Philips Lighting informed 84 employees at its Danville plant on Thursday that the factory will close in February, a company spokeswoman said.
The plant makes glass for incandescent bulbs. It employed as many as 300 people in the early 1980s.
The closing date for the plant is Feb. 18, spokeswoman Silvie Casanova said.
"The global lighting industry has been changing, and Philips has decided that in order to improve operational efficiencies, it's going to phase out the manufacturing" at its Danville plant, Casanova said.
Never miss a local story.
"The whole industry is moving towards more energy-efficient technology, and this plant makes glass for incandescent bulbs, which are considered to be the most inefficient technology for lighting," she said.
The plant opened in Danville in 1952 as Corning Glass Works. Corning sold the plant to Philips in 1983.
