Period

circa 1940+

Canada

An example of a lamp bulb used in Canada, part of a large and varied collection of over 7500 electrical items acquired and documented by Ontario Hydro in the 1960s. The collection was thought to be the largest and most comprehensive of its kind in Canada and was donated to the Canada Science and Technology Museum in 1992

Function

A device used to provide illumination by means of an electric current which excites mercury vapour in a glass tube, producing short-wave ultraviolet light that then creates fluorescence, producing visible light. This lamp bulb emits black light.

Technical

Black light was developed for theatrical or decorative applications. For example, black light was used at the Museum of Science and Industry in New York to illustrate a model of an atom and to create the illusion of the atom floating in space. Black light was also used for military purposes for inspection of the protective coating on machine parts that was only visible under black light, as well as cracks in castings and metal.
