The light bulb was being used inside of Tesla's laboratory long before Edison "invented" it. Electric current was also being used many years before Edison started playing with the incandescent light bulb.
Edison made the light bulb cheaper and offer us a method of using power on a larger scale. Unfortunately, his concept was dwarfed by the far superior system invented by Westinghouse and Tesla.
Edison picked direct current as the generation system while Tesla's was alternating current. The winning system was A.C. Edison's never took off because power could not be transferred over any distance with D.C.
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. So he said. Tesla worked for Thomas Alva Edison for 1 year At that time, the most important "inventor" in the world was named Thomas Alva Edison-the so-called wizard of Menlo Park.... Edison was credited with the invention of the DC dynamo and the electric light bulb . . . but the only thing he really invented was the ELECTRIC CHAIR!!
