Light Monkey LED lights are available in 3 different levels of light output: 12 Watt, 20 Watt, and 32 Watt. Each uses a combination of different emitters with specifically designed optics to provide a tight beam for cutting through low-visibility water and promoting effective signaling. Light Monkey has spent ten years developing our LED technology, finding the right combination of LED emitter and reflector to keep a tight beam. Light Monkey's 12 Watt LED utilizes an Osram emitter. In their 20 Watt and 32 Watt LEDs, they are using a Cree emitter with our own custom reflector. The result is a laser-tight center spot for signaling and the perfect amount of spill around the side to give more peripheral light. 6500 Kelvin Color Level 5 - 8600 Lumen Level 4 - 4730 Lumen Level 3 - 2795 Lumen Level 2 - 1000 Lumen Level 1 - 250 Lumen
