The aquaufo 90-watt led aquarium light delivers an amazing amount of light with massive 2-watt 6500k and lunar blue leds that penetrate deep into the tank producing eye popping colors and shimmer effects. Aquaufo works right out of the box and there is no need for additional ballasts or reflectors. It emits virtually no heat, so there is no need for additional cooling equipment. Dual power switches allow you to power actinics and whites separately and up to 10 aquaufos can be powered at one time with one outlet.
