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.
