You'll see stars - even on cloudy nights - with the Smart Solar Garden Solar Light String - 30 White LED Stars. This solar-powered decorative light string features 30 energy-saving, white LEDs with translucent star-shaped covers. It automatically illuminates at dusk, adding a lovely accent to shrubs, patio umbrellas, doorways, 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. Smart Solar Driven by a strong belief in the environmental benefits of solar power, and the realization that consumers are becoming increasingly environmentally aware with an interest in buying solar-powered products, Smart Solar was created in 2003. Based near Oxford in the U.K., Smart Solar has offices in the U.S
