Context

Country: Canada
State/Province: Unknown
Period: circa 1910+
Canada: An example of an American made 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 light by means of an electric current which heats up a tungsten filament inside the lamp bulb to incandescence. This type of lamp was used for general lighting.
Technical: An example of a standard Westinghouse Mazda lamp, the usual vacuum type. Drawn tungsten wire simplified the manufacture of lamps and is easier to coil and concentrate the filament as required by focusing types of lamps. It also made the lamp very sturdy.
Area Notes: Unknown
