Your gift to the environment

By choosing to use ENERGY STAR® certified LED holiday lights outdoors, you’ll help reduce electricity consumption at a time of the year when demand is especially high. Choose ENERGY STAR® certified bulbs—the most reliable and energy efficient on the market.

Bright benefits

Energy efficiency

Multicolor strings of ENERGY STAR® certified LEDs typically use 75% less energy than incandescents, and single‑color strings use 90% less.


They last 10 times longer than standard minibulbs.


Made from resistant material and containing no filament, the bulbs have a low risk of breakage.


ENERGY STAR® certified LED bulbs are a great choice since they come with at least a three-year warranty against defects (read the information on the packaging to ensure that the bulbs are CSA- or ULC-certified). Use sealed LED lights for outdoor use.

Did you know?

  • Indoor holiday lights shouldn’t be used outdoors, because the wires aren’t designed for winter’s temperature swings and harsh weather. The cold can cause breakage or overheating.
  • If you have strings of incandescent lights, don’t combine them with ENERGY STAR® certified LED sets. It’s best to use only LEDs, because they’re more efficient and draw less power.
  • Don’t cut LED cables or strips to shorten them. That would void the guarantee and could make them unsafe.
  • Don’t paint lightbulbs, because it takes a special kind of paint that is not always available in stores. Another type of paint could give off toxic fumes when the bulbs heat up.
  • Some pre-lit artificial Christmas trees can be put outside. But be sure they are designed for the purpose. There are a variety of trees with LED lights approved for outdoor use.
  • Lost or burnt-out bulbs in some strings can be replaced with compatible ones. You can buy replacement bulbs in stores that sell strings of lights. Look for more information on product packaging.
  • Strings of lights plugged together must never add up to more than 240 W per outlet. The wattage of LED holiday lights is so low that most households will practically never go over that limit. The total wattage of each string of LED lights is indicated on the package or on a little label attached to the wire.
