This product is designed to provide years of operation, using the light of the sun, and utilizes LEDs (Light-Emitting Diodes) that never need replacing. Simply assemble and place your solar post lamp or lantern in a shade-free area, where the solar panel received direct sunlight for at least 6 hours a day. Easy to set up, no electrical wiring required. It provides brightest output and great appearance to your driveway, walkway or other areas outside your home.
