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.
The key findings include:
* The mean efficacy of all A lamps listed by LED Lighting Facts has steadily increased, and is now at 69 lumens/W.
* 95% of those lamps meet the current ENERGY STAR efficacy criteria, and nearly 90% meet the ENERGY STAR criteria set to take effect in September 2014.
* While the overall numbers for efficacy are favorable, there is still wide variation for individual products; e.g., those with lumen output equivalent to a 60W incandescent lamp range from less than 60 lumens/W to nearly 90 lumens/W.
* Several LED A lamps are now available with lumen output equivalent to traditional 75W and 100W incandescent A lamps.
* Approximately 91% of currently listed LED A lamps have a CRI in the 80s, and most of those products have a nominal correlated color temperature of either 2700K or 3000K.
