The Storm 400 is engineered for epics in all conditions, featuring a robust waterproof/dustproof housing and 400 lumens of bright light. With a new, compact body, the Storm 400 is more ergonomic, and the updated user interface includes a secondary switch for easy mode selection. In addition, the updated optical efficiency not only provides brighter light, but also saves battery life that you can now easily track with a six-setting, three-LED battery meter. The Storm 400 also has three different colored night vision modes and peripheral white lighting for close-range activities like carefully re-racking for the final summit pitch in the dark. The headlamp has Black Diamond’s Brightness Memory feature, which allows you to turn the light on and off at a chosen brightness without reverting back to the default, full power setting. The Storm 400’s PowerTap Technology enables you to quickly and easily access maximum brightness with the touch of a finger.
