The A360X has 25% more light output with 30% less in volume size, equivalent to almost 80% higher PVD than the A360. 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. 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 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. 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 waters 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.
