Get your pool or water feature party-ready with the Sunnydaze Decor Floating Multi-Color LED Solar Lights - Set of 4. These playful floating lights are crafted using waterproof plastic. Solar panels gather energy when they’re exposed to bright sun. When these lights are fully charged, they’ll deliver colored light for six to eight hours. These floating globe lights don’t open, so the rechargeable batteries are not replaceable. Your set includes four different bulb colors.
