The first practical incandescent light bulb. Edison and his team of researchers in Edison's laboratory in Menlo Park, N.J., tested more than 3,000 designs for bulbs between 1878 and 1880. In November 1879, Edison filed a patent for an electric lamp with a carbon filament.
Thomas Edison did not invent the light bulb that was Warren de La Rue . Edison didn't even invent the carbon filament in the bulb, that was Joseph Swan. Edison purchased the patents and commercialized it. His first invention was the phonograph - he abandoned that for others to improve and commercialize.
because if he didn't make the light bulb we would be living in the dark and the only source of light would be daylight
There are a number of discoveries and works that are credited to Thomas Edison. Some of them include the motion picture camera, electric light bulb, phonograph and so many more.
I'm sorry to say that he didn't In 1878 Joseph Wilson Swan, an English physicist and Chemist received a patent for his invention and his house was the first in the world to be lit by electric light. See Swan's Wikipedia entry Thomas Edison,upon seeing the British patent,or open letter, made copies and publicised his work. Swan was keen to make money from his invention and decided set up a joint venture which became the 'Ediswan' company in 1883. I am sure the name Swan would not have figured in the name unless Edison was forced to retract his claim of prior invention. Edison did produce an efficient steam driven DC dynamo known as' Long Waisted Annies' to drive his lamps and famously lit the road out side his workshop. This the likely source of your error.
