Using the latest in LED Christmas lighting technology, these light strings are shaped like traditional C9 bulbs but use up to 90% less electricity than their glass counterparts. Wired like traditional Christmas tree lights using 20 AWG wire, their single-body engineering makes them ultra-low current allowing them to be run 100's of feet in series. Rectifiers at the beginning and middle of each set significantly reduce flicker. Non-removable bulbs resist moisture and create a seal against the elements.
Keep in mind that the bulbs on this set of lights cannot be removed or replaced. If you are searching for C9 LED replacement bulbs or traditional 18 AWG Christmas light cords, head over to Christmas light bulbs and cords.
