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 AP9X compliments the natural beauty of a well-maintained aquarium.

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.

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.

Kessil Ecosystem

With two K-Link and two 0-10V control ports, the AP9X can be easily wired to adjacent Kessil fixtures. Lights in a wired group can then be app-controlled via the AP9X’s WiFi connection. A single AP9X can act as the wireless access point for up to 10 X-Series lights and 20 0-10V lights - giving you total control over all of your tanks.

K-Link + WiFi

Multiple-fixture setups can be controlled via individual WiFi connections or daisy-chained together to access up to 32 lights via one master fixture. Don’t want WiFi signals or interference? Turn off the WiFi and control the AP9X with the built-in manual controls or the Spectral Controller X.

Full Color Spectrum

In addition to the popular Tuna Blue spectrum, users can add in Red, Green, and Purple (Violet + Indigo) by using the redesigned smartphone app. This opens up unlimited color combinations for aesthetics while maintaining the performance of the core spectrum.
