DOE's LED Lighting Facts® program showcases LED products for general illumination from manufacturers who commit to testing products and reporting performance results according to industry standards. For lighting buyers, designers, and energy efficiency programs, the program provides information essential to evaluating SSL products.
Central to the program is the LED Lighting Facts label, which presents independently verified performance data in a simple summary that facilitates accurate comparison between products. The data is measured by the industry standard for testing photometric performance, IES LM-79, and covers five areas: light output (lumens), watts, efficacy (lumens per watt), correlated color temperature, and color rendering index. Optional information related to LED lumen maintenance and warranty may also be provided on the label.
Resources and Tools
Products registered with the LED Lighting Facts program are listed in an online, searchable database. Manufacturers have the option of submitting information in addition to the required label metrics, including color and light characteristics. The online product list summarizes the verified data in an easy-to-access way, equipping buyers to make informed decisions about the best products for their applications. The LED Lighting Facts program also offers periodic "Product Snapshot" reports that reveal how today's LED products really perform, drawing on analysis of the verified performance data from the product list.

DOE monitors the accuracy of reported product performance through random testing and periodic retesting. In November 2012, DOE hosted a Roundtable to explore needs and concerns related to the retesting. The Roundtable provided an opportunity for retailer, utility, specifier, and manufacturer partners to discuss how the LED Lighting Facts program can evolve and continue to be a valuable resource in the growth and development of the LED lighting market.
A working group under the joint auspices of DOE and the Next Generation Lighting Industry Alliance supports the efforts of LED Lighting Facts by developing and publishing guidelines and reports to help deepen our understanding of LED product performance and reliability. These efforts led to the development of the DOE LED Systems Reliability Consortium, a group of industry experts working collaboratively in an ongoing effort to develop an advanced luminaire reliability model for SSL manufacturers and end users.
