Is Thomas Edison’s light bulb still lit?
By January 1879, at his laboratory in Menlo Park, New Jersey, Edison had built his first high resistance, incandescent electric light.

How long do filament bulbs last?
about 1,000 to 2,000 hours
In the United States, the average incandescent light bulb (that is, a bulb heated with a wire filament) has a lifespan of about 1,000 to 2,000 hours. Light emitting diode (LED) bulbs, which are increasingly replacing incandescent bulbs, are said to last between 25,000 and 50,000 hours — an incredible bump.
