Create a one of a kind exterior lighting design using a commercial heavy duty SPT-2 stringer this holiday season. This 1,000 foot stringer has 2,000 intermediate sockets spaced 6 inches apart on green wire for screw-in C9 Christmas light bulbs. These stringers can be used with C9 incandescent, C9 retrofit LED, and G50 globe shaped bulbs. UL listed for indoor/outdoor use, the lead length is 12 inches and there is no end plug, so length and plug position are your decision. Let your imagination go wild this holiday season with lighting design possibilities!
