Install your Christmas lights this season in half the traditional time, with secure built-in spring-loaded clips. With 180 degrees rotation, you can adjust the lights toward your desired direction. Durable acrylic resin, drain-holes, and weather-sealed sockets prevent damage and withstand the harshest weather conditions. The 100 LED bulbs are energy-efficient, remain cool to the touch, and reduce power usage. Each 66’8-foot strand has plug-ins at both ends, allowing you to link up to 90 strands. These lights will bring a special glow to any holiday, wedding, or birthday and clip securely to branches, rooflines, and railings. The product's compact re-usable packaging makes it extremely easy to store during off seasons.
