Each of our solar lights contains faceted acrylic beads that reflect and refract the cascading color changing LEDs for a remarkable light show. Wonderful to hang in a window, or for patio or garden display. Each is powered by a solar panel at the top which charges the lights by day and automatically illuminates when dark. Each hangs on a 10" cord. On/off switch included. 4" long x 3-1/4" wide.
