This Bulbrite 810002 48-foot commercial light stringer is perfect for outdoor patios and features 15 medium (E26) base sockets with a fused plug for added safety. For additional reinforcement, each suspended socket provides an eyelet for cable wires to run through in order to support the string lights. The socket and the main wire are connected by a suspensor, which lowers the socket to help provide better illumination. With 3-foot spacing, you are able to string up to four sets together with a 1,500-watt maximum for the entire line. Light stringers are perfect for use as patio lighting, on awnings and porches, and even across the backyard. Fifteen S14 bulbs included.
