lamp bulb

Screws into socket

A lamp bulb is the replaceable light-producing component of a lamp—the glass enclosure containing a filament, gas, or LED that emits light when powered.

The term distinguishes it from bulbs used in ceiling fixtures or appliances: I need to pick up a lamp bulb for the reading light.
