C9 Christmas Light Strings and Spools for custom commercial and residential lighting. Screw C9 bulbs into standard E17 sockets and display fun Christmas light themes. Retrofit LED bulbs and incandescent bulbs with E17 bases are designed to screw in and out of sockets for seasonal lighting and full customization. Add zip plugs to create custom lengths, calculate wattage to shop by amp capacity, and choose from spacing options ranging from close 6" spacing to 15" or even 18" spacing for outlining large buildings with lights. C9 light strings are designed to work with any E17 base bulb.
Stringers and spools come ready to use in pre-cut lengths for any decorating project. Available from 25' stringers to 1000' spools with a variety of bulb spacing, custom decorating projects are made easy with C7 stringers. C7 stringers and spools have empty E12 Candelabra bases, ready for any incandescent or LED C7 bulbs. Sockets feature weep holes for water drainage.How can I customize my spools?
Splicing, or cutting stringers and spools, is the best way to decorate custom projects. To splice the wire to a custom length, measure the wire, cut it at the predetermined location, and place a zip plug on the end, creating a female or male plug for outlets or end-to-end runs. Any color or style bulbs from incandescent to LED can be chosen for these spools, so decorating for themes, whether for sports teams, breast cancer awareness, or weddings, becomes easy.What is the difference between SPT1 and SPT2?
Light stringers and spools are available in SPT1 and SPT2 wire, which is the insulation covering the copper wires within the cord. SPT rating refers to the thickness of the wire itself, and how much current it can safely contain. Typically SPT1 wire is rated for 7 amp, and SPT2 is rated for 10 amp. C9 incandescent bulbs are typically powered using SPT2 wire. C9 LED bulbs can often use SPT1 wire due to the reduced power draw in LED technology. When connecting wire end-to-end and using zip plugs for custom lengths, SPT rating needs to remain consistent.
