Abstract: Summary—To increase the light output per watt, to improve the actinicity of the light, to increase the proportion of blue light badly needed for color photography, and to reduce the size and number and increase the output of the lighting units, tungsten lamp filaments are heated to temperatures as near the melting point as is practicable. Reference data are presented on lumen output, efficiency, color (energy) distribution, and lamp life. Practicable safe operating limits are indicated. A new “super photoflood” lamp is described and data on overvoltage lamp operation for location lighting are presented for reference.
