E12 (C7) Christmas Light Cords and Spools

We have one of the largest selections of C7 cords and spools on the internet. If you need non-standard spacing, you're in the right place!

People choose our C7 stringer wire because:

  • They need a commercial quality solution for their home or business
  • They want to customize their sets with their choice of wire and bulb colors in either LED or incandescent
  • They want to choose between different socket spacings 

Decorating with different lengths of C7 Christmas light cords


These C7 stringers are perfect for lighting either short or long distances and replacing old worn wiring. Each cord features 25 sockets spaced 1 foot apart.

We love to use these C7 cord sets in our front flower beds. We've doubled them up for an effective bulb spacing of 6 inches and they look great. The bulbs are the same size as night light bulbs and make a great accent for the front of our home. We switch these out through the year - our neighbors are always wondering what we'll be doing next!

(Speaking of night lights - these do have the same bases as night light replacement bulbs and let you get really creative with your night light colors. Our son loves his dark transparent blue bulb!)

Understanding 25-ft Light Cords and Their Limitations: These standard cords are ideal for lighting short distances or replacing older, similar type cords. Each cord features 25 sockets spaced 12" apart on 20-gauge wire. 

But remember: Plugs on these 25-foot C7 cords feature a 5-amp fuse - allowing only two cords to be connected end-to-end or you'll blow the fuse in the plug.


These Commercial 100-Foot C7 Cords feature C7 sockets spaced 12 inches apart and feature a 20 foot lead wire for easier installation eliminating the need to use an extension cord in many applications.
These cords are constructed with heavy duty 18 gauge wire and the sockets are rated for outdoor use.

An easy installation soluton, you'll like the fact that these C7 cords are fuseless, and polarized.
