What is a luminaire?

Thursday, July 12, 2018

A luminaire is what an installed electric light fixture is called in the building code and electrical textbooks. The dictionary definition is “a complete electric light unit; used especially in technical texts.” It is an early 20th century word of French origin.
    An electrician will know exactly what you mean if you use this this word, mainly because it is used in the electrical code and licensing tests, but will probably use a more specific description like “track light” or “chandelier” when talking with you about your home. You may also see it used on the side of the packing box for a light fixture.
