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
  • Compatible with external 0~10V Controller like Neptune Apex or Digital Aquatics Reefkeeper
  • Compact, pendant design
  • Exceptional shimmer effect
  • Dense Matrix LED - patented design of tightly packed LED
  • Proprietary blend of precision UV light to encourage coral coloration
  • Two Channels for fine tuning of color spectrum
  • Quiet operation
  • Runs cool at high efficiency


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%.

Product Questions

good afternoon, How many of these kessil light would I need for good coverage and par levels for mixed reef tank.
I have 180 gallon 72" long 24"wide and 18" deep I believe. thanks for your input. Im ready to pull the trigger and get some of these from yall.
Question by: kyle huggins on Feb 5, 2020, 2:11 PM
Depending on the type of coral you want to keep, softies only I would go with 4. LPS or SPS you would need to go with 5-6. I personally would do 6.

Take care
Answer by: Thomas Billington on Feb 5, 2020, 2:51 PM
on a 72'' 120 gallon tank would it be better to run 3 wide angle or 4 narrow angle lights?
Question by: Alan Dorich on Sep 6, 2018, 8:08 PM
Hey there!

I would recommend going with 3 of the wide angles!
Answer by: Thomas on Sep 7, 2018, 2:43 PM
I have a tank that's 48x24x16 how many should I use
Question by: Jeremy Reyes on Aug 30, 2018, 2:45 PM
Hey there!

You can use 2 and have the coverage for that tank. I would recommend using 3 if you can.
Answer by: Thomas Billington on Aug 30, 2018, 2:50 PM
34 db reef ready tank size 36x18x12 would this light work??
Question by: Chuck on Nov 20, 2017, 3:48 PM
The A360 will do very nicely, however I would go with a pair to light a tank of this size. For that price range, you may find a single AP700 to be a good option.

Happy reefing!
Answer by: Zack on Nov 24, 2017, 3:03 PM
Will the 360 provide enough light to support RBTAs?
Question by: Mick on Nov 11, 2017, 9:08 PM
In most cases, the A360 lights will be perfectly suitable for RBTA growth. They will probably have more power than you actually need to use too.
Answer by: Charlie on Nov 25, 2017, 9:50 AM
If I wish to grow Chaeto in a refugium tank can I use the Kessil A360W-E Tuna Blue LED Aquarium Light instead of the
H380 Halo II LED Algae Grow Light
Question by: Donald Kozak on Oct 29, 2017, 6:24 PM
On its whitest setting, yes, you can grow chaeto, but the growth rate will not compare to what the H380 or even an H80 could produce. having the correct spectrum to grow algae we have found is very important, and having the correct spectrum will make algae grow much quicker and healthier.
Answer by: Charlie on Nov 18, 2017, 7:31 AM
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 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 on Jun 7, 2017, 3:16 PM
Do these have a low intensity setting to replicate moon light in the evening?
Question by: Jeremy on May 21, 2017, 3:18 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 on May 23, 2017, 3:37 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 AM
Great question! For even spread and maximum PAR, I would recommend at least four of these lights! :-)

Answer by: Randy on Feb 2, 2017, 10:56 AM
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 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. :-)

Answer by: Randy on Jan 28, 2017, 10:46 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 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 on Jan 28, 2017, 7:43 AM
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 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 on Jan 16, 2017, 10:11 AM
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 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. :-)
Answer by: Randy on Jan 11, 2017, 2:11 PM
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 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 on Dec 20, 2016, 3:46 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 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 on Nov 7, 2016, 6:16 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 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 on Nov 7, 2016, 5:52 PM
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 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 on Aug 1, 2016, 8:58 AM
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 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 on Jul 22, 2016, 3:54 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 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 on Jul 19, 2016, 11:07 AM
Will Kessil ever allow you to adjust the shimmer?
Question by: Stumpy the Parakeet on Jul 4, 2016, 9:07 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 on Jul 7, 2016, 9:16 AM
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 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!
Answer by: Connor on Jun 29, 2016, 4:55 PM
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 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 on Jun 29, 2016, 4:38 PM
how many A 360W-E Tuna Blue LEDs do I need for a fusion 50 IM tank?
Question by: Lisa DiMercurio on May 29, 2016, 2:06 AM
How many of these would you recommend for a 220 gallon sps tank
Question by: Ryan on Apr 24, 2016, 11:55 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.
