Written by Luminaire Fixture is a complete lighting unit consisting of a lamp or lamps together with parts designed to distribute the light, to position and protect the lamps and ballasts (where applicable), and to connect the lamps to the power supply.
Prior to the National Electrical Code® adopting the International System (SI) definition of luminaire, the commonly used term in the United States was and in most instances still is “lighting fixture.” It will take years for the electrical industry to totally change and feel comfortable with the term luminaire.
