Oct 21, 2024 · Thomas Edison perfects the first commercially practical incandescent light bulb. Using a filament of carbonized cotton thread, his first attempt at this design results in a bulb that lasts about 13.5 hours before burning out. He later extends the life of the bulb to 40 hours.
Hot off the success of his phonograph, Thomas Edison has his sights set on the light bulb. He figures he and his team of 40 researchers can come up with a functioning incandescent bulb in three or four months.

Early electric light experimentation dates back as far as 1802, with many other inventors working on the task prior to, during, and after Edison’s own work.
British physicist and chemist Joseph Swan and American inventor Thomas Edison demonstrated the first instances of commercial production of incandescent lamps. Although Swan began experimenting with incandescent light bulbs earlier, it was Edison’s design which was ultimately adopted.
Commercial production of incandescent lamps was delayed by the lack of a sufficient vacuum pump and of an efficient filament. By the late 1800s an adequate vacuum pump and sufficient filament was developed independently by Swan (1878) and Edison (1879). By 1880 both men had applied for patents for their designs, and litigation between them eventual...

The bulb was able to produce light for up to 13.5 hours, which was an improvement over previous versions of the light bulb. Joseph Swan's light bulb did not succeed commercially, but it brought us a step closer to the modern light bulb. Thomas Edison is often credited with inventing the first light bulb.
Mar 13, 2018 · Edison was able to produce over 13 continuous hours of light with the cotton thread filament, and filed his first light bulb patent on January 27, 1880. Later, he and his researchers found that the ideal filament substance was carbonized bamboo, which produced over 1,200 hours of continuous light.
