But the R-CFL problem is being addressed through a special publicprivate partnership between Pacific Northwest National Laboratory (PNNL) and lamp manufacturers. Two R-CFL lamps designed to perform in the hightemperature environment of recessed-can fixtures have entered the market and are available at advantageous prices. The lamps, manufactured by Philips Lighting Company, passed rigorous testing and specification requirements outlined by PNNL on behalf of DOE. They also meet or exceed Energy Star performance standards. The Philips EL/A BR30 16W reflector provides light output and warm-white color similar to a 65W incandescent reflector, and is a good replacement option for those interested in saving about two-thirds on their energy use.
