This issue of Specifier Reports presents photometric, electrical, and thermal performance data for selected CFL residential downlights that qualify for ENERGY STAR® approval. Since 1980, the trend in residential new construction and remodeling has been to install recessed downlights as the predominant luminaire. Their clean, low-profile appearance appeals to many consumers. This report examines recessed downlight components, installation, operation, and performance. Related reports: See Specifier Reports: CFL Downlights (NLPIP 1995) for information on spacing criterion and glare related to residential downlights. See Specifier Reports: Energy-Efficient Ceiling-Mounted Residential Luminaires (NLPIP 1999b) for general information about performance issues.
