Decorative Light StringsEarning the ENERGY STAR means products meet strict energy efficiency guidelines set by the US Environmental Protection Agency. Lighting products that have earned the ENERGY STAR deliver exceptional features, while using less energy. Saving energy helps you save money on utility bills and protect the environment by reducing greenhouse gas emissions in the fight against climate change.

ENERGY STAR Certified Decorative Light Strings:

  • use 50% less energy than conventional incandescent lights strands.
  • can last up to 10 times longer than traditional incandescent strands.
  • are cool to the touch, reducing the risk of fire.
  • do not have moving parts, filaments or glass, so they are much more durable and shock-resistant than other light strings.
  • are available in a variety of colors, shapes and lengths.
  • come with a three-year warranty, meaning fewer light string replacements.
  • are independently tested to meet strict lifetime and electrical requirements.
  • products labeled for outdoor use are subjected to weathering tests.
  • some models deliver features such as dimming or color shifting.

Many ENERGY STAR certified decorative light strings feature LED technology. What is an LED?

  • Light emitting diodes, or LEDs, are small light sources that are illuminated by the movement of electrons through a semiconductor material.
  • LEDs are exceptionally energy efficient when producing individual colors, many using up to 90% less energy than an incandescent bulb to produce the same amount of light.
  • For example, the amount of electricity consumed by just one 7-watt incandescent bulb could power 140 LEDs — enough to light two 24-foot (7.3-meter) strings.


Current Specification Effective Date: March 2008

Decorative light strings originally qualified for the ENERGY STAR label in August, 2007. ENERGY STAR qualified decorative light strings consume 50% less energy than conventional incandescent lights strands.

  • Products must meet stringent efficiency (no more than 0.2W per bulb) and quality (3-year warranty, protection against over-voltage, maintained light output) requirements.
  • In addition, qualified light strings must meet product packaging requirements to ensure consumers have a clear understanding of products when they look to purchase light strings.

Did You Know?

If all decorative light strings sold in the United States this year were ENERGY STAR certified, the energy cost savings would grow to about $45 million each year and we would prevent over 630  million pounds of greenhouse gas emissions annually - equal to those from about 60,000 cars!
