Context

Country: North America
State/Province: Unknown
Period: mid 1940s +
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: Germicidal lamps radiate more than 85% of their energy at a wavelength of 254nm in the ultraviolet spectrum, a radiation which kills bacteria and other micro-organisms and is used for sterilization.
Area Notes: Unknown
