incandescent bulb
Edison's glowing invention
An incandescent bulb is a light source that produces illumination by heating a filament until it glows.
Electricity passes through a thin wire, typically tungsten, enclosed in a glass bulb filled with inert gas.
Once the dominant form of electric lighting, incandescent bulbs have largely been replaced by more efficient LED and fluorescent alternatives: The old incandescent bulbs gave off a warm glow.
