Low Profile. Advanced Color Control. Smart Communication

Kessil A360X LED lights cover more of your tank while blending better than almost any other LED available. Using Kessil Logic, tuning the light for optimal coral growth and coloration is easy since the A360X will automatically adjust to a balanced spectrum for the light color that you want to see. Kessil A360 lights have always been known for their outstanding shimmer effect while maintaining uniform color mixing throughout the aquarium. We have used all types of Kessil LED lights over the years and have been very impressed with their quality, control, and lighting output. 


Recommended Coverage - 24" x 24"


Tuna Blue

Perfect for reef tanks and can produce light that has a rich deep blue all the way to bright natural daylight. Kessil has been tuning the Dense Matrix LEDs to bring out the best growth and coloration in corals. The adjustable spectrum lets you choose the color you want to see, while Kessil Logic ensures a balanced spectrum and power output.



Higher Photon Volume Density - A360X has a low profile design with higher light output, thanks to the redesigned, first-class sunflower heat sink.

Advanced Color Control - A360X has more color control, opening unlimited color combinations for aesthetics while maintaining the performance of the core spectrum

Low Dimming & Improved Transitioning - A360X features smoother color transitioning and dimming, including moonlight effect.

Smarter Communication - The new K-Link communication method is an upgrade of the easy plug & play 0-10V, allowing users to network multiple A360X together and set individual groups to run their own programs.

Light Shaping Capability - A360X can be used with optical accessories to shape light, allowing users to modify the look of the aquarium to their liking.


Superior Illumination

Coverage - The newly designed A360X optics along with the latest generation Dense Matrix LED array to provide a broader delivery of light and eliminate shading.

Spectrum - The well-known Tuna Blue spectrum has been proven by its users to promote coral growth and enhance coloration. With Kessil Logic, it ensures consistent power output and coral growth across the tunable spectrum.

Shimmer - The Kessil shimmer effect gives your tank a beautiful, natural, sunlit look comparable to the shimmer of a Metal Halide fixture. It is like replicating your own piece of the ocean.

Penetration - Kessil's Patented Dense Matrix LED technology concentrates multiple LED chips into a single array, creating a powerful and penetrating light source with wide coverage. The maximum penetration can reach 24" to 30" beyond the water`s surface for most reefs. Penetration can be further enhanced by using the narrow reflector (coming soon).

Color Mixing - Different wavelengths are seamlessly blended within a single LED array, emitting uniform color across the coverage range, and reducing individual color separation to almost nothing.



Full-Color Spectrum - In addition to the popular Tuna Blue spectrum, users can add in Red, Green, and Violet+Indigo (Purple) by using the new Spectral Controller X or the Kessil WiFi Dongle.

Heat Management - The innovative heat management system enhances longevity and efficiency on all A360X lights

Dense Matrix LED - Kessils densely-packed LED array emits more high-quality light than competing fixtures.



Wireless - The Kessil A360X WiFi Dongle lets you control any A360X light without the need of additional cords or hardware. The WiFi Dongle will plug right into the K-Link connector and let you connect directly to the light with any Android or iOS phone. The intuitive app boasts a ton of features that lets you do everything from daily automated programming to manual programming for photoshoots or just showing off your reef tank. 

Hardwired - The Kessil Spectral Controller X is packed with features that let you simulate the natural rise and fall of the sun throughout the day. You do not necessarily need the Spectral Controller X, but adding it to your A360X lights will unlock additional features and modes that give you endless customization of the lights for your aquarium. You can even connect multiple Kessil A360X LED Lights together for larger tanks with the K-Link Cable to create a seamless day-cycle between all the lights.

Product Questions

I remember seeing spectrum settings that you guys recommend with this light in one of your videos, but I can't find it now. Can you tell me what color settings you guys recommend with the A360X? The video called out the overall color setting plus violet/green/red levels.

Question by: John Brady on Jun 3, 2022, 10:29 AM
Thanks for the question! I have linked the video down below for reference. We have a BRS spectrum set to color of 20, violet 100, red 20, and green 0. Let us know if you have any more questions!

Can the apex control these lights
Question by: Peter Massaro on May 18, 2022, 12:53 PM
Hey Peter, thanks for the question. You would NOT be able to control these lights via the apex. You would need to get the wifi dongle or the spectral X controller for them.

Can used in 220v?
Question by: David Diaz Smith on Mar 22, 2022, 10:00 AM
Hey David, thanks for the question! These are sold with a standard US 110v plug.

Are these lights apex compatible to control color and intesity?
Question by: Glenn Davidson on Mar 8, 2020, 5:26 PM
Hi there,

Unfortunately there is no Apex compatibility with the 360x, only the 360WE.

Take care

are they apex compatible?
Question by: Rob on Oct 30, 2019, 10:41 PM
Unfortunately, these are not Apex compatible at the moment :(

I currently am running 3 kessil A360w Tuna Blues. One has recently stopped working. Can I replace it with the 360x? If so can they still all be connected together and operate through the original spectrum controller?
Question by: Michael on Aug 27, 2019, 8:07 PM
Hey there!

The lights can be daisy cahined still but the 360x would not be able to be controlled by the Spectral Controller. You have to have the new controller for the 360x.

take care

Hello, I currently have 4 x T5's on my 4ft 100 gallon FOWLR but looking to upgrade to LED. How many Kessil A360X would I need and also, should I retain the T5's or use LED only? Thank you.
Question by: Jason Moore on Mar 29, 2019, 1:07 AM
Hey there-

On my 4ft 75 gallon reef I use the 48" Aquatic Life hybrid T5 setup with 2 Kessil A360s and absolutely love it! You can certainly get away with just 2-3 kessils by themselves but the hybrid fixture covers each lighting method's weaknesses extremely well (which is why kessils + T5s are on of our most highly recommended lighting combinations for hybrid setups).

Take care!

What is its coverage? one will work for a 30"x20"x20" tank?
Question by: Bruno Hirata on Jan 3, 2019, 7:01 AM
Thank you for reaching out to Bulk Reef Supply! Yes, this light has a spread of 36" x 36" and would absolutely be a good choice for your tank. I hope this was helpful. Please reach back out if you have any further questions!

Do I have to purchase additional k link cables in order to connect my kessils through the spectral x controller?
Question by: Aaron on Dec 29, 2018, 7:58 PM
Thanks for contacting BRS!
The Spectral X controller will come with one K-link cable to connect to one Kessil A360X, but if you want to hook more Kessils together you will need additional K-link cables. Have a great day!

Hello, what mount do you recommend for a rimmed tank? My tank is 125g so rim is thick. Thanks
Question by: Diana Powers on Dec 27, 2018, 3:50 PM
Thank you for reaching out to Bulk Reef Supply! I will link below the Kessil A series goosneck. This is what we would recommend for a mounting option for this light.
