If all decorative light strings sold in America this year were ENERGY STAR qualified, we would save over 2 billion kWh per year and reduce greenhouse gas emissions equivalent to nearly 300,000 cars!
ENERGY STAR qualified decorative light strings — many which feature LED technology — consume 75% less energy than conventional incandescent lights strands.

ENERGY STAR Qualified Decorative Light Strings:
- 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.
