Compact and ready to go, this light never needs batteries. Cranking restores the rechargeable NiMH batteries to their charged state. The Nichia LEDs are bright, virtually unbreakable and never need replacing. Also, the light features a quick to use carabiner clip and the crank operates in either direction. This light is an excellent solution for extended power outages and situations where the light will be stored for a long period of time.
