Edison and Swan Electric Light Company Edison and Swan Electric Light Company The Edison and Swan Electric Light Company Limited was a manufacturer of incandescent lamp bulbs and other electrical goods. It was formed in 1883 with the name Edison & Swan United Electric Light Company with the merger of the Swan United Electric Company and the Edison Electric Light Company. Thomas Edison established the Edison Electric Light Company in 1878. Joseph Swan established the Swan United Electric Light Company in 1881. In 1882 the American Edison Company of Thomas Edison sued Swan, claiming infringement of Edison's U.S. patent of 1879; however, they never made it
Thomas Edison flaws as an extremely short life, high expense to produce, and high electric current drawn, making them difficult to apply on a large scale commercially. Edison realized that to connect a series of electric lights to an economically manageable size and using the necessary thickness of copper wire, he would have to develop a lamp that used a low amount of current. This lamp must have high resistance and use relatively low voltage (around 110 volts). After many experiments, first with carbon filaments and then with platinum and other metals, Edison returned to a carbon filament. The first successful test
