Thomas Edison perfects the first commercially practical incandescent light bulb using a filament of carbonized cotton sewing thread at his laboratory in Menlo Park, New Jersey. His first new bulb lasts approximately 13½ hours before burning out, but in subsequent tests, the life of the bulb in increased to forty hours. The idea of electric lighting isn’t new, several people had worked on and even developed forms of electric lighting, such the arc lamp. However, no current light method is practical for residential use.

The discovery comes after Edison tested over six thousand vegetable fibers, including bamboo, baywood, boxwood, hickory, cedar, and flax, for suitability. It required eighteen months of work, US$40,000, and 1,200 experiments.
