The Smart Solar Hummingbird Solar String Light doesn"t chirp, flutter, or fly, but it does cast a golden glow. Drape them on trees and shrubs or hang them from patio umbrellas, pergolas, deck railings, and doorways. These string lights feature 20 energy-saving, multicolored LEDs with translucent covers shaped like hummingbirds. After absorbing the sun all day, these solar-powered lights automatically illuminate at dusk. They provide up to six hours of illumination when the rechargeable Ni-MH battery (included) has been fully charged by the sun. You can even place them in shady areas because the separate solar panel can be positioned elsewhere in the sun.
