As used in this article, the following terms shall have the meanings indicated:
AVERAGE FOOTCANDLESThe average level of illuminance for a given area measured at ground level with a light meter placed parallel to the ground.
COLOR RENDERING INDEX (CRI)A number from 0 to 100 representing the ability of a light source to accurately reproduce the colors of an illuminated object. (Higher index numbers indicate greater accuracy.)
CORRELATED COLOR TEMPERATURE (CCT)The perceived color of the light emitted by a lamp, expressed in kelvin (K) units. The lower the kelvin rating, the "warmer" or more yellow the light; the higher the rating, the "cooler" or more blue the light.
ESSENTIAL LIGHTINGLight used for a specified period of time that is necessary for a specific purpose, as defined herein, while said purpose is actively being served. This includes fully shielded lighting that is necessary to promote location identification, identify entrances and exits for public circulation, to illuminate walkways in order to promote public safety, and fully shielded security lighting activated by motion sensors and/or timers providing for illumination for a maximum period of 10 minutes per triggering event.
[Amended 7-14-2015 by L.L. No. 22-2015; 5-9-2023 by L.L. No. 18-2023]
EXCESSIVE LIGHTINGLight that exceeds the amount that is needed to perform a visual task at night or is required for safety, per suggested minimum illuminance levels published by IES in its Recommended Practices.
FIXTUREThe complete lighting 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; also referred to as a "luminaire."
FLOOD- OR SPOTLIGHTAny light fixture or lamp that incorporates a reflector, a refractor, or a prismatic lens to concentrate the light output into a directed beam in a particular direction.
FLUORESCENTA type of discharge lamp that employs mercury vapor and phosphors. Unlike incandescent lamps, fluorescent lamps require a ballast to regulate the flow of electricity.
FOOTCANDLEThe unit of measurement used to quantify the amount of light falling on a surface. One footcandle is the illuminance produced by a candle on a surface one foot square from a distance of one foot.
FULL CUTOFFFor the purposes of this article, a "full-cutoff fixture" is considered one that delivers 100% of the total lumens within the 0° to 90° zone with a maximum of 10% of total lumens delivered within the 80° to 90° zone. Full-cutoff fixtures are considered fully shielded. See Figure 1.
[Amended 7-14-2015 by L.L. No. 22-2015]
FULLY SHIELDEDA fixture constructed and installed in a fixed position and in such a manner that all light emitted is projected below the horizontal plane through the fixture's lowest light-emitting part. Unlike a full-cutoff fixture, a fully shielded fixture is not engineered to limit lumen distribution in the 80° to 90° zone. See Figure 1.

GLAREA visual effect produced when a light source within the field of view is brighter than the level to which the eyes are adapted. Glare may cause annoyance, discomfort, loss of visual acuity, or momentary blindness.
HIGH-INTENSITY DISCHARGE (HID) LIGHTINGAn energy-efficient family of lighting that includes high-pressure sodium, mercury vapor, and metal-halide-type bulbs. These types require a warmup time, usually require a ballast exclusive to the light source, and have a higher lumen output per watt than incandescent or halogen lamps.
HIGH-PRESSURE SODIUM (HPS)A type of high-intensity discharge lamp that primarily employs sodium. These lamps produce light with a warm Correlated Color Temperature of approximately 2100 K and have a Color Rendering Index of around 25.

The principal categories are incandescent, fluorescent, low-pressure sodium, high-intensity discharge (HID) (which includes high-pressure sodium, metal halide, and mercury vapor), and LED (light-emitting diode). The categories vary in terms of:

LOW-PRESSURE SODIUMA type of discharge lamp that primarily employs sodium. These lamps have a higher lumen output per watt than HID lamps but low Color Rendering Index.
[Amended 7-14-2015 by L.L. No. 22-2015]
LUMENThe unit of measurement used to quantify the amount of light produced by a lamp or emitted from a fixture (as distinct from "watt," which is a measurement of the electrical power). For the purposes of this article, measurements in lumens shall refer to "initial lamp lumens" (as opposed to "maintained lamp lumens") as rated by the manufacturer when the lamp is new, as listed on the packaging.

NONCONFORMINGLighting which does not meet the requirements and specifications contained in this article.
NONESSENTIAL LIGHTINGLighting which is unnecessary for pedestrian passage or other tasks and therefore not generally useful (i.e., decorative and landscape lighting). This includes lighting intended for a specific task or purpose when said task or purpose is not being actively performed (e.g., parking lot illumination and wall-mounted perimeter lights after business hours).
NONRESIDENTIAL LIGHTINGAny outdoor lighting intended for use on a lot with a business (except home occupation), industrial, or institutional use (or, if undeveloped, is zoned for such use). Municipal buildings and facilities shall follow nonresidential standards.
NUISANCE LIGHTINGAny outdoor lighting that creates a potential hazard to the public, illuminates the interior of a neighboring residential structure from an external point, or creates a light trespass or glare to neighboring properties, thereby causing loss of enjoyment, comfort, or repose.
[Amended 5-9-2023 by L.L. No. 18-2023]
OUTDOOR LIGHTINGLighting that provides illumination to a surface, building, structure, device, or other outdoor feature. Any fixture located indoors that is intended to illuminate something outdoors is considered outdoor lighting for the purposes of this article.
[Amended 7-14-2015 by L.L. No. 22-2015]

REPAIRAny service normally provided by a licensed electrician to a light fixture or lighting installation, including replacement, modification, or relocation of any of the following: poles, mounting arms, wiring, housings, or any component within or attached to a light fixture. Replacement of a user-serviceable lamp (i.e., light bulb) shall not by itself be considered a repair.
RESIDENTIAL LIGHTINGAny outdoor lighting on a lot having a structure or structures whose primary use is residential (or, if undeveloped, is zoned for such use). Although reviewed as a commercial site plan, lighting plans for multifamily or condominium developments shall follow residential standards.
SEARCHLIGHTLighting designed to project a high-intensity beam of light that is typically used to sweep the sky for promotional purposes.
SENSOR (MOTION)A device that causes a light fixture to turn on or off in response to motion or light or infrared radiation or a combination thereof.
SHIELD or SHIELDEDAn opaque device that is attached to a light fixture to prevent light from being emitted in certain directions. Auxiliary "back" or "house-side" shielding added to an already fully shielded fixture can help limit trespass where a fixture is located near the property line.
SKYGLOWThe brightening of the night sky or the overhead glow from artificial light that is directed upward or from light reflected upward from the ground or off other surfaces. Skyglow is caused by the reflection of light off moisture and dust particles in the atmosphere, reducing the ability to view the natural night sky.
SPORTS LIGHTINGLight fixtures used to illuminate courts, arenas, fields, tracks, and recreational areas.
STREETLIGHTINGPermanent outdoor lighting that is owned and maintained by a municipality or other public agency and that is specifically intended to illuminate streets for automotive vehicles and may also incidentally light sidewalks and private property.

UL RATINGA reference to "Underwriters Laboratory," a commercial agency that certifies the maximum safe wattage for fixtures and other electrical devices. A UL label indicating the maximum safe wattage is affixed or imprinted on all light fixtures which are offered for sale.
UNIFORMITY RATIOA ratio that describes uniformity of illuminance across an area. The uniformity ratio may be a ratio of the maximum to minimum illuminance or the average to minimum illuminance.
UNSHIELDEDA fixture designed or installed so that it is not fully shielded, i.e., emits light above the lowest light-emitting part of the fixture.
WATTThe standard unit of measurement of electrical power. One watt is one ampere of current flowing at one volt.
