To get the "professionally" decorated look, it helps to use professional Christmas lights. Our cluster lights are used by many municipalities and resorts. Lights are custom made with 4 clusters of 25 lights separated by a 4 foot lead wire. The lights can be left hanging to form a streamer or rolled into a ball to form a light ornament. Lights come with a wire hanger pre-attached to make installation easier. Four sets can be connected end to end for a total of 16 light ornaments. Each set has four 25 light clusters/streamers.
