Superior Illumination

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 AP9X 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 AP9X 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.

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.

X-Unleashed

Use Kessil’s newly redesigned smartphone app to arrange groups, set schedules, add special effects, and customize colors.
