Solar-powered LED bulbs accumulate and store clean energy during the day to allow 10+ hours of illuminating power at night. Easy assembly and mounting - attach the included stakes, and mount Disk Lights on the ground. The four-corner stake maintains stability and eliminates accidental dislodging of product e.g. during lawn mowing or when pets and children are playing around. Disk Lights can be manually switched off by clicking the switch button located on the underside section of the product. Moisture-proof design ensures that Disk Lights remain unaffected even after a heavy downpour. Our product also does not utilize electricity - an added bonus as far as safety and cost-efficiency are concerned. Durable construction for long-term usage. The metal casing is rust-resistant, lightweight, and durable.
