Abstract: The luminous and electrical characteristics of a number of vapor discharge lamps that have attained practical importance in recent years are described. These include the sodium vapor lamp, the high-intensity mercury vapor lamp, and the high-pressure quartz capillary lamp. The fundamental physical phenomena and the manner in which these affect the light output and efficiency are discussed briefly. The effect of variations in gas pressure and current density upon the distribution of intensity in the spectrum is dealt with, and also the accompanying changes in intrinsic brilliancy and color of light emitted. The latter part of the paper contains a discussion of recent developments in the utilization of fluorescent materials in gaseous discharge lamps. These lamps offer interesting possibilities from the point of view of general illumination and special color effects.
