Abstract :
A slender green tube 18 inches in length, introduced to illuminating engineers in 1935, is the progenitor of today´s vast fluorescent lamp industry. Since that time, the basic methods of operating the tube have changed little. Engineers have improved and elaborated on fundamental system elements, such as ballasts, starters, and cathodes; as a result of their work, a large variety of lamps is available to the public.
