The rechargeable UK Light Cannon eLED L1 is the latest, and brightest dive light from Underwater Kinetics. Taking advantage of our patented optics technology that combines the light from three LEDs into a single, penetrating beam with minimal spill light, the Light Cannon L1 blows away the competition. Producing a massive 2100 lumens on High power mode, this light is bright enough to light up a reef on a night dive and maintain visibility of your surroundings in the darkness. It's also fantastic for exploring the interiors of wrecks, caves, or other hard to see areas. Our optics technology focuses most of the lumens in the center of the beam, so that unlike other light manufacturers, you actually get the full benefit of the light's lumen rating. Some companies may have over 50% of the light lost as peripheral spill light, so that you're getting a much dimmer light than advertised. At UK, you always get what you need- and what you get helps you see everything, any time of day.
