This is DiveRite's 10 watt full spectrum MR11 Standard HID (High Intensity Discharge) with a 13 degree beam and a 12V Nickel Metal Hydride rechagrible canister battery pack. The reflector is adjustable to focus the beam. This light rocks!!!! It came with this fully padded Storm Case!
The beam of this light has absolutely no reflection rings, just a nice solid glow with a smooth concentrated centre beam. It works excellent as a strobe for SC's U/W camera.
With the introduction of SCUBA Crunch's Buddy Badges, this light rarely gets used anymore. When it is, it gets tied to his tank during night dives to assist his buddy in locating him easier. SCUBA Crunch much prefers an un-intrusive red glow to those tank lights with white, yellow or flashing beacons.
This is Underwater Kinetics UK C-4 dive light. It uses 4 'C' size batteries and has two bulbs ready to go.
