Cooper-Hewitt "Uviarc" lamp

Description (Brief):

Cooper-Hewitt "Uviarc" mercury vapor lamp, ca. 1919. No base - double-ended quartz discharge tube with metal sleeve at one end, ceramic insulated wire lead at other end. Tungsten anode, mercury pool cathode. Tipped quartz envelope with bulbous end. Unit appears to be of the 220 volt rating. Lamp starts by tipping unit such that the mercury runs from one end to the other, making contact with both electrodes initiating an arc. The electrical arc is tightly confined along the axis of the lamp. This is a mercury vapor lamp designed to produce ultraviolet radiation for germicidal purposes. "8854" and "Uviarc" stamped on base.
