• A decorative light string that has earned the ENERGY STAR uses 50 percent less energy than an incandescent light string.

    Note: Savings are based on comparing the weighted average energy use of regular- and mini-incandescent light strings to the weighted average energy savings of regular- and mini-decorative light strings.

  • If all decorative light strings sold in the United States were ENERGY STAR certified, the energy cost savings would grow to about $195 million each year and 2.4 billion pounds of annual greenhouse gas emission would be prevented, equivalent to the emissions from nearly 235,000 vehicles.
