1879 Thomas Edison and Joseph Swan patent the carbon-thread incandescent lamp. It lasted 40 hours. 1880 Edison produced a 16-watt lightbulb that lasts 1500 hours. 1882 Introduction of large scale direct current based indoor incandescent lighting and lighting utility with Edison's first Pearl Street Station
Lodygin's lamps. He invented an incandescent light bulb before Thomas Edison, but it was not commercially profitable. The lamp with a tungsten filament is indeed the only design used now, but in 1906 they were too expensive. Several Lodygin's ideas were implemented much later, even after his death.
Its continuous operation has largely eliminated the stresses associated with turning a light bulb on and off, the act of which causes the temperature of the bulb to increase and decrease. The bulb was made by hand, using a carbon filament (of greater thickness and strength than the tungsten filaments used in most modern lightbulbs) along with ...
