These illuminated pathway tiles harness the sun's energy to provide a lighted walkway anywhere in your yard. A matchbook-sized solar panel built into each tile absorbs daylight and automatically illuminates the four inlaid LEDs at night, casting bright, diffused light. The 11 1/2" sq. tiles are made from four planks of PVC that are fashioned to look like slatted hardwood. The modular tiles interlock on any side for customizable, contiguous set up on a level patch of lawn or soil bed, or they can be laid apart like stepping stones. The tiles are 100% waterproof, they'll never rot or fade like wood, and the solar panel is protected by tempered glass, ensuring years of reliable use. LEDs are rated for 20,000 hours. Set of Four. Each: 11" sq. x 1" H. (1 1/2 lbs.)
