tungsten bulb
Filament lamp type
A tungsten bulb is an incandescent light bulb with a filament made of tungsten, a metal that can withstand extremely high temperatures without melting.
When electric current passes through the filament, it glows white-hot and produces light.
Tungsten bulbs dominated household lighting for over a century before being largely replaced by more energy-efficient LEDs: The old tungsten bulbs gave the room a warm glow.
