With the help of wealthy men like J.P.Morgan, Edison set up the Edison Electric Light Company and began his research and development. Edison finally did it in October 1879 with a bulb that used platinum filament, and in 1880, he used carbonized bamboo as an alternative for the filament, which proved to be a key to a long-lasting light bulb. Edison had used vegetables for an alternative for a filament, and he used few than 6,000 vegetable growths from around the world, to find the most suitable filament material. Edison finally decided to try a carbonized cotton thread filament, and when voltage was applied to the completed light bulb, it began to to glow orange. This light bulb lasted fifteen hours, then the filament finally burned
