Cree Inc of Durham, NC, USA has expanded its XLamp High Current LED Array family with new CMT LEDs that extend Cree’s latest metal-based chip-on-board (COB) LED technology to the most prevalent COB form factors.

In addition to providing up to 45% more lumen density and up to 17% higher efficacy, all Cree XLamp High Current LED Arrays feature a metal substrate technology that delivers higher reliability than competing metal COBs, it is claimed. With more than 6000 hours of LM-80 data available, the expanded family of LEDs enables lighting manufacturers to immediately upgrade their designs for DesignLights Consortium- and ENERGY STAR-eligible applications, such as track, downlight and outdoor lighting.

The CMT LEDs and the recently announced high-current CMA LEDs make Cree’s new metal-based COB technology available in form factors that are compatible with most commercially available holders and optics in the market. The newly expanded High-Current LED Array family (CMA and CMT) join Cree’s Standard-Density and High-Density families (CXA and CXA2), creating what is claimed to be the industry’s broadest portfolio of COB LEDs. COB LEDs mount directly to a heat sink without a separate circuit board, simplifying the luminaire manufacturing process and reducing system cost.

“Cree is a long-standing leader in developing reliability and lifetime standards for LEDs, such as IES LM-80 and TM-21, and we remain fully committed to upholding these methods,” says Dave Emerson, executive VP & general manager, Cree LEDs. “In light of recent reports of some companies falsifying lifetime data, our customers can remain confident that Cree LEDs, including our latest High-Current COB family, undergo rigorous testing to allow them to consistently deliver reliable long-term performance,” he adds.

The CMT LED family includes 10 LEDs across three (9.8mm, 14.5mm and 22mm) light-emitting surface (LES) sizes to address a wide variety of applications. Featuring Cree’s EasyWhite bins, the XLamp CMT LED arrays are available in 2700-6500K CCTs with standard color options of 70, 80 and 90 CRI (color rendering index) and premium color options that include high fidelity (98 CRI) and specialty color points.

Product samples are available now and production quantities are available with standard lead times.
