Although over a hundred years has passed since that day modern incandescent light bulbs are very similar to edison s groundbreaking model. In 1809 the first incandescent light bulb was created by an english chemist sir humphry davy by connecting wires and a piece of carbon to a battery. When he connected wires to his battery and a piece of carbon the carbon glowed producing light.
Where edison succeeded and surpassed his competition was in developing a practical and inexpensive light bulb according to the doe. In 1802 humphry davy invented the first electric light.

His inventions included the phonograph the incandescent light bulb and one of the earliest motion. Electric arc lighting invented in 1809 was much safer but far too bright for use in a small area.
Thomas alva edison improved the bulb after lots of experiments with different filaments in 1879 and produced a bulb that could glow for over 1500 hours. The carbon glowed and thus light was produced. Carbon filament bulbs the first electric light bulbs became available commercially in 1879.
Thomas edison didn t invent the light bulb but he did make it better. Even though he didn t dream up the first light bulb ever crafted and technology continues to change every day edison s work with light bulbs was a spark of brilliance on the timeline of invention. Light bulbs with a carbon filament were first demonstrated by joseph swan in february 1879 and by edison in october 1879.
