Can a SpringLight compact fluorescent bulb be used in a dusk-to-dawn fixture?
Dusk-to-dawn photocell fixtures designed for screw-in incandescent bulbs contain a silicon chip that converts radiant energy into electrical current. The technology is generally incompatible with screw-in CFLs, shortening the life of the bulb. However, fixtures with built-in photocells that are designed to use only compact fluorescent lamps contain a delayed instant-on circuit to make them compatible with fluorescents.
