The Kessil A360X. Low Profile. Advanced Color Control. Smart Communication.

Kessil is well-known throughout the hobby for their low-profile, pendant-style lighting fixtures. Especially for the widely popular 360 series—which has become one of the most sought-out reef lights. Hobbyist love the compact form and substantial output that creates an impressive shimmer inside of the aquarium.

The new X series has an all new set of control features, an even smaller profile and, best of all, more light for your tank with key elements that make Kessil unique & different from any other lighting company: Dense Matrix LED Array, Kessil’s Core Spectrum, and Kessil Logic. 

With newly designed optics paired with the latest generation Dense Matrix LED array, gives a wider spread of light, helping eliminate shading.


Higher Photon Volume Density
A360X has a low profile design with higher light output, thanks to the redesigned, first-class sunflower heat sink.

Advanced Color Control
A360X has more color control, opening unlimited color combinations for aesthetics while maintaining the performance of the core spectrum

Low Dimming & Improved Transitioning
A360X features smoother color transitioning and dimming, including moonlight effect.

Smarter Communication
The new K-Link communication method is an upgrade of the easily plug & play 0-10V, allowing users to network multiple A360X together and set individual groups to run their own programs.

Light Shaping Capability
A360X can be used with optical accessories to shape light, allowing users to modify the look of the aquarium to their liking.

Superior Illumination

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

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.

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).

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, Green, and Violet+Indigo (Purple) by using the new Spectral Controller X or the coming Kessil WiFi Dongle.

Heat Management
Our innovative heat management system enhances longevity and efficiency.
