Helpful Information
The 25-foot cords come with male and female plug ends and can be connected with other 25-foot cords up to two (2) in series. The 50 and 100-foot cords come with a single male plug. We suggest you connect them from a centrally installed splitter in a T formation.
The 1000-foot spools do not come with plugs. Gilbert plugs are our favorite choice to use with 18 AWG wire.
SPT-1 and SPT-2
SPT-1 and SPT-2 are specifications describing the thickness of the insulation of traditional 18 AWG C7 cords. SPT-1 is the type most commonly used by commercial Christmas light installers. SPT-2 is thicker and tailored to harsh weather conditions. Gilbert plugs must match. Read more: What is the difference between ST-1 and SPT-2?
Common Sense Alert
Important Note regarding 1000-foot spools: You cannot hook up all 1000 feet in a continuous run of lights but must cut it into at least four sections of 250 feet or less - less for higher wattage incandescent bulbs. Do not exceed 250 feet of 18 AWG wire in a single circuit, no matter the kind of bulb you are using, and do not exceed 1000 Watts per typical household breaker. Please consult with a Master Electrician as you design and install your project.

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!)
