Lighting is an important part of your aquarium and is highly recommended for any aquarium set up. Aqua One EcoLite LED Aquarium Light is a must for all aquariums. Not only does it provide a modern, sleek aesthetic appearance to your aquarium, but it is vital for the life within the aquarium, from the fishes to the plants! Comes with a 3 switch cycle that can alternate between 5W, 8W and both. This allows greater control over brightness to suit the environment in your aquarium, and also can save energy if used at a lower watt.
