Lighting Industry's Future Dims As Efficient LED Bulbs Take Over

A revolution is upsetting the lighting business as LED lightbulbs replace energy-hogging incandescent ones. This is good news for consumers and the environment; using less energy reduces the greenhouse gases that contribute to climate change. But this shift comes with a cost, exemplified by a century-old lightbulb factory in St. Marys, Pa., that is the latest to shut down. For much of its long history the LEDVANCE facility, 120 miles northeast of Pittsburgh, produced lightbulbs under the Sylvania brand. Now all it produces is scrap metal.
