Context

Country: North America
State/Province: Unknown
Period: Unknown
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 Super-High output flourescent lamp produced 2 1/2 times as much light as previous standard rapid-start lamps. The development was made possible by the use of a mixture of rare gases that permitted extremely high-energy loading of the electrode arc stream, and the phosphor. The proper vapour poressure necessary to high operating efficiency, and which would normally be exceeded as the wattage of the lamp was increased, was obtained by the use of coolong chambers located at each lamp end. The lamps were developed primarily for medium and high bay industrial and outdoor lighting.
