The Interpet LIFE LIGHT Color Change LED Light adds extra color to your aquarium. Make the most of the rainbow color cycle or use the inline controller to choose your favorite color: blue, purple, pink, red, green, yellow or white. These flexible color change LEDs are fully submersible, easy-to-use, low voltage and incredibly efficient. Either fit them onto your aquarium hood or use the suction cups to place them underwater for a completely different underwater lighting effect.
