Mercury Lighting for Television Studios

This paper includes a brief history of the use of water-cooled Mazda H lamps, a light that is cooler than noon sunlight, for television studio lighting, with a detailed description of an installation of remote-controlled floodlights in the General Electric Television Broadcasting Studio WRGB at Schenectady, New York. Results are shown by photographs of the line-monitor tube picture when the illumination of the set is provided by mercury lamps. Lamp performance is discussed and data on light maintenance presented.
