The Fluorescent Lamp and its Application to Motion Picture Studio Lighting

Fluorescent lamps provide a new tool for solving some of the lighting problems encountered in the motion picture industry. A low-pressure glow discharge in mercury vapor and an efficient fluorescing powder are the chief features of such lamps. The differences between them and the ordinary filament lamps are many—not only with regard to design but with respect to their operating characteristics. These differences are discussed and many characteristics are shown for both the lamps and the necessary auxiliary equipment. The daylight quality of light which may be produced at high efficiencies and the relative lack of radiant heat make the new lamps attractive for several applications in studios.
