Description

Kessil's AP9x has redesigned LED chips and optics along with updated, more versatile software and built-in Wifi connectivity. The AP9X represents the combination of Kessil's best features, in a lighting package perfectly suited to a variety of mixed reef systems. The Kessil AP9X is the culmination of all of the recent technological advancements from one of the most popular LED aquarium light manufacturers in the hobby.

Kessil is known for leading in multichip LED light tech. Excellent spectrum-blending qualities and balanced light spread has been something we and many hobbyists have come to count on from them. Kessil's patented Dense Matrix Array packs 55 LED chips into a space smaller than a quarter. With 110 LED chips between two arrays, the AP9X has the best color mixing in the industry - no diffuser necessary and no disco-ball effect! The latest iteration of Kessil’s Dense Matrix array places the chips closer than ever before. More chips in a tighter space results in better color mixing and a brighter single point source - just like the Sun on a natural coral reef. The redesigned optics provide an even light distribution that blankets your aquarium with up to 48” of coverage and can provide useful PAR levels as deep as 30" below the surface. This uniform coverage minimizes hotspots and creates an effect similar to that of a metal halide / T5 combo.

PAR Efficient
PAR measures all visible light, but coral health primarily relies on the 425nm (violet) and 455nm (royal blue) wavelengths. Kessil LED output focuses on these essential wavelengths, prioritizing coral growth and propagation over inflated total PAR numbers. 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.

Spectrum
In addition to Kessil’s signature Tuna Blue spectrum, the AP9X gives you access to the full range of individually adjustable color channels (red, green, purple) which can be accessed via the Kessil app. Kessil Logic ensures that cosmetic color settings won't interfere with the core spectrum, allowing users to dial in their preferred color settings without affecting coral health. The AP9X also includes 395nm LED chips, which emit True UVA light for maximum coral pigment fluorescence.

Sleek yet Robust
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. With design elements inspired by marine fauna, high-performance automotive engineering, and the sun itself, the AP9X 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.

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 32 X-Series lights and 20 0-10V lights.

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

Mounting Options (sold separately)The AP9X can be supported over your tank through a couple of mounting options.

AP9X Mounting Arm

The new AP9X Mounting arm supports the fixture with a single arm, and the integrated swivel joint allows for 60 degrees of vertical rotation and 180 degrees of horizontal rotation.

Hanging Kit

The LED Light Panel Hanging Kit allows you to hang your AP9X from your ceiling or even within your canopy and provides enough cable for an 8 foot drop, as well as the necessary suspension hardware.

Questions about Aquarium Lights & Fish Tank Lighting

What type of aquarium lighting is best for planted freshwater tanks?

The best lighting for planted freshwater aquariums is full-spectrum LED lighting in the range of 6,000–7,500K. This type of lighting provides the essential red and blue wavelengths that plants need for photosynthesis while also producing a natural daylight appearance inside the tank. A fixture such as the Fluval Plant Spectrum LED is specifically designed to encourage strong and healthy plant growth, making it a popular choice for aquascapers and hobbyists who want lush greenery.

What lighting do I need for a reef aquarium?

Reef aquariums thrive under lighting that emphasises the blue and violet spectrum, particularly between 400–500 nm. These wavelengths support photosynthesis in the symbiotic algae within corals and also enhance coral fluorescence, creating the vibrant glow that reef tanks are known for. High-performance LED units such as the EcoTech Radion or AI Hydra deliver the required PAR levels, provide programmable spectrum control, and allow aquarists to mimic natural ocean lighting cycles for the healthiest coral growth.

How many hours should aquarium lights be on each day?

The correct photoperiod depends on the type of aquarium you are running. Freshwater fish-only tanks typically need between six and eight hours of light per day, while planted freshwater setups usually require eight to ten hours to ensure proper plant growth. Marine fish-only tanks also do well with eight to ten hours of light, whereas reef aquariums with corals often need between eight and twelve hours, ideally with gradual ramp-up and ramp-down periods to simulate sunrise and sunset.

Do aquarium lights need to be left on at night?

Aquarium lights should not be left on during the night because fish, plants, and corals all benefit from a natural dark period. Just as in nature, aquatic life requires time to rest, and too much continuous light can cause stress and encourage algae blooms. Some aquarists enjoy using subtle moonlight settings in the evening to view nocturnal behaviour, but these should only be used for a short time and at very low intensity. A consistent cycle of day and night lighting is key to keeping an aquarium balanced and healthy.

Nice searchable website, plenty of stock, reasonably priced next day delivery, well packaged. Slightly more detail would have been nice as I bought 32mm thinking that was the external diameter but I suspect most people buying these items would know that. :)

Such a great service. Bought a fish tank Ciano emotions 150 Pro and it's arrived very well packed just 2 days after purchase. After 2 weeks i had an issue with light power supply which has been replaced straight away after I reported that to customer service. They look afyer customers and always replied very quickly if you have any problem. Strongly recommended!!!
