C9 Christmas light spool-500 Foot, 9-inch Socket Spacing, White Wire SPT-1

Skip the middleman in the big box stores who is choosing the bulb style and color of your Christmas light strings and purchase the style of cord used by professionals across the country to outline roofs and walkways.

This white C9 (E17) spool is part of our collection of cords used to make traditional C9 Christmas light strings featuring E17 (intermediate) sockets spaced 9 inches apart. (That's our most popular spacing.)

This cord is constructed using commercial-grade 18 AWG wire with SPT-1 insulation. Rated at 10 amps and wired in parallel, this spool can be cut to fit your project.

You'll need 666 bulbs to fill every socket in this cord. Cord must be cut to limitations based on light line burnout and your breaker ratings. We suggest that you purchase 10% overage for glass bulb installation.

Don't forget that these cords are not only for Christmas. Fill them with G40 or G50 glass or LED bulbs all year long for parties and special events.

These cords are rated and warranteed for 90 days of normal seasonal use.

Common sense electrical precautions

Do not install more than 250 continuous feet of this Christmas light spool regardless of bulb type. Even if you are using LED bulbs, do not exceed 250 feet in a single string/run of cord. That is the line-limit specification of 18 AWG wire. If you are using incandescent bulbs, your maximum run is determined by the wattage of your bulbs. Do not exceed 1000 watts for a normal household breaker.

Do not exceed 80% of the current rating for your breaker or a max of 10 amps for any run of light or combination of lights. Consult with a master electrician for verification of all electrical figures.

Never strip this cord and wire-nut the end wires together. Ever. Don't ask us why we have to tell you this. Just ask an electrician if you have any questions about installation. We're sorry we have to mention this.
