Period
mid 1940's+
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.
Technical
The Mazda lamp is an important example of social construction of technology. The introduction of high-efficiency Mazda lamps, trademark of Westinghouse/GE, was strongly opposed by electrical utilities afraid to lose the revenues from sales of electricity. The Mazda companies were forced to redesign the lamp.
