UL SPT-1W Christmas Light Wire 18AWG Outdoor Zip Cord

As the North American holiday lighting market continues to grow, manufacturers and installers require reliable, weather-resistant wire solutions for Christmas light strings and decorative lighting systems.

UL SPT-1W Christmas Light Wire is one of the most widely used parallel cords for C7 and C9 lighting applications. Designed with flexible stranded copper conductors and weather-resistant PVC insulation, SPT-1W provides dependable electrical performance in both indoor and outdoor environments.

Compared with standard SPT-1 wire, the SPT-1W version features enhanced resistance to moisture, UV exposure, and temperature fluctuations, making it an ideal choice for holiday lighting systems exposed to seasonal outdoor conditions. The wire maintains the same 300V rating and flexible zip-cord construction while providing superior environmental durability.

Whether you are manufacturing Christmas light strings, assembling C9 socket lines, or building custom decorative lighting systems, UL SPT-1W wire delivers the performance and safety required by the North American market.
