Description of Black Diamond Icon Headlamp Equipped with a three-watt LED spotlight, four proximity LEDs and eight different brightness settings, the Icon illuminates like no other. Go ahead, burn the three-watt LED all night long—when paired with the NRG Rechargeable Battery Kit (not included), the Icon can be used at full strength without stressing about the money for batteries. When deep in the wilderness on an expedition or multi-day climb, use alkalines and the four proximity LEDs for more than 160 hours of burn time. The Icon’s battery-power meter is dual-purpose: displaying via a green, yellow or red LED either the amount of battery power left or the charging status of the NRG rechargeable battery.
