Enhance your outdoor areas with the Feit Electric SL20-10/SOL/V1 20 ft LED Solar String Lights. This string light set comes with a solar panel to power the bulbs without additional electricity. Bulbs give off a warm glow perfect for lighting gazebos, patios, pergolas, restaurants, and more. This non-dimmable set is designed for year-round use, with UL Wet Location approval and sockets that create a waterproof seal around bulb bases. Each set consists of a 20 ft heavy-duty 18/2 black cable, 10 sockets spaced 2 ft apart and 10 energy efficient shatter-resistant LED filament bulbs (plus 1 spare). If one bulb goes out, the rest will remain lit. The solar panel kit can be staked into the ground or wall mounted, for location flexibility. The solar panel charges the included rechargeable lithium-ion battery during the day and powers the lights for up to 8 hours at night. For best results, select a location with full and direct sunlight for at least 6 hours per day to install the solar panel, if installed in a shady area, the battery will take longer to charge, may not fully charge, and may reduce working hours. It is equipped with an on/off override button, allowing you to turn lights off at night, or on during the day (with a charged battery). Each set is powered by a dedicated solar panel, no more worrying about circuit overload or cumbersome power cords stretching from plug to tree. It's your worry-free solution for creating a lighted oasis.
