Enjoy the beauty of butterflies day and night with the Smart Solar Butterfly Solar Light String - 20 Color Changing LED Butterflies. This solar-powered decorative light string features 20 energy-saving, multicolored LEDs with translucent covers shaped like butterflies. It automatically illuminates at night, adding a lovely glow to shrubs, patio umbrellas, railings, flower beds, and more. It can be placed even in shady spots because the separate solar panel can be positioned elsewhere in the sun. These solar lights provide up to six hours of illumination when the replaceable, rechargeable Ni-MH battery (included) has been fully charged by the sun.
