Quick Overview

Kessils most efficient LED module yet!

The Kessil A80 is perfect for nano mixed reef tanks, most soft coral tanks, and fish only tanks too. 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 - 10,000K - 20,000K

  • Integrated heat sink

  • Dimmable

  • Kessil Logic

  • Color Tuneable

  • Canopy Mount included

  • Compatible with Spectral Controller

  • Connect multiple with unit link cables


Full Details


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.

  • Great for small nano tank By Chris on 8/19/2017

    Bought this to go with my I.M. 10 Nuvo. Seems like a perfect match. Great color and coverage. Down side, have to buy the goose neck. Overall time will tell.
  • works better than advertised By Stumpy the Parakeet on 7/25/2017

    Growing birds nest and pagoda cup corals so far under this little bugger. I have it over my 40 breeder sump with the supplied bracket. depth from light to corals is about 14"-18" away.
    The corals are about three to six inches below the water surface. Will buy another one. Apex controlled for lighting schedule.
  • Looks great. Shimmer is awesome! By John on 7/8/2017

    I just got this light in the mail today. My tank is currently cycle so no livestock to see how it grows corals, but will update in a few months when i can report on that. So far the light looks awesome and produces a nice shine in the tank. Tip: if you order the light after set up like me, make sure you have about two inches of space between the back glass of the tank and the wall you are putting the tank against.
  • This is a amazing lift for any nano cube! By Daniel on 6/14/2017

    I bought this light the weekend that they first had it it has been overall amazing on my JBJ 28gallon anemone cube!
  • Small, quiet and works By Still learning on 4/14/2017

    Put this in my refugium that I'm using to grow out xenia as a nutrient export. I like that it doesn't have a fan to create additional noise. The xenia is doing well and it is also maintaining my temporary frag rack and mangroves until I find a better spot for them.
  • Nice light By Kevin on 3/27/2017

    Currently running this light over a 10 gallon tank at work. The A80 is able to put out more than enough light at any color intensity to keep my SPS and LPS corals happy. Works well for Acropora and Monitoporas, the color of my Acans is really nice when the color is low. The controller is a must-have if you want to grow any coral. The controller allows you to set 6 time-stamps to adjust your intensity/color. It also has a built-in acclimation process that allows you to set a starting power output and adjust the number of days the coral acclimates to the light from between 1-14 days. Very nice product, 10/10 would buy again. I'll definitely be running more kessil's in my house now.
  • Great for a Nano, fish only, or quarantine tank By John on 1/6/2017

    I'm currently running this light over my quarantine tank. Wanted to stick with a kessil but at a lower cost than my a360's (which I'm running on my DT) for a quarantine system. Right now, I have a few softies, LPS and SPS corals in my quarantine, and they all seem to like it. As Ryan says in the videos, due to the spectrum of the kessils, it makes it hard to mess up. I love the simplicity!!

Product Questions

Would two of these be enough for a IM 25 lagoon? I cannot find any par numbers.
Question by: Jeff C on Nov 4, 2016 8:27:00 AM
Hey there! Two of the A80s would not be sufficient enough PAR for that tank. They are geared towards smaller tanks, such as the IM 8gal. :-)
Answer by: Randy (Admin) on Nov 4, 2016 1:45:00 PM
Without a controller (Kessil or Apex) you have to manually turn the unit on/off correct?

Also, with either controller, can you control spectrum from it? Or are you just controlling the intensity?
Question by: Abram on May 25, 2017 5:26:00 PM
Hi Abram,
The A80 Lights without an external controller would need to be manually turned on/off through the tuning dials or the power source. Most people will use a cheap Christmas light style timer to control the on and off function so the spectrum and intensity are always the same when it is on then.
If you use an Apex, or the Kessil controller you can adjust the intensity and the spectrum from the controllers.
Thanks for the questions and have a great day!

Can I control this light using a reef keeper light?
Question by: Larry on Jun 5, 2017 8:36:00 PM
So long as you have the ALC module, you can control the Kessil through the 0-10v dimming port and you'll just need the control cable to plug the light into the ALC. From there, you can control dimming and spectrum.

Happy reefing!
Answer by: Zack (Admin) on Jun 13, 2017 2:58:00 PM
Can two of these work on a 45 gallon long 48' long 18' wide 13'high?
Also the how long are the wires to run a connection for two lights into the spectral control ?
Question by: Adam on Jun 7, 2017 10:35:00 AM
Due to the relatively low output and small size of the light arrays, these are best used on very small tanks and may not serve well on a tank of those dimensions. We would typically recommend a pair of A160's for a mixed reef, or perhaps a pair of A360's for an sps dominated tank. For linking fixtures together, there are link cables available in 6ft or 20ft lengths. The spectral controller itself has a 6ft cable to extend to the master Kessil fixture.

Have a great day!
Answer by: Zack (Admin) on Jun 13, 2017 7:53:00 PM
Would one of these work for a 32 gallon biocube that is 21x21x19 or should I use two?
Question by: David on Jun 7, 2017 11:57:00 PM
I would recommend at least a pair of A80's for a tank of this size, and that would really only be suitable for a low-light setup. If you intend to keep higher light corals in the tank, particularly anywhere near the bottom, I would likely step up to an A160 or for an sps dominated tank even an A360.

Happy reefing!
Answer by: Zack (Admin) on Jun 13, 2017 8:35:00 PM
I have a 72 gallon bow front. Could I do say 3 of these. I have mostly softies with a few lps coral. Won't be doing sps
Question by: Jon Doyle on Nov 6, 2016 12:08:00 PM
Hey there, thanks for reaching out to us! These lights are geared more towards nano/pico type of tanks. I would say that they are going to be under-powered in spread and PAR to properly light your tank. :-) I would recommend at least 2-A360W Tuna Blue fixtures or a single AP700.
Answer by: Randy (Admin) on Nov 8, 2016 4:36:00 PM
Would this work in conjunction with two a160's and a spectral controller. I was thinking of putting this in the middle of the 160s on a IM30L.
Question by: Johnm on Sep 15, 2017 2:40:00 PM
Hey there,

This would likely not be an effective solution. Part of the issue is that the Spectral Controller can only be set to one schedule and set of ramp up/ramp down. Since the A80 is only 15 watts, you may find that you want different intensity settings compared to more powerful options like the 160s.

Answer by: Zack (Admin) on Sep 15, 2017 3:24:00 PM
Hi, I was wondering whether this light could house simpler sps, such as bird nest and maybe some montipora In a IM 10 gallon? Also what is the par numbers as I have not found any?
Question by: Francisco on Nov 6, 2016 1:14:00 PM
Hey there, great question! In a small 10gal tank like yours, I would say that these lights can sufficiently grow easier demand SPS like the ones you mentioned. Unfortunately, we have not given this light our PAR readings test and do not currently have those levels available at this time. :-)
Answer by: Randy (Admin) on Nov 8, 2016 4:40:00 PM
If I have a 10g tank and I want soft coral and lps like zoanthids, candy cane, and hammer coral should I use this light. Right now I have the current USA orbit marine would this light be a nice upgrade or would it be like the same as I have now.
Question by: Kevin Haynes on Dec 27, 2016 9:29:00 PM
Great question! This light is perfect for LPS and Softies in a nano tank that size! One of our employees has that exact setup. :-)
Answer by: Randy (Admin) on Jan 2, 2017 7:29:00 AM
Hey guys! Your thoughts on a couple of these on a 20 gallon long? 30x12x12?
Question by: Sean on Nov 6, 2016 8:04:00 PM
Hey there, thanks for reaching out to us! I would recommend two of these lights for a 20gal Long tank. :-)
Answer by: Randy (Admin) on Nov 7, 2016 5:26:00 PM
As far as a price point would this light work well on a refugium 8"x15"? I understand that the Kessil purple is best, but is more than double the price. Thanks
Question by: Nick Scaccia on Nov 7, 2016 10:14:00 AM
Hey there, thanks for reaching out to us! I would say that this could be used as a refugium light, however the spectrum it produces would not the most conducive to growing macro algae effectively. :-)
Answer by: Randy (Admin) on Nov 7, 2016 5:56:00 PM
If I was to put this on my frag tank 12x12x5 would I be able to keep sps in the center of the tank and the lps on the outside ?
Question by: william Duong on Jan 24, 2017 12:45:00 PM
Great question! This light is severely under-powered to utilize outside of a 1gal-15gal nano tank. It would not have enough PAR output to cover your size of tank and adequately support SPS. We have an A80 on a small 5gal nano tank in the office and it is just the right size at 75% power. I would recommend a Kessil A360W Tuna instead. :-)
Answer by: Randy (Admin) on Jan 28, 2017 7:37:00 AM
I'm looking to run both a nano and my main setup. I have A360s on my main setup run off of a spectral controller. Can I slave one of these off of the A360s on the main system?
Question by: Lukas on May 30, 2017 10:37:00 AM
I'm afraid the spectral range on the H series grow lights is different from standard reef lights and will require the H series specific controller.

Happy reefing!
Answer by: Zack (Admin) on Jun 7, 2017 2:57:00 PM
Can I control this with an apex controller? What would I need to do so?
Question by: Aj on Jan 1, 2017 10:23:00 PM
Hey there! You can absolutely control the A80 with the Neptune Apex! All you need is the cable listed below. :-)

Answer by: Randy (Admin) on Jan 4, 2017 3:04:00 PM
Will this grow soft, lps, and sps corals in my ten gallon tank. Also you may not know the answer to this but I currently have the asta lumini for the tank will this keep my corals alive for about a month while I save up for a better this light.
Question by: Newreefer on Oct 8, 2017 7:17:00 AM
Hey there,
Thanks for getting in touch with us in regards to lighting your ten gallon aquarium. I can say that I have personally used this light over a Nuvo ten gallon and was able to grow even a Deresa clam on the bottom. This light should allow for the growth of anything that you would want to have in that ten gallon. For higher light demand critters you may want to strategically place them to keep them in a good area of coverage depending on the length of the tank. Please let me know if there is anything else that we can assist with. Thanks!
Answer by: Tyler Schafer (Admin) on Oct 14, 2017 2:37:00 PM
Will 3 of these work on a 72inx24inx24in tank?
Question by: Daniel on Nov 3, 2016 2:53:00 PM
Hey there! These lights are geared more towards nano and pico sized tanks. Unfortunately, they are far under powered to cover a tank that size. I would recommend 2-3 Kessil AP700s instead. :-)
