- are more durable and shock-resistant than incandescent strings
- have a minimum three year warranty
- use LEDs that last up to 10 times longer than incandescent bulbs
Coloured light strings must have an average maintained light output of no less than 70 percent to qualify for ENERGY STAR. Strings containing white or phosphor-based lamps must have an average maintained light output of no less than 50 percent to qualify.
