Kessil Logic™

Kessil Logic™ enables near equal intensity across all spectral points from Sky Blue to Deep Ocean Blue and everything in-between.

The Kessil A360 is certified by Neptune Systems as Apex Ready+, and is compatible with many 0~10V external controllers.


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

Select the spectral point you prefer with full confidence your corals are getting what they need for optimal 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 models 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.


On/off timing, intensity and spectrum are adjustable either manually or with a 0~10V external controller. Lights can also be daisy-chained so adjustments to one light control all others.
