Compact fluorescent lamps are used to replace incandescent lamps to aid in energy conservation in commercial and domestic lighting applications. In particular, they offer the benefits of much longer life and lower operating costs in a reasonably similar package. Some of the performance characteristics familiar to residential users may differ for the newer lamp technology. Such characteristics include response to ambient thermal conditions, sensitivity to lamp position, flicker, harmonics, etc. Of particular concern is the response to ambient thermal conditions, since lamps are used in unconditioned spaces, such as garages, basements, barns, and similar spaces where they may be subjected to extremes in temperature, both hot and cold. While it is well known that fluorescent lamp performance is determined by the cold spot on the lamp and can be affected by the ambient temperature in the room, the extent to which these findings, particularly for extreme in temperatures, apply to compact fluorescent lamp applications is not well understood.
