The Kessil a360X LEDs are suitable for nearly any freshwater tank or fish only saltwater aquarium. Your planted fresh tank will especially love the a360x. Each light is 30% smaller and 25% brighter then the standard a360 models. With the optional Light Diffusers you can choose whether you want your a360x to be Narrow Angle or Wide Angle. Narrow Angle will reach further down into your tank, Wide Angle will cover a wider surface area.

Kessil reaches a new level of reef keeping with their NEW A360X Tuna Sun LEDs. If you’re looking to have that amazing freshwater habitat, Kessil lights are an outstanding choice. The Dense Matrix Technology tightly packs the LED chips together to achieve high-quality lighting at an affordable price.

Tuna Sun series lights achieve the necessary UV blend to help ensure all of your light demanding planted tank will be happy. As divers we were able to appreciate these lights due to their ability to replicate the “lighting shimmer effect" we see on natural reefs.

Add an A-series gooseneck and Kessil Spectral Controller for easy mounting and outstanding control.
