C9 - SPT1
SPT1 C9 socket wire is a parallel wire with a specific insulation thickness (SPT1) that is designed to be used with C9 Christmas light bulbs and sockets and to create custom-length Christmas light strings. It allows for the attachment of C9 sockets at specific intervals to accommodate C9 bulbs. Spacing options span from 6" to 36" depending on wire color and roll length.

C9 - SPT2
SPT2 C9 socket wire is often referred to as commercial grade because it's designed for professional use, offering durability and reliability for long-term installations. This type of wire is frequently used for creating custom Christmas light displays on rooftops, pathways, and other outdoor areas, as well as for general-purpose low-voltage lighting. The "C9" designation indicates compatibility with C9-sized Christmas light bulbs, which have an E17 base.
