This solar gutter light is made for outdoor use, allowing 180° horizontal adjustment to direct light where you need it. It has a built-in light sensor that turns on automatically at night and off during the day, helping to conserve power. With 18 high-quality LED beads, it illuminates areas like decks, backyards, doorways, patios, stairs, garages, fences, and outdoor signs, adding safety for your family and property after dark. The light comes with 2 brackets—you can mount it on exterior walls using the long bracket and screws, or combine both brackets to clamp it to fences or eaves. It uses a large 5.7 x 2.3 in. solar panel with an 18% conversion rate, reducing charging time in sunny conditions, and has an IP55 waterproof rating for durability in various weather. Fully charged, it provides 8-10 hours of runtime, and since it’s solar-powered, no external wires are required. Material: Composite.
