General Electric ( GE) plans to close several plants in its lighting business as it shifts focus away from incandescent bulbs to more energy-efficient products.The move will result in about 1,400 job cuts, the conglomerate said Thursday. GE is in the midst of restructuring its lighting business -- something that's been symbolically tied to the company since its founding by lightbulb inventor Thomas Edison -- as more customers embrace high-tech products that save electricity. The company aims to focus on high-efficiency incandescent light bulbs, light-emitting diodes and organic LEDs. Already, the company has cut more than 3,000 jobs in the lighting business and closed sites in several countries. The latest round of cuts will involve closing all lighting operations in Rio de Janeiro -- cutting 900 jobs -- and shuttering some lighting positions in the U.S. -- affecting 425 jobs, some of which will be relocated. The company also will transfer some operations in Mexico and the U.S. to other facilities, affecting 80 positions.
