PROFESSIONAL GRADE HOLIDAY LIGHTING ELECTRICAL CORD Make your lighting array work as reliably as the pros. Don't settle for pre-cut lengths like retail stores provide. Make your Christmas lighting array fit your home precisely with custom-cut holiday lighting products like our blank wire (a.k.a. "primer cord"). When you buy professional-grade lighting products from the Christmas Lights Factory, you can "light things up" like the pros. Never have extra cord lengths that dangle over the edge again. Custom-fit your lighting array to your home, yard, fence, patio, storefront, and more. This SPT-1 wire is rated for 8 amps or a 960-watt load. From our professional installation experience, this is generally enough for any indoor or outdoor holiday lighting project. This product pairs well with other accessories like Christmas Lights Factory vampire plugs, and C7 or C9 socket lines.
