Rope lights are wired into sections; the length of which can vary depending on the type of rope light used. While this construction design makes it possible to custom cut the rope light into manageable sizes for a project, it can also make getting the correct length confusing as you have to factor in the predetermined section length...or what we call the "cutting interval."
For that reason, we've made this handy rope light calculator to help you determine the length of rope light you will be able to use. Start with your optimum, desired length of light, then enter in the appropriate "cutting interval" size. The calculator will then figure out how long your rope light will be able to be, based on the size of the rope light sections.
Refer to individual product specifications for allowable maximum run length.
