Cree launches XLamp MT-G LED for 35–50W halogen MR16 retrofits

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has made available samples of a new lighting-class LED designed for high-output, small-form-factor directional lighting applications.

The XLamp MT-G LEDs are optimized for 35–50W halogen MR16 retrofit bulbs and other accent, track, display and down-lighting used in retail stores, residential settings, museums, art galleries, hospitality and landscapes. They are the first commercial LEDs to deliver sufficient light output for these applications, claims Cree.

The multi-die XLamp MT-G LED features Cree EasyWhite technology to deliver consistent color in a small (9mm x 9mm) highly efficient package. The LED is designed for the high-lumen, small-footprint requirements of 35 and 50 Watt halogen retrofit lamps. Cree says that it engaged driver, thermal and optic providers to create an MR16 lamp reference design to further enable its LED customers to quickly address this market.

Cree claims that the MT-G is the first LED in the industry binned and tested at 85ºC, which can simplify luminaire design calculations and speed time-to-market. At 85ºC, the MT-G LED delivers up to 560 lumens at 1.1A or up to 1525 lumens at 4A in warm white (3000K).

“There are no energy-efficient alternatives for many high-lumen, small-form-factor, directional lighting applications,” says Paul Thieken, director of marketing, LED components. “Until now, LED-based MR16 lamps have been a tremendous challenge for the lighting design community in terms of both light output and color consistency due to their small size and limited capacity for thermal management,” he adds. “Cree developed this LED from the ground-up with applications like these in mind, and its introduction signals the arrival of the LED lighting revolution in these high-profile markets.”

Production volumes are available with standard lead times. The reference design is available for free at http://mtg.cree.com.
