic, with large, easy-to-use buttons. One button turns the lamp on and off and adjusts the brightness, while the other easily switches between three preset modes (low, medium, and high). The Storm also has red, green, and blue colored night vision modes and peripheral white lighting for close-range activities like rigging rappels on drawn-out descents. The headlamp has our Mode Memory feature, allowing you to turn the light on and off at a chosen brightness. The Storm rechargeable battery is powered via USB-C.
