The XLamp CXA20 LED array from Cree can illuminate a 60W A-lamp using just 11W.
With a single, uniform optical source, 22x22mm footprint, and simple two-screw attachment, the array claims to make the development process easier with a single component in the light engine design. The array delivers 1050 lumens at 11W, or 2000 lumens at 27W, with a 3000K warm white colour temperature.
