Kessil Tuna Blue Aquarium Light. The Kessil® A360NE Tuna Blue LED light is a new edition of LED lights for reef aquariums, which optimally promotes coral growth and coloration, and gives it a magical shimmer. Thanks to Kessil® Logic™ technology, the Tuna Blue light generates constant energy, which contributes to consistent coral growth. The spectrum of the Tuna Blue LED light can be adjusted from deep ocean blue to sky blue. A special blend of UV rays promotes coral growth and coloration in the aquarium. The Kessil® LED lights add an incomparable shimmer through the light reflected from the water surface in the aquarium. A sophisticated thermal management system ensures a long lifespan and maximum efficiency of the light. The Tuna Blue LED aquarium light features a wide range of color control features with countless mounting options, while maintaining the efficiency of the basic spectrum. It can also be used to simulate daylight, dimming effects, and moonlight. With the Kessil® A360X Narrow Reflector, available as an optional accessory, the intensity of the central light beam can be increased by up to 300%. This results in better light concentration, so that deep aquariums, in particular, receive more light near the bottom. The contrast, depth, and dynamics of the aquarium are all improved. The tried-and-tested Tuna Blue light spectrum was a key feature of the previous model, improving coral growth and coloration. In addition to this popular spectrum of the Tuna Blue LED light, aquarists can use the new Spectral Controller X or the Kessil® WiFi device (available soon) to add other colors such as red, green, violet, and indigo (purple) for a more precise color spectrum. The A360NE Tuna Blue LED light measures 114 × 101 mm and weighs only 520 grams. The spectrum is indicated by the following colors: from deep ocean blue to sky blue. Power supply: 100-240V AC (input), 19V DC (output). Power consumption: 90W maximum.
