What Kind of Extension Cord Do I Need for Outdoor Christmas Lights?

When it comes to decorating for the holidays, the best way to make your home stand out is with outdoor Christmas lights. However, before you can start stringing up your lights, you need to make sure you have the right type of extension cord. The type of extension cord you need depends on how much power your lights are going to need, and what kind of environment they will be in.

The Power Requirements

The first thing you’ll need to consider is how much power the lights will require. If they are low voltage LED lights, then you’ll need a 12-gauge cord.

If they require more power, such as a larger set of incandescent lights or a pre-lit tree, then you’ll need a 10-gauge cord. The larger the gauge number, the more powerful the cord.

The Environment

The next thing to consider is what type of environment your lights will be in. If they are going to be exposed to water or snow, then you’ll need to use an outdoor rated extension cord. These cords are designed to withstand harsh weather conditions and keep moisture out so that your lights stay safe and dry.

Types of Extension Cords


Once you know the power requirements and environment for your Christmas lights, it’s time to pick the right type of extension cord. There are several types available that can handle different power levels and environments:

  • Indoor Extension Cords: These cords are typically 12-gauge and made for low voltage LED or string lights.
  • Outdoor Extension Cords: These cords are typically 10-gauge and made for higher voltage incandescent or pre-lit trees.
  • All-Weather Extension Cords: These cords are designed for outdoor use and feature special insulation that protects them from moisture.

.

. When choosing an extension cord for outdoor Christmas lights, it’s important to consider both the power requirements and environment in which they will be used.

Indoor extension cords are suitable for low voltage LED or string lights while outdoor extension cords should be used with higher voltage incandescent or pre-lit trees. All-weather extension cords offer extra protection if your decorations will be exposed to moisture or snow.
