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.


Total Control

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.

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

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.


Single Arm Mount

The new AP9 Mounting Arm allows the fixture to be mounted with a single arm - the most light spread from a single arm mount fixture on the market. The integrated swivel joint allows 60 degrees of vertical rotation and 180 degrees of horizontal rotation - Allowing you to adjust your light to the orientation best suited for your tank.

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.

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.

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.
