Beautiful shimmering effect gives your tank a natural, sunlit look rivaling MH. It's like connecting with your own piece of the ocean.

Tunable Spectrum

Independently adjustable color channels enables tuning a preferred color within the spectral range thousands of research and testing hours determined to be the optimal spectral points for coral growth and color.

Color Mixing

Dense Matrix LED™ technology blends different light wavelengths before they leave the light, providing uniform color throughout the tank. Single light source eliminates spotlight effect, spreading powerful light over a wide area.

UV

No matter which spectral point is chosen with the tunable spectrum, proprietary blend of precision UV light encourages coral color.

Design

Different lens options let you decide between maximum penetration or maximum coverage area. Engineered for long life, quiet operation, efficient cooling and maximum performance, all in a compact, low maintenance and attractive design.

Controllability

On/off timing, intensity and spectrum are adjustable with a 0~10V external controller. Lights can also be daisy-chained without an external controller so adjustments to one light control all others.

Kessil Logic™

*Color temperature for reference only, and is not a direct measurement of CCT

Kessil Logic™ enables equal intensity across all spectral points. From Sky Blue to Deep Ocean Blue and everything in-between, Kessil Logic™ ensures consistent illumination throughout the light's adjustable range.

New From Kessil! Externally controllable version of the extremely popular Kessil A350W.

The A360W version has a slightly greater output in the balanced color spectrum setting and a significantly greater output when tuned toward the blue or white ends of the spectrum. Unlike the A350W that has separate controls for the blue LEDS and white LEDs the A360W has one control for color balance and one control for brightness. The A360W also has an Outboard Controller Input allowing you to control both the brightness and color temperature from a Neptune Apex or Reef Keeper 2 Aquarium Controller.  The A360W can also daisy chain up to four units so a single Kessil can control the others or an outboard controller can control up to four Kessil A360W’s at the same time. With the Neptune Apex controller (and I believe the Reef Keeper 2 as well) you can set the light to start with a low intensity bluer light, ramp up during the day to a whiter full brightness, and then reverse towards the evening.
