When standard LED lighting is too intense, use this specially calibrated multi-color mini LED Christmas light set. The bulbs feature sealed construction with a replaceable plastic cap that will not fade because the LED emits the same color as the cap. The 50 bulbs are spaced 6 inches apart on 25 feet of green wire making them ideal to decorate Christmas trees, interior trim, and fence lines. UL listed for indoor and outdoor use, you can safely combine up to 60 sets end-to-end. Now you can combine the traditional look of incandescent with the energy efficiency of LED technology.
