Tungsram

Tungsram was a manufacturing company located in Hungary and known for their light bulbs and electronics. Established in Újpest (today part of Budapest, Hungary) in 1896, it initially produced telephones, wires and switchboards. The name "Tungsram" is a portmanteau of tungsten (/ˈtʌŋstən/ TUNG-stən) and wolfram (/ˈwʊlfrəm/ WUUL-frəm), the two common names of the metal used for making light bulb filaments. Before becoming nationalized by the Communist government in 1945, the company was the world's third largest manufacturer of light bulbs and radiotubes, after the American General Electric and RCA companies.

In February 2018, the CEO of GE Hungary, Jörg Bauer, agreed to buy GEʼs lighting business in Europe, the Middle East, Africa and Turkey, as well as its global automotive lighting business. The business continued to operate again under the name Tungsram Group.
