An incandescent light bulb is a type of electric light source that produces light by heating a filament made of tungsten until it glows. When electric current passes through the filament, it heats up to a high temperature (typically around 2,200 to 3,000 degrees Fahrenheit or 1,200 to 1,600 degrees Celsius), causing it to emit visible light.
