Context

Country: North America
State/Province: Unknown
Period: late 1950s+
Canada: An example of a lamp bulb made and 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 Rapid start bulb started quickly and smoothly within one second after being turned on. The new design eliminated blinking and flickering of the light. Rapid Start bulbs were covered with a coating called Dri-Film that improved their illumination in humid conditions.
Area Notes: Unknown
