Add a color-changing LED light stick to your aquarium to create the ultimate GloFish® environment! The GloFish® 10-Inch LED Light Stick includes white, blue and magenta LED lights for aquariums up to 20 gallons and can switch between 4 light modes. With white & blue lights, the vivid colors look great with any décor and fish. Blue lights make GloFish® décor and fish fluoresce even more brilliantly. Magenta lights make all GloFish® fish magically fluoresce, but look especially brilliant with blue, green and purple colors. To make any aquarium a GloFish® aquarium, quickly install the light stick by clipping it into the front of the aquarium frame. Add the universal use light stick to any framed aquarium. It works with light hoods or glass canopies with a rectangular shape. In the box, you’ll also find a frame clip, cord routing clips, light switch, low-voltage transformer, hanger for drip loop and safety manual.
