DOE Publishes CALiPER Snapshot Report on LED A Lamps

The U.S. Department of Energy's CALiPER program has released a Snapshot Report on LED A lamps, which utilizes the LED Lighting Facts® program's extensive product database to help industry stakeholders understand the current state and trajectory of the market for that class of products.

Among the key findings:

•    The mean efficacy of all A lamps listed by LED Lighting Facts has steadily increased, and is now at 69 lm/W.
•    95 percent of those lamps meet the current ENERGY STAR® efficacy criterion, and nearly 90 percent meet the ENERGY STAR criterion set to take effect in September 2014.
•    While the overall numbers for efficacy are favorable, there’s still wide variation for individual products; e.g., those with lumen output equivalent to a 60W incandescent lamp range from less than 60 lm/W to nearly 90 lm/W.
•    Several LED A lamps are now available with lumen output equivalent to traditional 75W and 100W incandescent A lamps.
•    Approximately 91 percent of currently listed LED A lamps have a color rendering index (CRI) in the 80s, and most of those prod¬ucts have a nominal correlated color temperature (CCT) of either 2700 K or 3000 K. It remains to be determined if this performance level will be acceptable to consum¬ers, or if there will be significant demand for higher-CRI products.
