The ultimate in LED lighting specifically designed for the Reef Aquarium Enthusiast! Evolution LED's provide the spectrum many reef keepers strive for a vibrant blue with just the right mix of white to make our corals pop! Providing par readings to support growth to all LPS, SPS, Zoanthids and soft corals rivaling a 250 watt metal halide! Extremely if non-existent heat transfer while still providing the "shimmering effect" halide owners tend to enjoy make the Evolution LED's a must have. Not to mention the "we miss you" card you'll get from your local power provider!!!!
