DOE Announces Winners of Reflector-CFL Competition: New lamps provide efficient downlighting and address issues about heat buildup
This article described results of phase II of a technology innovation competition for reflector compact fluorescent bulbs (R-CFLs) sponsored by DOE's Emerging Technologies program. DOE developed the competition to speed introduction of advanced, screw-based R-CFLs to the marketplace. The lamps are used in recessed can ceiling fixtures, the most popular fixture in American homes today. There have been concerns about heat buildup affecting the performance and longevity of R-CFLs in recessed fixtures located in insulated ceilings with airtight housings. To pass the competition, each lamp had to maintain acceptable light output levels and reach an average rated life of at least 6,000 hours in high-temperature testing. The winning R-CFLs also had to meet rigorous specifications for light output, beam angle, and maximum operating temperature. Eight lamps, manufactured by GE, Osram Sylvania, and Philips, passed the requirements, joining other models by Philips and Feit that were identified as winners during Phase I of the competition. All of the winning lamps are Energy Star certified. The winning models will be promoted on DOE's R-CFLwebsite http://www.pnl.gov/rlamps.
