This Bubbles Celestial Color Changing Solar Lantern is safe for outdoor use. Made of pierced metal and features a weatherproof solar mechanism. Since it's solar-powered, you'll need to place the lantern in direct sunlight to charge the battery. Come dusk, the lantern will automatically illuminate. Color morphing LEDs change from one color to the next seamlessly. Built-in interior discs move to give the lights a moving effect.
