It starts with a unique dual power electronic circuit to control the matched pair of 5-watt white LEDs. Polarized battery contact plates make it possible to interchange individual battery cells and rechargeable packs as well as prevent potentially dangerous reverse battery insertion. The rubber lens guard, non-breakable locking switch and interchangeable handles are examples of diver hardened construction throughout. The C8 eLED® Plus is the brightest in its class, perfect for piercing the darkness and looking into the great unknown. Special features include: * High insensity 10-watt twin LED module with propriety conductive cooling element shines brighter underwater * Unique optical design unites two high intensity LEDs into one beam with twice the intensity * eLED® circuitry insures constant brightness throughout the battery life * Switch between full and half power to extend battery life * Depth rated to 500 feet
