These solar lights are designed for outdoor use, featuring an integrated lamp head with a highly transparent acrylic shade engraved with diamond relief patterns for strong light transmission and a wide illumination area. They output bright, cold white LED light with high energy efficiency, using upgraded polycrystalline silicon solar panels for fast charging and a built-in battery that provides 10-12 hours of continuous light after 6-8 hours of charging. The lights are durable, with a waterproof, dustproof, and rustproof design, and include stainless steel stakes for easy installation by simply screwing the battery box into the lamp head and pushing the stake into the soil without any wiring. They create a beautiful glow with a three-foot radius, ideal for enhancing yards, gardens, pathways, and driveways.
