Lamp or Luminaire?
Lamp, illuminant, luminaire – which is which?
Lamp, illuminant, luminaire: Three terms everyone gets mixed up. But which is which?
The short answer: A lamp is the illuminant in a luminaire!
People often call a lamp a bulb. That is because of the shape of the traditional "light bulb", but it is not an official term. Lamps – meaning illuminants – are used in all popular technologies. However, all of them are now trending towards LED.
By the way: The terms table lamp and floor lamp are actually incorrect. Instead, table luminaire and floor luminaire would be the correct terminology.
