Cree, Inc. (Durham, NC) offers the XLamp® CXA20 LED array, which can enable a 60-watt A-lamp equivalent while consuming 11 watts. With a single, uniform optical source, compact 22mm x 22mm footprint, and two-screw attachment, the CXA20 array simplifies the manufacturing process for customers who require a single component in their light engine design. When used in a traditional downlight application, luminaires based on the CXA20 deliver 38-percent more illumination than a 26-watt CFL or a 100-watt incandescent bulb, while consuming 14 watts. The array delivers 1050 lumens at 11 watts — or 2000 lumens at 27 watts — with a 3000-K warm-white color temperature.
