There are 50 5MM wide-angle LED lights on this battery-operated strand. The bulbs, also called polka-dot lights, are warm white and there are 4" between each one. The 26 gauge strand stretches a total of 12.5 feet. The 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. They are removeable, however, and can be easily replaced. The built-in automatic timer cycles the lights on for 6 hours and off for 18 hours. It also comes with a switch that can be used to alternate between steady burning and flashing functions. These lights are great for Christmas and Valentine's Day too. 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.
