Thomas Edison's light bulb was developed in the 1880's. It was a very difficult project, but payed off once it was created. He ended up with over 10000 patents to every single one of the various things that he tried.
The components to the lightbulb were the hardest part of the project. He spent countless hours testing thousands of different filaments to see which filaments burned the brightest and for the longest time. He tested over 6000 different natural materials and every different type of metal. Many filaments would dissolve or burn out almost immediately. He found that carbon was one of his best options and used that a lot.
The light bulb that Thomas Edison had created was complicated. It was based on the idea of the incandescent lamp. No one had been successful in creating an incandescent lamp before, although many people had attempted and failed at creating it. The light works by sending an electric current through a piece of filament, housed inside of a glass bulb to create a vacuum. Two wires would be connected to both of the sides of the filament creating a circuit where the electricity could flow freely through the filament causing it to heat and glow.
