The halogen MR16 has been a workhorse lamp for display and accent lighting applications, with millions of these lamps installed today. Halogen MR16s, particularly with the popular 50W lamps, provide retail and display lighting applications with a 12 volt, point source, small 2" diameter aperture lamp, excellent color temperature and color rendering characteristics, beam angle options as well as light control accessories such as special lenses. It is now another year later, a good time to revisit the status of LED MR16 lamps. That report showed that LED MR16 lamps intended to replace 20W and 35W halogen MR16s performed reasonably well, but LED replacements for the popular 50W category of halogen under-performed compared to halogen. In November 2015, USDOE published a follow-up report (see below) on the status of LED MR16s. In addition the number of LED MR16 products on the market was declining significantly, an indication of the difficulties manufacturers faced with this category of LED lamp. Most manufacturers did not even bother to provide that specification. Only one lamp tested provided comparable center beam candlepower. Over two years ago, when we wrote this original post, there was general angst from lighting designers, contractors and owners about the usefulness of LED MR16 bulbs as viable replacements for halogen MR16 in commercial display lighting applications.Īt the time, we cited a USDOE report from 2014 that showed "very few of the LED MR16 lamps listed in the LED Lighting Facts program are comparable replacements for the popular 12V 50W halogen MR16".
