High-Intensity Mercury and Sodium Arc Lamps
Characteristics of the sodium and high-intensity mercury arcs of interest to motion picture engineers are discussed, including starting, stability, regulation, power-factor, and multiple and series operation. Energy distribution as related to the sensitivity curves of photographic emulsions and to the use of filters is shown by graphs. Methods of controlling the light distribution and intensity are explained.
