The Energy Conservation Potential Associated with Thermally Efficient Fluorescent Fixtures

This paper describes the energy conservation potential associated with thermally efficient fluorescent fixtures. Various approaches to improving fixture efficiency through the optimization of lamp wall temperature are discussed. The energy saving potential using thermally efficient fixtures is estimated for a sample lighting layout for an office space. This analysis indicates that both power density and the number of fixtures can be reduced with thermally efficient fixtures. Conservation potential on a national level is also estimated, using market profiles obtained from fixture manufacturers in conjunction with measured fixture performance data.
