How to Choose

Choose stringer wire length based on your installation's linear footage — measure the full run from the power source to the end cap.

Choose green wire for installations against foliage or dark backgrounds; white wire for white trim and fascia. SPT2 is the heavier grade and is preferred for outdoor professional installations.

Frequently Asked Questions

What is stringer wire?

Stringer wire (also called socket wire) is the insulated electrical wire with included sockets that C7 and C9 LED bulbs screw into. It's the infrastructure component of a C7/C9 installation — bulbs are sold separately and screw in.

What socket spacing is standard for C7 stringers?

Standard C7 socket spacing is 12 inches. This is the most common configuration for residential and commercial C7 installations.

What's the difference between SPT1 and SPT2 wire?

SPT2 is heavier gauge and rated for higher loads than SPT1. SPT2 is the standard for outdoor professional installations. SPT1 can be used for lighter indoor applications.

Can I cut C7 stringer wire to length?

Commercial-grade stringer wire can be cut and fitted with end caps and plugs using slide-on vampire plugs. See the electrical accessories collection for vampire plugs and end caps.

What's the maximum run length for C7 stringer wire?

Maximum run length depends on the total wattage of the bulbs on the circuit and the gauge of the wire. Do not exceed the rated circuit load. Plan for power injection if your run is very long.
