Whether you&';re on a multi-day backcountry hut trip, or linking 14ers in a single push, the Black Diamond Icon 700 Headlamp provides a powerful 700-lumen output, making it our most powerful light. We&';ve now updated the user interface by adding a second switch for easy lens mode selection, and improved the optical efficiency, which provides brighter light with more peak intensity, plus you can easily track battery life with a six-setting, three-LED battery meter. Waterproof to 1 meter, it&';s ready for anything, and with red, green and blue night-vision modes, making it versatile for any mission. The removable battery pack can be easily stowed in a pocket to preserve battery life with a cord long enough to reach those deep warm pockets for "polar mode," in cold temps. Finally, the Icon 700&';s Brightness Memory gives you the option to set the light&';s brightness when first turned on, plus PowerTap Technology makes for instant brightness adjustment settings.
