(a) The following exterior lighting shall be permitted in any use district:
(1) In any use district, light sources with lamps rated at a total of not more than fourteen hundred (1,400) lumens shall be permitted, except for flood or spotlights.
(2) Flood or spot lights used for the external illumination of buildings or signs with lamps rated at one thousand (1,000) lumens or less, shall be permitted in any use district provided that such lighting is not aimed, directed or focused toward residential districts or uses or toward a public street so that there is no interference with the vision of persons on public streets or in residential districts.
(3) Exterior lighting with lamps more than one thousand (1,000) lumens will be permitted provided that the light source is down-lit to reduce intensity and glare and is so arranged as to reflect lights away from all adjacent residential districts or uses and from adjacent public streets. Furthermore, the light diffusing media shall be totally shielded with opaque material on the top and all sides and the light source shall be parallel to the horizontal plane of the area to be lighted.
(4) Security lighting that is controlled by a motion detector and which does not remain on longer than ten (10) minutes after activation shall be permitted in any use district, provided that such lighting is not aimed, directed or focused toward residential districts or uses or toward a public street so that there is no interference with the vision of persons on public streets or in residential districts.
(b) Permitted exterior lighting in any use district shall be subject to the following conditions:
(1) Exterior lighting shall not cause luminance that is greater than one (1) foot- candle within two (2) feet of the wall of any main building in an adjacent or nearby R-1 through R-5 or RM district.
(2) All illumination of signs and any other outdoor features shall not be of a flashing, moving, or intermittent type. Artificial light shall be maintained stationary and consistent in intensity and color at all times when in use.
(3) When the abutting district is an R-1 through R-5 or RM district, the distance between the structure supporting the light source and the property line of such zoning district shall not be less than the distance between the top of the light source and the ground below the structure or building to which the light is attached.
(4) The distance between the top of any light source and the ground below the structure shall not exceed the following, in each use district:

(5) Structures that support lighting fixtures, other than signs, may be permitted in any yard where off-street parking lots are permitted.
(6) Under-canopy lighting (such as gas station pump canopies) shall be flush mounted to provide down lit illumination and shall not be of such intensity as to cause interference with vision of persons on public streets or in residential districts.
