Let your lighting display sparkle this holiday season with faceted red LED Christmas light sets. The 35 C6 bulbs are spaced 6 inches apart on 18 feet of green wire making them ideal to decorate Christmas trees, interior trim, and fence lines. UL listed for indoor/outdoor use, the lights burn cooler and are ten times more energy efficient than incandescent. Safely combine up to 80 sets end-to-end, and when one bulb goes out the rest stay lit. Give your home lighting display drama with energy efficient LED Christmas lights.
