XIII-A MLOD-1 MILITARY LIGHTING OVERLAY DISTRICT
FULLY SHIELDED - A lighting fixture constructed in such a manner that all light emitted by the fixture, either directly from the lamp or a diffusing element, or indirectly by reflection or refraction from any part of the luminaire, is projected below the horizontal plane as determined by photometric test or certified by the manufacturer. A fully shielded fixture is not necessarily full cutoff.
GLARE - A luminance produced by bright sources in the field-of-view superimposed on the image in the eye reducing contrast and hence visibility.
"IESNA" (or "IES") - An acronym for the Illuminating Engineering Society of North America. The IESNA make recommendations for outdoor lighting but does not set outdoor lighting community standards which are set through local regulations.
ILLUMINANCE - The quantity of light arriving at a surface measured in foot-candles.
INTERMITTENT LIGHTING - Luminaires that do not remain on for more than five (5) minutes.
LUMEN - A unit of luminous flux. For purposes of this Section, the lumen-output values shall be the initial lumen output ratings of a lamp. The lumen rating associated with a given lamp is generally indicated on its packaging or may be obtained from the manufacturer.
LUMINAIRE - A complete lighting fixture consisting of a lamp or lamps together with the parts designed to distribute the light, to position and protect the lamps to connect the lamps to the power supply.
LUMINOUS FLUX - A quantitative expression of the brilliance of a source of visible light which is electromagnetic energy within the wavelength range of approximately three hundred ninety (390) nanometers (nm) to seven hundred seventy (770) nm. This quantity is measured in terms of the power emitted per unit solid angle from an isotropic radiator, a theoretical point source that radiates equally in all directions in three-dimensional space.
NADIR - The direction pointing vertically down from the lowest light emitting part of the luminaire (see Exhibit 2 for an example).
NIT - A unit of illuminative brightness equal to one (1) candle per square meter, measured perpendicular to the rays of the source.
OUTDOOR LIGHTING - Illumination of an outside area or object by any man-made device that is located outdoors and produces light.
TEMPORARY OUTDOOR LIGHTING - Lighting allowed as specified in an approved temporary permit pursuant to the requirements of Subsection (D)(12)(h) below.
TRESPASS LIGHTING - Light emitted by a luminaire that falls outside the boundaries of the property on which the luminaire is sited.
