On 31 December 1879 Thomas Edison publicly demonstrated a practical incandescent electric lamp at his Menlo Park, New Jersey, laboratory, where his team had developed a carbon-filament bulb that burned for many hours; special trains brought spectators to see the buildings illuminated.
Edison's true breakthrough was systemic: he conceived not merely a bulb but an entire integrated system of generation, distribution, metering, and lighting. On 4 September 1882 his Pearl Street Station in lower Manhattan began supplying direct-current electricity to paying customers in a district of New York City, the first permanent commercial central power station for incandescent lighting. This marked the start of electric utilities as an industry and of electrification as a transformative force in modern life. Electric lighting extended productive hours, improved safety, and reshaped factories, homes, streets, and cities. The model of centralised generation feeding distributed consumers became the template for electric power worldwide. Edison's work, building on Faraday's principles and many predecessors, helped launch the second industrial revolution and a century of expanding electrical infrastructure.
