Cree Debuts Discrete High-Density XB-H LEDs

Cree, Inc. introduces the XLamp® XB-H LED, the brightest discrete in Cree’s high-density (HD) class of LEDs, delivering a breakthrough combination of lumen output and efficacy in a small package.

The XB-H LED brings the lighting-class performance of the XP-G2 LED into a package that is 50 percent smaller. Delivering more than 500 lumens at 1.5A, 25º C in a 2.45 mm2 package, the Cree® XB-H LED can enable luminaires that use the same size footprint XB-D LED to triple their light output at the same efficacy.

The XB-H joins the XQ-E in the family of HD class discrete LEDs that offer the industry’s highest optical control factor (OCF), a measurement of how LED size and performance benefit directional lighting applications. High OCF LEDs enable lighting manufacturers to improve the performance of any lighting design, create smaller and less expensive systems, and develop new lighting solutions that were previously not possible.

“Cree is the first LED manufacturer to bring this level of performance to such a small size,” said Roger Suen, Supply Chain Management Director, Light Engine Ltd. “With a high optical control factor, the XB-H LEDs enable new levels of brightness and optical control to improve design flexibility, increase performance and lower system cost without sacrificing reliability.”

Utilizing Cree’s proven and highly reliable ceramic package technology, the new XB-H LED delivers long L70 lifetimes at both high temperature and current. In addition, the XB-H offers compatibility with most optics designed for the Cree XP family of LEDs, allowing lighting manufacturers to leverage the optics of existing lighting designs and improve time to market.

“We are excited to offer our breakthrough high-density performance to manufacturers who prefer to work with discrete LEDs,” said Dave Emerson, vice president and general manager for Cree LEDs. “Delivering up to 175 lumens-per-watt efficacy at 1W, 25°C in its small package, the XB-H LED sets a new performance standard for high power LEDs. Our new HD class of discrete LEDs demonstrates Cree’s commitment to offering customers the best options for their applications.”

To improve time to market, lighting manufacturers seeking ENERGY STAR® qualification can take advantage of the XB-H LED’s successor status to the XP-G2 LED—meaning that ENERGY STAR qualification can be achieved using just 3,000 hours of LM-80 data, instead of the normal 6,000 hours.

The XLamp XB-H LED is available in color temperatures ranging from 2700K to 8300K and CRI options of 70, 80, 85 and 90. Binned at 700mA, 85°C, the XB-H LED delivers up to 499 lumens at 5W, 85°C. Product samples are available now and production quantities are available with standard lead times. Please visit www.cree.com/ocf to learn more.
