Compact Fluorescent Lamps
Berkeley Lab's success with the electronic ballast had showed the lighting industry that their work was significant and influential. Berkeley Lab reports describing the impact compact fluorescent lamps (CFLs) would have on national energy efficiency convinced the lighting industry to develop these energy efficient lamps. The Lab then provided lighting companies with consultations, prototype lamps and laboratory measurements, which helped advance the commercialization process.
Berkeley Lab researchers estimate that CFLs will have 10% market share in 2017, resulting in energy savings of 0.12 quads, 0.49 billion dollars in consumer benefits, and 1.9 MT of carbon emissions.
Another CFL application followed when Berkeley Lab researcher Michael Siminovitch saw reports of the fire hazard associated with halogen torchieres, a widely used floor lamp. He conducted photometric tests and discovered that these lamps burn at nearly 1,000 °F, an energy intensive and dangerously high temperature considering the proximity of people and furnishings. In contrast, compact fluorescent lamp (CFL) torchieres, which incorporate electronic ballasts, operate at about 100°F, posing no fire hazard. CFL torchieres produce about 45% more light than halogen torchieres and consume only one-quarter the energy.
CFL torchieres entered the market in 1997 and gained popularity because of concern over the fire hazards of halogen torchieres. Berkeley Lab worked with college housing authorities to develop halogen-for-CFL torchiere exchange programs for students, who accounted for a large share of halogen torchiere sales. These efforts expanded to utility energy conservation programs, military bases and other federal facilities, which began offering rebates or exchange programs to their customers and employees. Today many lighting manufacturers offer a variety of CFL torchiere models, sold in lighting, hardware and home improvement stores.
