Kessil A80 Review – Tuna Blue LED Light w/ Mini Gooseneck Fully Reviewed

To get the colors of your aquarium popping, and your fish and reef to flourish, you need a solid lighting system.

We tested the Kessil A80 for a couple of months to see how it fared with our aquarium. We have to admit, the results were pretty positive.

We’re highly impressed with the sleek design of this powder-coated aluminum model. The build quality is commendable, and it’s one of the smallest LED light set-ups on the market. The seamless installation is the icing on the cake.

The Kessil A80 Tuna Blue LED Light with Mini Gooseneck is the company’s smallest LED to date. This light is perfect for nano reef tanks. For its size, it’s pretty impressive as it covers a full 24 inches. It comes with a neat cooling system baked in. You can change the color and intensity with ease.

To kick off our Kessil A80 review, let’s take a glimpse at the key differences between Kessil’s leading models.

Tuna Sun Vs Tuna Blue Key Difference

Should you opt for a Tuna Sun or a Tuna Blue, then? It depends on whether you’re running a marine/reef tank or a freshwater/planted tank.

While the Tuna Sun generates a good deal of light, it’s only suitable for small fish tanks with LPS coral. If you have SPS coral, you’re better off with Kessil’s A160 or A360 line.

Kessil A80 Tuna Blue Review

Design and Build

The Kessil A80 is quite heavy. Its high-end passive cooling system doesn’t have a fan, which means it’s completely silent.

This light is perfect for a tank in a bedroom or an office. You’re unlikely to get splash-back or salt creep with this LED.

The Kessil A80 Tuna Blue comes with the following bundled:

  • Light
  • Mount
  • Power adapter
  • Mini gooseneck

The LED light itself includes:

  • Power on/off buttons
  • Color intensity dial
  • Light intensity dial

The body of the light is compact and measures just 10mm across. The design is smooth and the rounded shape is stylish. The LED is made from powder-coated aluminum.

Although it’s small, this model packs the same power as Kessil’s heavier-duty models such as the A160 and A360 lights. It’s powered by 100-240V AC input and 24V DC output.

Like Kessil’s other models, the A80 incorporates a dial to control color. There’s another dial to manipulate the intensity. This new model comes with a 0-10v input for use with Kessil’s spectral controller or third-party spectral controllers.

A mini gooseneck screws into the LED light and attaches to the mount. This gives you full flexibility with placement.

The Lighting

You can expect the same quality of lights as you would with Kessil’s more powerful models. Due to its size, the A80 is better suited to smaller tanks or larger tanks containing only fish.

The Dense Matrix Array incorporates 15 LEDs covering colors including:

  • White
  • Blue
  • Magenta
  • UV

The light itself kicks out 15 watts, giving you plenty of bang for your buck. It’s a great way to brighten up your aquarium so you can enjoy your beautiful, shimmering aquatic display.

The Light Distribution

The Kessil A80 covers tanks between 14” and 24”. If you use the gooseneck to mount the Kessil A80, this will suspend the light at 15”, giving you decent coverage of a shallow reef tank. The light, high-quality lens and reflector maximize a broad spread of light so you can enjoy coverage of 24” at a height of 8”.

The A80 will give your aquarium 24” coverage if you have a large fish-only tank that only calls for low light. This is based on placing the LED between 6” and 8” above the water.


  • With a maximum power of 15 watts, the Kessil A80 generates strong light while remaining economical.
  • The mini gooseneck mount is versatile and allows you to fully customize its setting.
  • It’s small and perfectly formed. Measuring 4.88” across and 0.98” high, the A80 is one of the smallest LED aquarium lights on the market.
  • It’s simple to set up.
  • Comes with two tuning dials, one for color intensity and the other for light intensity.
  • Works well with rimmed or rimless tanks up to 1/8” thick.
  • Passive cooling system so runs whisper-quiet – ideal for a bedroom or office.


  • While the Kessil A80 kicks out a good amount of light, it’s not suited for medium or large aquariums.
  • Does not include pre-programmed settings.
  • Unfortunately, the Kessil A80 doesn’t give PAR readings.

Final Verdict

The Kessil A80 Tuna Blue LED light is small, compact, and remarkably efficient. It delivers ample light for smaller reef tanks or larger, fish-only aquariums.

Its state-of-the-art passive cooling system is deadly silent. This means it fits neatly anywhere you need to sleep or concentrate. The gooseneck mount means there’s no need to suspend it from the ceiling, making installation a cinch.

Its sleek and compact powder-coated aluminum design makes a statement. It’s not bulky or unsightly like so many models glutting the market.

On the downside, the A80 lacks PAR reading. There’s no alarm or timer either. If you like preset weather settings, the A80 isn’t the best choice. That said, the manual tuning dials allow you to dial in your favorite settings with ease.

We rate this model highly due to its affordability. Considering its size, it represents incredibly good value. When you unbox it, you’ll feel how heavy it is proportional to that small form factor.
