A luminaire is defined as “a complete lighting unit consisting of a lamp or lamps together with the parts designed to distribute the light, to position and protect the lamps and ballast (where applicable), and to connect the lamps to the power supply.” Since luminaries (lighting fixtures) were not previously defined, this new definition is meant to cover all aspects of a lighting unit, including the lamps that actually provide the illumination, as well as internal and external parts necessary for the proper operation of the unit. Luminaries can be of the traditional type, such as a recessed or surface-mounted incandescent, fluorescent or other electric-discharge luminaries. Luminaries can also be of the non-traditional type, such as fiber optics with the light source at one location and the fiber core or “light pipe” at another.
