DOE's CALiPER program has published a new Snapshot Report on LED MR16 lamps, which updates a similar Snapshot Report published in January 2014. In the past two years, LED technology has progressed rapidly, but the progress has been much slower for LED MR16s. The increase in mean efficacy is about half of that seen for other categories, and lumen output and center beam intensity (CBCP) haven't notably increased in recent years either. There are still no listed lamps at a given beam angle that meet the expected CBCP values for a 50W halogen MR16 using the ENERGY STAR® calculator – although several now meet the minimum threshold required by ENERGY STAR for claiming equivalency to a 50W halogen MR16.
