dc.description.abstractCompact fluorescent (CF) lamps, which are available as an energy-efficient replacement for ordinary incandescent light bulbs, can be used in a variety of fixture types, including existing incandescent, ceiling-mounted, recessed downlights. However, CF lamps are not shaped or sized identically to the incandescent bulbs being replaced; therefore, light distribution will be changed by these retrofits. Anny facilities have numerous incandescent downlight fixtures that are candidates for compact fluorescent retrofits. The information in this study can provide guidance for selecting appropriate retrofits. This study examined the photometric effects of installing several types of CF lamps in several types of incandescent downlight fixtures. Test results show that, for shallow depth fixtures, several types of CF lamps perform adequately. For deeper fixtures using nonreflective baffle rings, retrofitting with some CF lamps causes light output from the fixture to drop drastically. CF retrofits also caused a wider pattern of light distribution and increased luminance values. Changes in distribution and luminance need to be considered by Anny facility managers contemplating CF retrofits.en_US
