Kessil AP-9-X LED Fixture
More Light, Less Heat
More efficient LED chips and better heat management result in less energy being lost as heat. This means more light for your reef with the same power draw as before.
Heat Management
The AP9X sports a newly redesigned heat sink and an efficient vortex fan that reduces the accumulation of dust and debris - extending longevity and enhancing efficiency. Such an advanced heat management system also contributes to the low profile form factor.
Our Densest Matrix Yet
Since the development of the patented Dense Matrix LED array began in 2006, we’ve been constantly innovating and improving our technology. The latest iteration of the Dense Matrix array enables us to place the chips closer than ever before. More chips in a tighter space results in better color mixing and a brighter single-point source - more like the sun on a natural coral reef.
Kessil AP9X LED Fixture
Coverage
Redesigned optics provide an even light distribution that blankets your aquarium with up to 48” of coverage. This uniform coverage minimizes hotspots and creates an effect similar to that of a metal halide / T5 combo.
Spectrum
In addition to Kessil’s signature Tuna Blue spectrum, the AP9 features a full range of individually adjustable color channels (red, green, purple) that can be accessed via the Kessil app. Kessil Logic™ ensures that cosmetic color settings do not interfere with the core spectrum, allowing users to dial in a preferred color without disturbing coral health. The AP9 also includes 395nm LED chips, which emit True UVA light for maximum coral coloration.
PAR Efficient
PAR measures all visible light (400-700nm) unweightedly, but coral health primarily relies on the 425nm (violet) and 455nm (royal blue) wavelengths. Kessil LEDs focus on these essential wavelengths, prioritizing coral growth and propagation over inflated PAR readings.
Shimmer
The signature Kessil shimmer effect gives your tank a beautiful, natural, sunlit look comparable to the shimmer of a metal halide fixture - replicating your own piece of the ocean.
Perfect Color Mixing
Our patented Dense Matrix Array allows us to pack 55 LED chips into a space smaller than a quarter. With 110 LED chips in two arrays, the AP9 has the best color mixing in the industry - no diffuser necessary and no disco-ball effect!
Penetration
55 LED chips in a single array create a powerful light source with wide coverage. Maximum penetration reaches up to 30" beyond the water's surface for most reefs. Penetration can be further enhanced by positioning units closer together.
Advanced Dimming
Mimic natural day/night cycles and lunar phases with smooth dimming down to 0.1%—from a gentle sunrise to the faintest moonlight.
Sleek yet Robust
With design elements inspired by marine fauna, high-performance automotive engineering, and the sun itself, the AP9 boasts a sleek, unobtrusive profile with an aesthetically pleasing touch panel. Not just a box of LEDs—the AP9 compliments the natural beauty of a well-maintained aquarium.

Kessil AP9X
I’ve always been a huge fan of Kessil lights and I chose to go with the AP9X over the 360X due the large cross braces on my 180 gallon glass tank limiting my mounting options. The lights look great and I really like the Kessil wi fi app it makes setting colors and intensity super easy! The only downfall I’ve found so far was after testing PAR in the tank with two fixtures it was painfully obvious I will need three fixtures to be able to keep sps and higher light demanding corals. Basically kessil’s claim that one fixture will provide ample coverage for 36” tank is simply not true. I would say 30” for one unit is the max coverage and even that’s pushing it 24x24 is ideal and a video from that other online vendor confirms as much. Anyhow I haven’t seen a lot of detailed owner reviews for this light so I hope this helps a potential buyer get a better idea of what these lights are and are not .Besides that I still like these lights and the shimmer they give my tank even if it’s going to cost more to run them than other led options. At the end of the day it’s an expensive hobby except it and keep reefing !
