GloFish LED Light 20 Gallons, Blue and White LED Lights, for Aquariums Up to 20 Gallons

GloFish Light Sticks use a combination of white and blue LEDs to turn any aquarium into a GloFish aquarium. The blue only mode gives GloFish fluorescent fish and GloFish décor an exciting and uniquely fluorescent look. The white and blue mode gives both GloFish and other tropical fish a vibrant look. These waterproof lights attach to the inside edge of the aquarium frame to provide primary lighting to an aquarium, or to add additional lighting to an aquarium. This light is designed for 20 gallon aquariums.
