STORES ELECTRICITY BY DAY TO GIVE YOU A RAINBOW OF BEAUTIFUL COLORS AT NIGHT Now you can use the space age technology of solar cells to create a rainbow of color in your pool at night. As your solar lights float all day in your pool they collect and store electricity in their rechargeable batteries to give off a rainbow of color each evening. The built- in LED bulbs automatically turn on at dusk and constantly change color from green to red, blue to orange, purple to blue and white. They will show their colors for up to 12 hours and the advanced rechargeable batteries will last up to 100,000 hours for years of poolside enjoyment. Our solar lights recharge in partial sunlight and automatically turn off at dawn. Create a rainbow of light in your pool this year with these beautiful floating solar lights. Each light measures 6"W x 3"H.
