Each of the 6 acrylic dragonflies on this solar powered garland has a bright color-changing LED inside for a fabulous lighting effect. Each dragonfly hangs down one foot from the 18 ft. long (including 10 ft. wire leading to the lights) cord. The solar collector is 3"H x 6"W x 6"D on a 2 1/2 ft. tall stake and includes 4 rechargeable (by the solar panel) AA NiMH batteries. Dragonflies are 3.5" x 5.5". Place in full sun to charge the batteries in daytime. Auto-on at night. With built-in automatic photocell control.
