2001. Fluorescent Lamp Retrofits: Savings or Fantasy?. 0171 2310. Missoula, MT: U.S. Department of Agriculture, Forest Service, Missoula Technology and Development Center. 6 p.
Evaluates the savings from retrofitting standard 4-foot F40T12 fluorescent lamps and magnetic ballasts in Forest Service buildings. Modern fluorescent lamps may pay for themselves through energy savings in a couple of years or less, depending on the cost of electricity. The modern lamps also provide a higher quality light. New T8 fluorescent lamps with a high color rendition and electronic ballasts should be used in all new buildings and retrofits. Information on the nomenclature used for fluorescent lights and tips for maintenance, performance, and safety are included. A glossary of lighting terminology and detailed information on calculating energy savings, heating and cooling savings, and simple payback for the lighting system retrofit at the Missoula Technology and Development Center are available in the summary.
