Additional requirements can be found at the Energy Star website.Ī report that tracks the commercial availability and competitive positioning of MR16 LED and other retrofit lamps is available from Strategies Unlimited. In addition, the change of chromaticity from the lamp’s specified level over the lumen-maintenance period of 6000 hours must be within 0.007 on the CIE 1976 (u’v’) diagram. Energy Star certification requires ANSI-standard dimensions and base, >40 lm/W efficacy, minimum CRI of 80, R9 greater than 0, 70% maintenance of lumen output after 25,000 hours, and specific values for center-beam intensity based on 25W, 35W and 50W halogen equivalents.
The directional MR16 lamp performance is characterized by its center-beam intensity at its specified beam angle as well as lumen output. She added that meeting Energy Star requirements is critical as well so that utility rebates are accessible. “The main limitation has been with thermal management, where we needed to combine high lumen output in a very compact form factor,” said Ellen Sizemore, product marketing manager for Osram Sylvania. MR16 LED lamps are typically supplied with beam angles of 15, 25 or 36° and CCTs of 2700K, 3000K, 3500K or 4000K. In addition, a start-up company, Soraa, has designed an MR16 lamp based on GaN-on-GaN LEDs and it has told LEDs Magazine that its MR16 LED lamp will be commercially available in 3Q 2012 (see sidebar, p.
LED MR16 lamps are commercially available from companies including GE Lighting, LEDnovation, Lighting Science Group, Osram Sylvania, Philips Lighting and others, with some of the more recent offerings shown in Figs. This article discusses the low-voltage MR16 LED lamps, the most recent of which have been introduced as replacements for 50W halogen bulbs, and some of which have been certified by Energy Star. He is referring to the two forms in which MR16 lamps are offered: with GU-5.3 pins and powered by a transformed low-voltage AC input, or the second powered directly from the AC main voltage (120V in US, 240V in rest of world) through GU-10 pins. “The two greatest challenges in solid-state lighting retrofits today are MR16 and GU-10,” said Matt Reynolds, global IC applications manager at Texas Instruments. Moreover, due to its very small form factor, MR16s are subject to thermal management issues, so the LED junction temperature must be kept in an acceptable range to maintain lumen output and color quality, and it must be used in a fixture that allows heat to be dissipated. While all Energy Star qualified MR16 LED lamps are provided with a list of compatible dimmers and drivers, from a consumer standpoint, this level of complexity in purchasing a lamp can be limiting.

The user, whether a commercial lighting professional or homeowner, must understand the compatibility issues associated with plugging in an MR16 lamp and its interaction with existing transformers and dimmers. However, the use of MR16 LED lamps in existing sockets is less than straightforward. Soraa CTO responds to points made in LED MR16 design articleįor this reason, MR16 LED lamps, with their high efficacies and long lifetime offer a very attractive alternative to halogen MR16s, with their low efficacy of 15 lm/W and short lifetime of approximately 1000 hours.
