Kessils most efficient LED module yet!

The Kessil A80 Tuna Sun has a specially focused spectrum weighted towards a warmer white output perfect for refugiums, planted tanks, and fish-only aquariums where the cool blue output of most reef lights may not be desired.The design of the A80 integrated the body as the actual heat sink for the module allowing for fanless operation making it totally silent. The LEDs in the A80 are packed into Kessil's Dense Matrix array allowing for deep penetration and high power output while giving you control over the intensity and overall color.


Spectrum Range - 6,000K - 9,000K

  • Integrated heat sink
  • Dimmable
  • Kessil Logic
  • Color Tuneable
  • Canopy Mount included
  • Compatible with Spectral Controller
  • Connect multiple with unit link cables



The new innovative design of the A80 integrated the heatsink for the LEDs right into the body of the light allowing for high heat transfer without the need for a fan. The fanless design makes the module virtually silent in operation making them perfect for bedrooms, offices, and other areas where absolutely no noise may be required. 


Dense Matrix LED

Kessil has spent many years developing and researching what LEDs and has their unique array that they build in-house packing numerous diodes into an area no larger than a dime created a nice even blend of colors and producing a very broad spread of light. With such a tight pack of LEDs, the individual colors are thoroughly mixed before the light even leaves the optic lens reducing hot spots and providing uniform coloration throughout the tank.


Kessil Logic™

After many years of R&D, Kessil Logic™ can be found on all of Kessil's LED lights. The A80 allows you to fine tune the overall color and intensity that the light puts out while keeping a spectrum that will be optimal for coral health and growth. With the Kessil Spectral Controller or your favorite aquarium controller that has a 0-10v reference, you can set complete day cycles that ramp up, down, while keeping a consistent output and spectrum.

Product Questions

Would two of these be sufficient for a 45 gallon (36x12x23) freshwater planted tank? With just some medium- lowlight plants?
Question by: Zoie on Jan 7, 2018, 4:57 PM
Thanks for contacting BRS!
Two Kessil A80 Tuna Suns would cover that size of tank nicely. Have a great day!

I plan on running a 2'x2'x12" display fuge with various types of macro algae, would the A80 be sufficient for this type of system?
Question by: Gabe on Dec 4, 2016, 10:33 PM
Hey there,
For a shallow tank like this, the A80 should do a fine job. The H380 will most likely grow the algae the best due to spectrum, but if aesthetics are a concern, the Tuna Sun series can grow plant life quite nicely as well. Depending the distribution of algae in the fuge, you may find that a couple of A80's might be necessary to get the best coverage.

Have a great day!

Would the a80 tuna sun make a good refugium light to grow Chaetomorpha???
Question by: Ken on Nov 24, 2016, 7:16 PM
Great question! Although the Tuna Sun is intended for freshwater systems, it could be utilized to effectively grow macro algae in the refugium. :-)
