Coverage
The newly designed optics along with the latest generation Dense Matrix LED array provide a broader delivery of light and eliminate shading.
Spectrum
The well-known Tuna Sun spectrum has been proven by its users to promote plant growth and enhance coloration. With Kessil Logic™, it ensures consistent power output and plant growth across the tunable spectrum.

Shimmer
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.
Penetration
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).
Color Mixing
Different wavelengths are seamlessly blended within a single LED array, emitting uniform color across the coverage range.
Full Color Spectrum
In addition to the popular Tuna Blue spectrum, users can add in Red and Amber by using the new Spectral Controller X or the coming Kessil WiFi Dongle.
