GE Lighting’s Sylvester Says LEDs May Be 80% of Market by 2020

General Electric Co. expects most light bulbs, including the incandescent invented by founder Thomas Edison, to be replaced within a decade by light-emitting diodes that can last from a child’s birth through college.

“People are starting to talk about LEDs for general lighting for indoors,” Maryrose Sylvester, who was appointed head of the lighting unit in March, said in an interview in New York. “By 2020, about 70 to 80 percent of the general lighting market is going to be enabled by LEDs.”
