Category B is established as a future target for performance of SSL-based luminaires. Products cannot
qualify under Category B until three years after the effective date of these criteria. If technology improves faster than expected, and opening category B prior to completion of a three-year waiting period would be in the public interest, DOE will advance the date for allowing products to qualify under Category B.
DOE’s intent, is to substantially increase future performance requirements of LED Luminaires, and to
encourage continued improvement in technology selection and design of luminaires using SSL
sources. Products for a wide range of general illumination applications will be eligible.
The minimum luminaire efficacy target given for Category B is intended to rival today’s most
efficient lighting systems using traditional light sources.
T8 Fluorescent Lamp and Electronic Ballast Comparisons
For example, the best commonly available high-performance T8 fluorescent lamp and electronic ballast systems are rated around 100 lm/W. High-quality fixtures for these lamp-ballast systems are about 70% efficient,
yielding 70 lm/W luminaire efficacy.
Based on current commercially available technology, the Category B level of minimum
luminaire efficacy is not achievable for LED luminaires. However, DOE anticipates performance will rise rapidly over the coming years due to on-going progress in LED efficacy, LED high temperature tolerance, power supply efficiency improvements, and luminaire design.
DOE believes a significant number of general illumination products will be able to achieve 70 lm/W luminaire efficacy within three years after the effective date of these criteria.
DOE will monitor the technical progress of the technology, steadily adding additional Category A
products in future versions. If technology improves faster than expected, and opening category
B prior to completion of a three-year waiting period would be in the public interest, DOE will
advance the date for allowing products to qualify under Category B.

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.
ENERGY STAR rated LED decorative light strings! You'll save at the same time you brighting your neighborhood!
