Cree Introduces the Next Generation of Lighting-Class LEDs

Driving the next generation of mainstream LED lighting adoption, Cree, Inc. has introduced the breakthrough XLamp XB-D LED. The first LED based on an innovative new Cree technology platform, the XLamp XB-D LED ushers in a new era of price-performance for lighting-class LEDs. This LED can further simplify designs, ultimately removing a key barrier to widespread LED implementation—up-front system cost.

The XB-D LED delivers twice the lumens-per-dollar of other LEDs, in the industry’s smallest lighting-class footprint of 2.45 mm by 2.45 mm. The XB-D LED is 48 percent smaller than the XLamp XP package and well suited for lighting applications where high lumen density and compact light sources are required. The innovations behind this next generation of lighting-class LEDs can enable significantly lower prices for LED lighting products by using up to three times fewer LEDs, three times fewer optics and substantially smaller circuit boards than current designs.



“Being a leader means delivering revolutionary, not evolutionary, innovation to drive the LED lighting revolution,” said Mike Watson, Cree senior director of marketing, LED components. “With this new platform Cree has fundamentally redefined the price-performance paradigm for our components customers. It’s not enough to just make LEDs brighter—it’s also about improving product payback and market acceptance of LED lighting.”

Leveraging Cree’s proven silicon carbide technology and expertise, the XB-D LED delivers up to 139 lumens and 136 lumens per watt in cool white (6,000 K) or up to 107 lumens and 105 lumens per watt in warm white (3,000 K), both at 350 mA and 85°C.



XB-D LEDs are also compatible with most existing XP family secondary optics, which can speed the optical design process and create direct cost savings for existing XP family-based designs.

100 Watt Constant Current AC/DC LED Power Supply 
Green Watt Power, a Division of Calex Mfg., has released the GLC-100 series of constant current AC/DC LED power supplies. The GLC-100 series with universal / full range AC input voltage of 100 to 277 VAC, offers stable and reliable 100 W output power and is available in six different models of constant current output at 1.75 A, 2.1 A, 2.45 A, 2.8 A, 3.2 A or 4.2 A with self-adjusting output voltage from 15 VDC to 54 VDC range in the various models. All models are enclosed to IP67 standards in extruded aluminium metal case design and well-suited for virtually all LED lighting applications for indoor, outdoor, signage, refrigeration, thermally harsh and damp environments.

The GLC-100 has efficiencies in the 90 percent range in the series with active power factor correction greater than 0.90 on every model. All units in the series have over voltage, over current, over temperature protection and are RoHS Compliant. Safety Agency approval is pending to UL/CSA 8750 and 1310 class 2 or 1 depending upon the model. Products in the series are CE approved. The product case dimension is 6.61” (L) by 3.15” (W) by 1.65” (H) with customer mounting provisions designed in the case design. All products in the series are designed and built for consistent performance and high reliability and come with a 5 year warranty.
