(a) ARCHITECTURAL LIGHTING: Luminaires provided to enhance features of the architectural design of a structure.
(b) FIXTURE: The assembly that houses the lamp or lamps; and can include all, or some of the following parts: a housing, a mounting bracket or pole socket, a lamp holder, a ballast, a reflector, or mirror, and/or a refractor or lens.
(c) FOOT-CANDLES (fc): A quantitative unit measuring the amount of light (illumination) falling onto a given point, one footcandle equals one lumen per square foot.
(d) GLARE: The effect produced by a light source within the visual field that is sufficiently brighter than the level to which the eyes are adapted, to cause annoyance, discomfort, or loss of visual performance and ability.
(e) HEIGHT OF LUMINAIRE: The height of a luminaire shall be the vertical distance from the ground directly below the centerline of the luminaire to the lowest direct light emitting part of the luminaire.
(f) HIGH LEVEL ACTIVITY PARKING LOTS: These are parking lots in which most of the parking spaces will be occupied by customer vehicles after 6:00 p.m.
(g) LAMP: The component of a luminaire that produces the actual light.
(h) LOW ACTIVITY LEVEL PARKING LOTS: These are parking lots in which most of the parking spaces will be occupied by employee vehicles, with very few parking spaces occupied by customer vehicles after 6:00 p.m.
(i) LUMEN: A quantitative unit used to identify the amount of light emitted by a light source. A lamp is generally rated in lumens.
(j) LUMINAIRE: A complete lighting system and includes a lamp or lamps and a fixture.
(k) MAINTAINED FOOT-CANDLES: Illuminance of lighting fixtures adjusted for a maintenance factor accounting for dirt buildup and lamp output depreciation. The maintenance factor used in the design process to account for this depreciation cannot be lower than 0.72 for high pressure sodium and 0.64 for metal halide and mercury vapor.
(l) MEDIUM ACTIVITY LEVEL PARKING LOTS: These are parking lots in which most of the parking spaces will be occupied by employee vehicles, but with significant parking spaces occupied by customer vehicles after 6:00 p.m.
(m) OUTDOOR LIGHTING: The nighttime illumination of an outside area or object by any manmade device located outdoors that produces light by any means.
