Sunnydaze Decor Solar Color-Changing Floating Lights for Pools or Ponds (Set of 4)

These solar lights make great additions to any outdoor space - especially pools and ponds. These lights are safe for floating in chlorinated water, and energy efficient, using the power of the sun to charge their batteries during the day. Just place these decorative items in a location with direct sunlight to charge the AA Ni-MH battery. When fully charged, the battery can run for 6-hours to 8-hours, so these lights can illuminate any outdoor space all night long. Please note, the battery is not replaceable due to the unit's inability to be opened. No electricity or wiring is required and each light has a small hole at the top for string or wire so that the solar light can be hung from a tree, post, etc.
