What “lightbulb” means
Wiktionary · Wikipedialightbulb
- nounAn evacuated glass bulb containing a metal filament which is heated by electrical resistance to produce light.
An electric light, lamp, or light bulb is an electrical device that produces light from electricity. It is the most common form of artificial lighting.

The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet mount.
