What is an incedescent?

An incandescent is a type of light produced by heating a material until it glows, typically referring to incandescent light bulbs. These bulbs contain a thin filament, usually made of tungsten, that emits light when an electric current passes through it, heating the filament to a high temperature. While they provide warm, pleasant light, incandescent bulbs are less energy-efficient compared to modern alternatives like LED or CFL bulbs.
