Compact fluorescent lamps work on the same principle as Tubular Fluorescent Lamps. Theyare particularly suitable for incorporation in small luminaire housings. The use of compact fluorescent lamps greatly extends the range of applications for fluorescent lamps. Compact fluorescent lamps require a ballast for starting and current limitation when operating (2-pin base) and also a starter (4-pin base). The latest developments in the field of ultra-compact energy-saving lamps with screw caps (E14, E27) permit them to be used in place of conventional incandescent lamps, but this type is not dimmable.
