The FTC recently released more information on the new consumer facing label for medium screw based bulbs. DOE developed an overview that explains the FTC label and how it relates to the DOE LED Lighting Facts label.
In response to the multiple inquires concerning the FTC and DOE LED Lighting Facts labels, DOE developed quick answers for frequently asked questions.
As of April 2012, LED Lighting Facts partners have the option of listing an LED lumen maintenance projection on the label. This figure is written as a percentage of initial light output at 25,000 hours of operation at a given ambient test temperature, based on the combination of TM-21 projections and temperature measurements of the LED light source while operating inside the LED luminaire or replacement lamp. Partners can also indicate whether a warranty is available for a product. The LED Lumen Maintenance and Warranty Label Changes Frequently Asked Questions (541 KB, PDF) provides answers to common questions about these changes.
Using its up-to-date, independently verified performance data, LED Lighting Facts produces a Product Snapshot twice a year comparing the performance of LED replacement lamps to the new performance levels established by EISA and to the performance of existing technology. This snapshot profiles products in the LED Lighting Facts database, and will help anyone seeking opportunities in the LED replacement lamp market.
The U.S. Department of Energy (DOE) SSL GATEWAY Demonstration Program supports demonstrations of high-performance solid-state lighting (SSL) products in order to develop empirical data and experience with in-the-field applications of this advanced lighting technology. Each GATEWAY Demonstration compares SSL products against the incumbent technology used in a location. Below are summaries of the most recent demonstrations.
The Department of Energy's (DOE) Commercially Available LED Product Evaluation and Reporting (CALiPER) Program has been testing general illumination solid-state lighting (SSL) products since 2006. CALiPER summary reports provide analysis of photometric performance of SSL products, along with discussion of specific factors to consider for different lighting applications. Below are summaries of the most recent reports.

Read what DOE says about LED Lighting Facts in this two-page fact sheet, which provides a quick but thorough overview of the LED Lighting Facts program, the label, and how to participate.
The Residential Product Performance Scale is available to help you compare performance values of LEDs and standard residential lighting technologies for the five characteristics identified on the LEDLighting Facts label. The Residential Product Performance Scale can help you determine whether LEDs are appropriate for specific residential lighting applications.
A Commercial Product Performance Scale is now available to help you compare performance values of LEDs and standard commercial lighting technologies for the five characteristics identified on the LED Lighting Facts label. The Commercial Product Performance Scale can help you determine whether LEDs are appropriate for specific commercial lighting applications such as office spaces and outdoor area lighting.
The U.S. Department of Energy (DOE) has made a long-term commitment to provide national leadership to advance research, development, and market introduction of solid-state lighting. DOE’s support of solid-state lighting is essential to ensure the development of energy-efficient, high-performing LED technology—a focus that might otherwise be lost on the path to commercialization.
