Cree has announced two new members of its CXA family of chip-on-board (COB) LED arrays including the CXA1304 with a 6-mm light emitting surface (LES) and the 12-mm CXA1816. Moreover, the entire CXA family is now available in a 95 CRI option. The company also added to its module family with a new version of the LMR2 that specifically targets residential solid-state lighting (SSL) downlights.

The new COB LEDs broaden the span of products that can be addressed with the CXA family. "The family of CXA LED arrays appeals to us because of the wide range of lumen options available, all at very high efficacy levels," said Michael Lin, CEO of Buckingham Industrial Group. "Regardless of the lighting application that we want to address, there is a CXA LED array offered that is optimized for it."

The CXA1304 LEDs deliver up to 1034 lm with typical efficacy of 102 lm/W at an 85°C operating temperature. The LED targets luminaires such as small track heads and downlights, or retrofit lamps such as small reflector bulbs.

The CXA1861 can enable replacements for 70W ceramic metal halide (CMH) spotlights as well as smaller luminaires and retrofit lamps. The LEDs can deliver up to 3000 lm.

The entire CXA family is LM-80 tested and offered across the range of 2700K–5000K CCTs. The new High CRI CXA versions feature both the 95 CRI and a typical R9 value of 85 at 3000K. Cree offers the LEDs in 2- and 4-step MacAdam Ellipse bins.
