ARCHITECTURAL LIGHTING: | Outdoor lighting directed at buildings, facades, structures, monuments, and other architectural features. |
BACKLIGHT: | For an exterior luminaire, lumens emitted in the quarter sphere below horizontal and in the opposite direction of the intended orientation of the luminaire. For luminaires with symmetric distribution, backlight will be the same as front light. |

BUG: | A luminaire classification system that classifies backlight (B), up light (U) and glare (G). |
BUILDING LIGHTING: | All luminaires mounted on or used to illuminate the exterior of a building, including any luminaires under the roofline. |
CANOPY: | A roofed structure that is open on at least three sides and typically provides protection from the sun or weather, which is associated with the sale of commercial goods or services. |
CANOPY LIGHTING: | All luminaires mounted to and used to illuminate the area under a canopy. |
CORRELATED COLOR TEMPERATURE: | Specification of the color appearance of the light emitted by a lamp, relating its color to the color of light from a reference source when heated to a temperature, measured in degrees Kelvin (K). |
CURFEW: | A time defined by the authority when outdoor lighting is reduced or extinguished. |
EMERGENCY EGRESS LIGHTING: | A battery-backed lighting device designed to come on automatically when a building experiences a power failure or emergency. |
FULLY SHIELDED: | A light fixture constructed and mounted such that all light emitted by the fixture, either directly from the lamp or indirectly by reflection or refraction from any part of the light fixture, is projected below the horizontal. If the lamp, any reflective surface, or lens cover (clear or prismatic) is visible when viewed from above or directly from the side, from any angle around the fixture, the fixture is not fully shielded. |
GLARE: | A visual disturbance produced by a distinct light source within the visual field that is sufficiently brighter than the level to which the eyes are adapted. |
HARDSCAPE: | Permanent hardscape improvements to the site including parking lots, drives, entrances, curbs, ramps, stairs, steps, medians, walkways and non-vegetated landscaping that is 10 feet or less in width. |
ILLUMINANCE: | The amount of visible light, as measured in lumens, falling onto a unit of surface area, correlating to the perception of brightness by the human eye. |
INSTALLED HEIGHT: | The height above average finished grade of the lowest point on an installed luminaire. |
KELVIN: | A unit increment of temperature and is used as a color temperature scale of a light bulb (symbol "K"). |
LAMP: | The source of light being emitted from a luminaire, such as a bulb. |
LANDSCAPE LIGHTING: | Outdoor lighting directed at trees, shrubs, plants, flower beds, fountains, gardens, and other natural or landscaped features. |
LIGHT: | Electromagnetic radiation within a range of wavelengths enough for visual perception by the normal, unaided human eye. |
LIGHTING INSTALLATION: | An arrangement of one or more luminaires, including any mounting hardware, brackets, and supporting structures. |
LOW VOLTAGE LANDSCAPE LIGHTING: | Landscape lighting powered at less than fifteen (15) volts and limited to luminaires having a rated initial luminaire lumen output of five hundred and twenty-five (525) lumens or less. |
LUMEN: | The unit used to measure the amount of light which is produced by a lamp. |
LUMINAIRE: | An individual lighting assembly, including the lamp and any housings, reflectors, globes, lenses, shields or other components designed to block or distribute light. |
MANUFACTURER'S CUT SHEET: | A description of each luminaire identified in the site plan, including the manufacturer, part number, model number, a photograph or catalog cut, correlated color temperature (CCT), photometric data verifying any compliance requirements specified within this Chapter 19, light output in initial lumens, shielding or glare reduction devices, lamp type, on/off control devices and the location of each luminaire as identified in the site plan. |
MOTION-ACTIVATED SENSOR: | A sensor which causes a luminaire to become illuminated automatically upon the presence of motion or infrared radiation or a combination thereof within its field of view. |
NEON LIGHT: | Brightly colored light generated by using electric current to excite a gas or gas mixture (including neon, argon, helium, or other gases) typically contained in a tube which can be bent into various forms for use as decoration or signs. For the purposes of this Part 20, fluorescent tubes are not considered neon light. |
NONCONFORMING USE: | Any use which was legally established prior to the effective date of this Chapter 19, or subsequent amendment to it, and which would not be permitted to be established as a new use in the zone in which it is located by the regulations of this Chapter 19. |

OUTDOOR ATHLETIC FIELD: | An open outdoor field, court, or track or similar facility used for athletic activity or playing sports such as baseball, soccer, football, tennis, skate park, volleyball, and basketball. |
OUTDOOR LIGHTING: | Light generated from an indoor or outdoor source that provides illumination to a surface, building, sign, structure, device, or other outdoor feature which is visible to an observer located outdoors. |
PARKING LOT LIGHTING: | All luminaires used to illuminate the parking lot. |
PHOTOMETRIC PLAN: | An illuminance grid plan for multi-fixture lighting installations that demonstrates compliance with all applicable requirements set forth in this Chapter 19. |
SEARCHLIGHT: | A lighting installation designed to project a high-intensity beam of approximately parallel rays of light that is typically used to sweep the sky for promotional purposes. |
SINGLE-PURPOSE EMERGENCY EGRESS LIGHTING: | A battery-backed lighting device designed to come on automatically when a building experiences a power failure or emergency. A single-purpose fixture can only be used for the sole purpose of emergency egress lighting. It shall not be considered as exempt from the provisions of this Chapter 19 when used as a dual-purpose fixture. |
STREET LIGHTING: | One or more luminaires or light installations designed to illuminate a public roadway or intersection. |
TEMPORARY HOLIDAY DECORATION LIGHTING: | Festoon type lights, limited to small individual bulbs on a string, where the spacing of bulbs is not closer than three inches and where the output per bulb is no greater than fifteen (15) lumens.

Temporary lighting may not exceed ninety (90) days annually. |
TEMPORARY LIGHTING: | Lighting installed and operated for periods not to exceed sixty (60) days, completely removed and not operated again for at least thirty (30) days. Temporary lighting may not exceed ninety (90) days annually. |
UPLIGHT: | Lighting applications which direct light above a horizontal plane. |
