Abstract

This issue of Specifier Reports contains performance data for compact fluorescent lamps (CFLs) rated at or above 13 watts. The report includes NLPIP test data and manufacturers' data on both self-ballasted CFLs and modular CFL products that are sold with ballast and lamp packaged as a single unit. Introduced in the U.S. in 1979, CFLs replace incandescent lamps in a variety of luminaires with medium screwbase sockets. CFL products can reduce energy and maintenance costs compared to incandescent lamps. These lamps have a tube diameter of 5/8 inch (16 millimeters) or less and are available in various shapes. Some circular fluorescent lamps have larger diameters, but this report treats them as CFLs because they are compact in overall size and can be used as alternatives to incandescent lamps.
