But what are light bulbs, really? The incandescent light bulb is a sealed glass globe containing within its vacuum thin metallic filaments through which electric currents pass. This process produces the heat which then results in the light.

Although it is Thomas Edison who is commonly credited with having invented the incandescent light bulb, he was, in fact, the one who only perfected it. Historians now attribute the invention of the incandescent light bulb to 22 individual inventors.
