This is a 50 count, 5MM wide-angle conical, LED light battery-operated strand. The lamps, also called polka-dot lights, are green on green wire and there is 4" spacing between each light. The 26 gauge strand stretches a total of 12.5 feet. Special construction ensures that if one bulb burns out the rest of the bulbs on the strand will remain lit. Both the bulbs and the caps are extremely durable and are much less likely to break than they would with other light sets. Lamps are removable, however, and can be easily replaced if they need to be. The built-in automatic timer cycles the lights on for 6 hours and off for 18 hours. Also comes with a switch that can be used to alternate between steady burning and flashing function. Requires two "C" batteries (not included). Comes with 2 spare bulbs. Please note that these lights are not waterproof and are intended for seasonal use only. Cannot be connected to other strands. Comes packaged in a polybag.
