Cree® XLamp® CMT LEDs Deliver up to 45 Percent Higher Lumen Density than Competition

The new CMT LEDs extend Cree’s metal-based chip-on-board (COB) LED technology to the most prevalent COB form factors. Cree’s XLamp High Current LED Arrays provide up to 45% more lumen density and up to 17% higher efficacy, and feature an innovative metal substrate technology that delivers higher reliability than competing metal COBs. With more than 6,000 hours of LM-80 data, the expanded family of LEDs enables lighting manufacturers to upgrade designs for track, downlight and outdoor lighting.

“With the new High Current CMT LEDs, Cree has given us a full portfolio of solutions for our upcoming luminaire designs, in terms of both performance and ease of integration,” said Shawn Keeney, technology manager, Ledra Brands, a manufacturer of innovative, specification grade LED lighting fixtures and systems. “By choosing Cree, we know that we are leveraging the highest performance and best long-term reliability for COB LEDs to continue our leadership in solid state lighting design.”

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 industry-leading Standard Density and High-Density families (CXA and CXA2), which creates 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,” said Dave Emerson, executive vice president and 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.”

The CMT LED family includes 10 LEDs across three (9.8 mm, 14.5 mm and 22 mm) 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 2700K-6500K CCTs with standard color options of 70, 80 and 90 CRI 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. Please visit www.cree.com/cmt to learn more.
