I am guessing you are trying to say when did Thomas Edison invent the light bulb. He invented the light bulb on October 22nd, 1879.
It took Thomas Alva Edison 23 trys to invent the light bulb
Thomas Edison is probably most famous for inventing the light bulb, but he also invented the phonograph and a movie camera. See link below for a list of all his patents.
Input to light bulb is Electricity and output is light.
It cuts down on candles manufactured, big maintenance cost, wasted energy when there is heat going off the bulb, it is very fragile-the lightbulb can break very easily in a vibrational environment, they are expensive to replace, a lot of money in energy costs, the light bulb is useless during a power outage, though the main disadvantage is that it is an energy waster
Thomas Edison is credited with inventing the lightbulb.

Light bulb
It took him 10000 triesnearly 40,000 times he failed in inventing a light bulb.
Thomas Edison, not Humphry, is credited with inventing the first commercially practical incandescent light bulb. Edison's light bulb design involved a tungsten filament encased in a vacuum-sealed glass bulb, which could produce light continuously for extended periods. Edison's work on the light bulb was a result of years of experimentation and improvement on previous designs.
December 24,1877 he invented the light bulb.
Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879. However, it's important to note that several inventors, including Sir Joseph Swan, also played a role in the development of the light bulb.
The main problem with Thomas Edison inventing the light bulb is that he did not have enough filament, so he used a different material to replace it.
Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879.
Thomas Edison is wanted for inventing the light bulb.
Nikolai Tesla
Thomas Edison is credited with inventing the light bulb, not "josephswan." Edison's invention of the light bulb in 1879 was a result of years of experimentation with different materials and techniques to create a practical and long-lasting source of light. The invention of the light bulb revolutionized the way people lived and worked by providing a reliable source of illumination.
