Beautiful shimmering effect gives your tank a natural, sunlit look rivaling MH. It's like connecting with your own piece of the ocean.

Tunable Spectrum

Independently adjustable color channels enables tuning a preferred color within the spectral range thousands of research and testing hours determined to be the optimal spectral points for coral growth and color.

Color Mixing

Dense Matrix LED™ technology blends different light wavelengths before they leave the light, providing uniform color throughout the tank. Single light source eliminates spotlight effect, spreading powerful light over a wide area.


No matter which spectral point is chosen with the tunable spectrum, proprietary blend of precision UV light encourages coral color.


Different lens options let you decide between maximum penetration or maximum coverage area. Engineered for long life, quiet operation, efficient cooling and maximum performance, all in a compact, low maintenance and attractive design.
