Quick Overview

Why does BRS recommend this?

The owner of BRS uses these lights on his personal tank. Kessil produces their own Dense Matrix LED chip which gives them ultimate control over spectrum of the LED chip and the quality. They can be used with or without a controller and give a very natural metal halide shimmer. We find the A360W-E LED lights to have more than enough power for most tanks up and over 24" deep, and with the different mounting options available they are easily adaptable to your tanks lighting needs.

Now amazing shimmer with a controllable LED, we can't help but be impressed with the natural looking lighting effect produced by Kessil LEDs. They produce an amazing shimmer to rival a metal halide and you can even see the shadows of fish swimming over the sand - just like in the ocean. Kessil has put years of research into their LEDs creating a Dense Matrix LED which tightly packs the LEDs onto one chip with numerous colors and numerous wavelengths of light.

  • Kessil Logic™ - Adjust color on one channel and intensity on other channel

Product Questions

How many of these would you recommend for a 220 gallon sps tank
Question by: Ryan on Apr 24, 2016 11:55:00 PM
Great question!
The A360 will ideally be over a 24" x 24" area maximum for good SPS growth. Depending on the length of your tank 3-4 of the lights would be recommended.
Answer by: Connor (Admin) on Apr 27, 2016 2:28:00 PM
What kind of Kessil would you recommend for the biocube 29 gallon tank? Mainly lps and softies. Thanks
Question by: Kasmine on Nov 7, 2016 7:00:00 AM
Thanks for reaching out to us! I would say that one A360W Tuna Blue would be plenty of light for your Biocube! :-)
Answer by: Randy (Admin) on Nov 7, 2016 5:52:00 PM
Hey, do I have to hang these off the ceiling? Also how many FOR a 125 72x18x22. Thanks
Question by: Anthony on Nov 7, 2016 7:12:00 AM
Hey there, thanks for reaching out to us! At a minimum, for full coverage and ample PAR, I would recommend at least 5-6 of these fixtures for your 72" tank. As far as hanging options, I'm sure you could find a way to hang them from the ceiling, however Kessil does have some pretty slick hanging options available. See links below. :-)
Answer by: Randy (Admin) on Nov 7, 2016 6:16:00 PM
Hi. I have a mixed SPS/LPS 66 gallon tank (32L x 24D x 20H)? Would I need to use the 160w or 360w? How many units would I need?
Question by: Khurram Zaveri on Jan 15, 2017 12:07:00 AM
Hey there, for that size of tank and for the corals you want to keep, you will need at least two A360W for proper penetration, spread and PAR.
Answer by: Randy (Admin) on Jan 16, 2017 10:11:00 AM
Would this light be overkill for the Red Sea reefer nano? Would you recommend different lighting for that tank?
Question by: Collin on Jul 29, 2016 11:35:00 AM
Hi there,
A single Kessil A360We LED will be a perfect fit for a Reefer NANO tank. Between the ease of mounting, controlling, and the overall look and spread of the light emitted that would easily be one our top choices to light that tank when it comes to LED’s.
Thanks for the question and if you have any more just let us know.
Answer by: Charlie (Admin) on Aug 1, 2016 8:58:00 AM
greetings have a 150 gall with centerbrace 72''long 18 1/2 ''wide and 26''deep, how any of the 360's will i need, i want to run a reef and fish tank with a few soft corals
Question by: james washington on Dec 5, 2016 3:17:00 PM
Great question! At minimum you would need four, but you may find that creates some shadowing between the lights and on the edges. For full coverage, I would look into 5-6 of these lights. :-)
Answer by: Randy (Admin) on Dec 20, 2016 3:46:00 PM
I have a 5ft long tank. How many of these light will I need to grow spa corals?
Question by: Aaron Miller on Feb 2, 2017 8:56:00 AM
Great question! For even spread and maximum PAR, I would recommend at least four of these lights! :-)

Answer by: Randy (Admin) on Feb 2, 2017 10:56:00 AM
I have a 60" FOWLR tank that I'm setting up and wanted to know if I can get away with using 2 spaced out at 15" and 45" With the possibility of adding a 3rd after a year? Tank is 60L X 24W X 21H
Question by: Marcus Lewis on Jan 24, 2017 3:52:00 PM
Hey there! Since you are not supporting coral with the light, then starting with two lights on that size of tank shouldn't be a problem at all. You will, however, have some significant shadowing in the middle of the tank depending on how you space them. Three would be the best option for sure! :-)
Answer by: Randy (Admin) on Jan 28, 2017 7:43:00 AM
I have a 210 gal tank with the following dimensions: 18"W x 72"L x 24" H
Should I get the narrow angle or the wide angle model?
Question by: Chaminda Fernando on Jun 18, 2016 8:27:00 AM
Great question! For maximum penetration and higher PAR at the bottom of your tank, you would want the narrow angle. If you want more spread, but less PAR at the bottom, you would use the wide angle. :-)
Answer by: Randy (Admin) on Jun 29, 2016 4:38:00 PM
I have the Kessil A360W-E Tuna Blue LED Aquarium Light -which I purchased 6 months ago for a salt water tank.
After a great deal of problems with the tank, I have converted to a fresh water tank. Is there any parts or bulbs I can
use to convert this light to fresh water?
Question by: Pam Donahue on Jan 25, 2017 10:26:00 AM
Hey there! Unfortunately we do not offer any replacement or conversion parts. You may try reaching out to the manufacturer to see if changing out that LED is possible. :-)

Will this work for my 20 gallon nano tank? Looking to put sps and lps in it
Question by: Devin Maldonado on May 30, 2017 3:05:00 PM
The A360 is a great fixture and should be more than capable of supporting a variety of corals in your 20g tank.

Have a great day!
Answer by: Zack (Admin) on Jun 7, 2017 3:16:00 PM
Would this light work on a 32x24x20 mixed reef tank or should I go with 2 tuna blue A160We
Question by: Dave on Jul 19, 2016 10:21:00 AM
Hi Dave,
A single Kessil A360 would be lacking in light on that size tank. We wouldn’t really recommend that light for any tanks wider than 24” at most. For a 32” long tank you would definitely want two of those to get full coverage and have minimal shadows.
Answer by: Charlie (Admin) on Jul 19, 2016 11:07:00 AM
Will Kessil ever allow you to adjust the shimmer?
Question by: Stumpy the Parakeet on Jul 4, 2016 9:07:00 PM
That is a great question!
The Kessil A360 lights can have their spectrum and intensity controlled, but the shimmer is not controllable. The new AP700 LED has magnetic diffusers that will lessen the effect of the shimmer, but unfortunately they are not available for the A360 lights. Some people have managed to create their own diffuser using different intensities of semi-translucent clear plastics and then getting creative on attaching them to the light.
Answer by: Charlie (Admin) on Jul 7, 2016 9:16:00 AM
Do these have a low intensity setting to replicate moon light in the evening?
Question by: Jeremy on May 21, 2017 3:18:00 PM
Currently the Kessils have a limited range on the intensity, and while they can get fairly blue, they don't quite hit the same actinic-only spectrum that most people expect in a dedicated moonlight. For this reason, most people wanting moonlight effects end up adding on a small dedicated accent LED.

Have a great day!
Answer by: Zack (Admin) on May 23, 2017 3:37:00 PM
I was wondering if you would recommend a160 or a360 for a 72"x24"x24" 180 gallon and how many. Or is there another light that you would recommend.
Thanks so much for your help.
Question by: Mike Harmon on Jun 23, 2016 2:15:00 AM
Great question!
We recommend 3 of the Kessil A360's for best performance. Feel free to let us know if you have any further questions!

Thinking about buying this lighting scheme, how many for a 180g tank (want to keep SPS) 72"x24"x24"
Question by: Steve on Jul 22, 2016 8:49:00 AM
Hi there,
For a 180g tank we would suggest starting out with 3 Kessel A360We units and once the corals start to grow out a bit more, you may find that you need more lighting to cover up the shadows that the coral growth has created.
We would suggest looking into adding a couple T5 lamps to help even out the coverage in an SPS dominant tank since 5x A360 units can get pretty expensive.
Answer by: Charlie (Admin) on Jul 22, 2016 3:54:00 PM
Hello I have the innovative marine nuvo 40 and was thinking of this light for my tank. Softies and lps would it work well with good coverage?
Question by: Shane Phillips on Jan 11, 2017 7:43:00 AM
Great question! For LPS and softies, this would be a decent fixture for you. The PAR on the outer edges of the tank will drop off significantly though. :-)

Kessil A360N/A360W Manufacturer's Manual


Dense Matrix LED

Kessil has spent millions of dollars and five years researching a different approach to LED. Instead of individually wrapped LED chips, Kessil tightly packs them together. This results in blends of different light wavelengths before they leave the light, providing uniform color throughout your tank. The single light source eliminates the spotlight effect, effectively spreading the light over a wide area.


Kessil Logic™

The new proprietary Kessil Logic™ is featured on the A360 LEDs. It is a unique form of spectral intelligence developed for precise color blending and optimal coral growth. Before you could vary the light intensity of two different channels to find the desired color and intensity mix. Now users can select the perfect spectrum and color with one knob and then adjust the intensity with the other boosting the light output at both ends of the spectral tuning range by as much as 30%.

  • 3 lights = 2 DEAD in 2 Years. By Gary on 9/10/2017

    I purchased 3 of these lights when I switched to LEDS, March 2015.
    Within the first year..., one of the lights quit. After a lengthy back and forth with customer service, (via email cause they wont answer the phone), they sent me a replacement.
    Just past the two year mark.....the second light burned out. Customer service said it was out of warranty and for a $100 fee, they would look at the light to diagnose it. The results of the inspection states the "fan quit working," and "several circuit board burnouts."
    So...., there solution was.... for me to buy a replacement light for $290......and they would wave the $100 inspection fee. If I choose to go with a different, more reliable light, I still have to pay the $100 fee.
    For a company that touts these lights that they will last thousands of hours......they don't hold up worth a crap and there customer service is even worse.
    3 lights = 2 DEAD in 2 Years.
  • Kessil makes quality products By James on 5/29/2017

    I think these lights have really exceeded expectations. Kessil make great lights and the 360 performs like a champ.
  • Great LPS light By Jwarne on 5/17/2017

    Great light with so much control! Perfect mixed reef light with amazing par spread. I would 100% get the kessil controller with the purchase of the light.
  • Worked great for 3.5 years By Richard on 5/13/2017

    Had no problems with two of these for 3 and a half years. First a few months ago one of the power supplies stopped working. No problem. Contacted the manufacturer and got a new one for $25 I think. Now one of the lights stopped working completely. I can measure the power supply is putting out 19V, but after I plug in the light the power supply overloads and shuts down. So, the light is bad. The second light is still working, but the fan stopped working. probably my fault. I took it apart and found it was pretty loaded with creep and dust. I highly recommend blowing these out more often. But, I was able to find a replacement fan at for $3.49. I can easily swap that out.

    Over all I'm very happy with the craftsmanship of this light and the appearance. I am here to buy a replacement for the one that stopped working.

  • Great for growth and color By Andrew on 12/3/2016

    Been using these lights for awhile now and can honestly say that these are one of the best LED lights on the market. Colors are unbelievable and growth is great as well. I switched from PC to these and I remember my coral responding very well and still are. Love these lights.
  • Just Installed 4 of them over my 42" tall tank By CrazyDiamond on 11/29/2016

    Easy to install - using kessil controller which is really nice & easy to program - nice intensity and color spectrum - hung about 8-10 inches above water level from ceiling - good shimmer from returns generating surface agitation - light penetrates all the way to sand bed - I have some shadowing which I will try to eliminate with t5's - but all in all these
    really make the tank look great - tank is 8ft long, so may have to get one more or raise lights to widen the spread
  • Absolutely spectacular light. By Zachary on 11/14/2016

    I just recently got this light and paired it up with the Kessil Spectral Controller and Kessil Goosenecks and I could not be happier. The light itself is fantastic. Easy to control, the color blending and the shimmer that these lights give off are absolutely stunning. I currently have one over my tank now and I will definitely be getting a second one for my mixed reef tank. Just need to save up a little bit as these lights do have a high price tag to them. But it's totally worth it!
  • Patience hasn't paid off By Jason on 9/8/2016

    I have 6 A360we's over my 8 foot tank for almost 2 years now and am finally throwing in the towel. I have literally done everything to try to make these lights successful. I bought a par meter to fine tune the lights. I have perfected my water parameters and even sent it to Triton. I added 4 rows of t5's for supplement which has drastically improved everything but now I have a t5 aquarium with LED supplement. I just can't achieve the same growth as seen as others in the reef club using different LEDs. Sure I get growth but not on the level as others. Most of them don't need t5 supplements. Now one of the lights is starting to have mechanical problems and I just don't have the patience any longer to keep investing money in a poor choice. It really saddens me because I fell in love with these lights and thought they were so awesome. I have had numerous people over to see if they can find something I am missing. Every conclusion so far has been these lights just don't pack enough punch to get the results I'd like to see and now I finally agree with them. Farewell Kessil. I think I will be switching to the rapidled corona or reefbreeder photon v2.
  • Best light ever By Lance on 8/18/2016

    This was an upgrade from CF bulbs. Now I can have SPS and clams. The shimmer is amazing. This light has turned my 30 gallon nano tank into the focal point of my living room!
  • Lights look great for the little time that they work By Tj on 7/1/2016

    Too expensive for lights that work for about a year and then you start to have problems with, mine keep going out every couple of days and i have to unplug and replug them to get them started again, they do look good and grow coral pretty good but their are better long term options on the market, im thinking of trying out the new photon V2
  • Awesome light By Ricky on 6/15/2016

    I had cheap LEDS before I purchased these lights. Purchased these about 6 months ago. Only draw back I have had is an algae bloom form the change of lights which I mostly corrected, The second is i supplemented with T-5 to fill in the shadows. Noticed the lower half of my larger SPS colonies was fading. Corals all seem happy now.
  • Kessil lights r great By big money on 3/10/2016

    I've been using these lights kessel360w for 2yrs on a 180gal tank.I've never had any problems growing anything with these lights..I bought 1frag of hammers an 1frog spawn frag 1yr ago an now the hammer has about 30 heads an7 drags off of it an the frog spawn has 25or more heads haven't dragged it cause it looks amazing.if ur having problems growing corals you might need to do more water changes.I don't rely on chemicals just sully on water changes an use salinity salt an rotate with reef crystals salt.I love the lights an my corals do to makes taking care of my tank easier.
