Thorn also had a very long-standing arrangement with Tungsram (Hungary), whose valves freuently appear branded Brimar. That lasted way beyond the days of valves, through to the acquisition of both Thorn and Tungsram by GE USA, to the purchase of the whole of the European/Middle Eastern lighting business of GE, by Tungsram, as a MBO by the Hungarians.
