Edison began his career as an inventor in Newark, New Jerseywith the automatic repeater and his other improved telegraphic devices, but the invention that first gained him wider notice was the phonograph in On 17 JanuaryLatimer received a patent for the "Process of Manufacturing Carbons", an improved method for the production of light bulb filaments, which was purchased by the United States Electric Light Company.

Edison did not demonstrate a mature product until Today, light bulb manufacturers have managed to make CFL bulbs with a wider range of light quality, and many of them are indistinguishable from traditional incandescent light bulbs.
