Different wavelengths are seamlessly blended within a single LED array, emitting uniform color across the coverage range.

The newly designed optics along with the latest generation Dense Matrix LED array provide a broader delivery of light and eliminate shading.

The Kessil shimmer effect gives your tank a beautiful, natural, sunlit look comparable to the shimmer of a Metal Halide fixture. It is like replicating your own piece of the ocean.

Patented Dense Matrix LED technology concentrates multiple LED chips into a single array, creating a powerful and penetrating light source with wide coverage. The maximum penetration can reach 24″ to 30″ beyond the water’s surface for most reefs. Penetration can be further enhanced by using the narrow reflector (optional accessory).

The well-known Tuna Blue spectrum has been proven by its users to promote coral growth and enhance coloration. With Kessil Logic™, it ensures consistent power output and coral growth across the tunable spectrum.
