Where did Thomas Edison invent the light bulb?

Answer 1

Edison did not invent the first electric light bulb, but instead invented the first commercially practical incandescent light.

Thomas Edison and his team invented the incandescent lamp in his laboratory in Menlo Park, New Jersey.

Thomas Edison's greatest challenge was the development of a practical incandescent, electric light. Contrary to popular belief, he didn't "invent" the lightbulb, but rather he improved upon a 50-year-old idea. In 1879, using lower current electricity, a small carbonized filament, and an improved vacuum inside the globe, he was able to produce a reliable, long-lasting source of light.

The first person to create a light bulb was Warren de la Rue who demonstrated one in 1840.
