This brand new lighting technique comes to life and casts beautifully patterned shadows, sends shimmering light across any living space, as if moonlight were shining off of the surface of a pool of moving water. The waterproof, battery-operated LED prism unit houses the light source, which creates the appearance of moving light when lit. As you viewing angles change, the patterns shift as well, creating a sense of rhythm and motion. Built for durability, the texture of each lantern creates its own unique light pattern and is waterproof for outdoor use. Perfect for patios, balconies, gardens, and outdoor and indoor spaces!
