Black Diamond Storm 400 HeadlampThe 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 our 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.FEATURES:Emits up to 400 lumens on max settingPowerTap(TM) Technology allows instant transitioning between full and dimmed powerBrightness Memory allows you to turn the light on and off at a chosen brightness without reverting back to full powerRegulated for constant light outputCompact, low-profile design uses four AAA batteriesSettings include full strength in proximity and distance modes, dimming, strobe, red, green and blue night-vision, and lock modeMultifaceted optical lens designWaterproof and dustproof: Sealed housing withstands immersion over 1m for 30 minutes (IPX67)SPECIFICATIONS:Weight: without batteries 120 g | 4.2 oz IPX Rating: IPX 67Lumens: 400 (High) | 180 (Low)Max Burntime: 5 H (High) ; 150 H (Low)Max Distance 100 m (highest setting), 9 m (lowest setting)Batteries: 4 AAA (included)
