This Signature LED-10MM-BL-150-12V 3/8-inch LED rope light spool offers a vibrant, long lasting and cost effective alternative to traditional incandescent rope light. Thinner (3/8") diameter provides more flexibility for tighter turns or intricate designs. If cutting rope light into smaller sections, use the FT2-L12NA38CONKIT-2W (sold separately) rope light connector kit. Requires a Low Voltage Transformer.
