Enhance any indoor or outdoor area with this 30 ft. LED color changing string light. Select between between white, red, blue and green color lights with a wireless remote or controller box. Dimming level and color-changing speed are all easily selectable via remote control. Each LED bulb uses just as single watt of electricity - up to 91% less energy than standard incandescent string lights. Set includes a 30-foot heavy duty 18/2 black cord, 15 light sockets set 2 feet apart, 15 decorative clear LED bulbs and 2 spare bulbs. If one bulb goes out, the rest will remain lit.
