Designed for use with 15-watt A15 or S14 light bulbs, this commercial quality patio light stringer is 102 feet in length, and features 50 suspended medium (E26) base sockets with an 8 amp 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. They're perfect for use as patio lighting, on awnings and porches, and even across the backyard. Incompatible with 7.5-watt S11 bulbs. Bulbs not included.
