Tungsram is an Hungarian manufacturer of light bulbs since 1896. General Electric, in 1990, acquired majority share in one of Hungary’s largest, oldest, and internationally most prestigious firms, the light-source manufacturer Tungsram.

Over the past six years GE has invested $600 million in the venture and thoroughly restructured every aspect of its operations.

It is the largest U.S. manufacturing investment in Central and Eastern Europe up to date. It is now a subsidiary of General Electric and its name is used as a brand name only.
