Electric Lamps

July 1941

A worker at the Westinghouse Lamp Division, Bloomfield, N.J., measures powders in preparing the fluorescent phosphors which coat the insides of Mazda fluorescent lamps.

Although the powders are white in color, they glow brilliantly in many shades under ultraviolet light. Different kinds of powders are mixed in the proper proportions to give different colors of light.
