LED MR 16 Lamps: New DOE ‘CALiPER’ Snapshot Report

Here’s a two-page (PDF) DOE SSL “Postings” report on the LED MR 16 findings:

[a 2013 DOE report showed that] LED MR16s had the highest penetration rate of all LED lamps in 2012, at about 10 percent of all MR16 lamps.

But conventional halogen MR16s are very tough competition. Used extensively in retail and display lighting, they deliver focused illumination from their 2″ aperture, have desirable color quality, are easy to use with controls, and are available with a range of different options (e.g., beam angle) and accessories (e.g., spread lenses).

- – -

This makes them one of the most difficult lamp types for LED technology to successfully replicate –especially 12V/50W halogen lamps, the highest wattage that’s commonly available.

- – -

The new Snapshot shows that despite noted performance improvements and many claims to the contrary, few LED MR16 lamps listed by LED Lighting Facts are one-for-=one replacements for a 12V/50W halogen MR16 lamp.

Such equivalency claims may be applicable if comparing a GU5.3 base LED lamp to a GU10 base (120V) halogen lamp, but those comparisons are misleading.
