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.
