What is the difference between lights and lamps?

Colloquially, they are often equated with each other. However, lighting experts make a clear distinction between lamps and luminaires.

This also applies to LEDs. A lamp is the typical light source (e.g. a light bulb) that is screwed into the socket of a luminaire. That already explains it. Luminaire is the system consisting of lamp, base, lampshade, etc. LED luminaires are available with a replaceable LED light source (lamp) and with a permanently installed LED module.
