Why the Kessil A360XE Tuna Blue Is a Game-Changer for Reef Lighting

The Kessil A360XE Tuna Blue doesn’t just follow up on the success of the A360X—it leapfrogs it. With brighter output, improved color mixing, and finer spectrum control, this next-gen LED fixture was built for serious reef keepers who demand performance without the clutter. Whether you're dialing in SPS-dominant tanks or creating that “underwater sunrise” vibe, the A360XE keeps your reef lit with stunning clarity and shimmer.

Kessil A360XE Tuna Blue - Brighter Output, Smarter Engineering

Let’s talk about brightness. The A360XE Tuna Blue uses upgraded thermal management and next-level LED chips to produce 15% more light than its predecessor—without pulling extra watts. It’s efficient, punchy, and powerful where it counts.

Notable improvements:

• Denser LED array for ultra-smooth color blending

• Improved heat dispersion for longer performance lifespan

• No “disco ball” shimmer—just clean, even light spread

• Covers tanks up to 24" x 24" (20" x 20" for SPS tanks)

Kessil A360XE Tuna Blue: Designed for Precision and Simplicity

The Kessil engineering team wasn’t playing around.They were able to manage fitting more chips into a smaller space, creating a light fixture source that copies natural sunlight. This means PAR penetration reaches deeper parts of your tank for better overall lighting.

• Built-in Tuna Blue spectrum for reef coloration

• Added red, green, violet, and indigo channels

• Seamless wavelength blending from a single source

• Full shimmer effect without needing a diffuser

Light Control, Your Way

The Kessil A360XE Tuna Blue doesn’t believe in one-size-fits-all control. Whether you're a plug-and-play type or a full-spectrum fine-tuner, this fixture offers multiple paths to perfect light.

Control Options:

• Onboard Knobs – Quick access to color and intensity

• WiFi Dongle (sold separately) – App-based control from your phone

• Spectral Controller X (sold separately) – Touch control and manual programming

All options connect through K-Link, so you can sync multiple lights while still programming each one independently. Think of it as lighting with a brain.
