The advancement enables radically new and differentiated LED lighting form factors for applications like track lights, lamps and downlights. For example, the CXB1520 LED packs the lumen output of seven 60-watt replacement lamps into an area much smaller than a dime, allowing lighting manufacturers to put more light where it is intended at a lower system cost.

“The CXB1310 High Density LED array delivers an impressive amount of light in a small package,” said Massimo Parravicini, R&D director of Reggiani Illuminazione. “The high lumen density of the CXB1310 LED will allow us to offer LED designs with performance and form factors previously impossible.”

The high performance of the CXA2 High Density LED arrays allow lighting manufacturers to reduce thermal, mechanical and optical costs at the system level. For example, when combined with a 74mm diameter optic, the 3000K, 80 CRI CXB1520 High Density LED array delivers over 50,000 candela in a 10-degree beam while drawing only 40 watts.

This high lumen density allows lighting manufacturers to deliver the performance of a 70W ceramic metal halide (CMH) PAR38 lamp through a much smaller PAR20-size optic using 43 percent less power. The CXB1310 High Density LED array delivers up to 3,200 lumens in a 6mm LES, allowing similar reductions in size and power from traditional light sources.

“The CXB1520 High Density LED allows us to deliver downlights that provide up to 2700 lumens with just 28 watts in a very small 4” trim platform. What was previously only possible in much larger platforms with much higher wattage requirements is now made possible in our VF Series Specification Grade Luminaire Downlight product line using Cree’s CXB1520 High Density LEDs,” said Justin Weaver, Vice President Engineering, LF Illumination.

“The very high efficacy of the CXB1520 High Density LED also allows us to move many of our products that at one time were only possible with active cooling solutions to passive solutions, simplifying our design and lowering our system costs significantly.”

Offering the industry’s best color consistency for designs that use only one LED, Cree XLamp CXA2 High Density LED arrays are characterized and binned at 85°C, available in 2-, 3- and 5-step EasyWhite color temperatures (2700K – 6500K), and CRI options of 70, 80 and 90. The CXB1310 and CXB1520 LEDs have LM-80 long-term test data available immediately, delivering reported L90 lifetime projections of at least 36,300 hours at 85°C and 105°C.
