(a) Outdoor lighting fixtures installed in commercial, manufacturing, residential and mufti-family districts shall comply with the following:
(1) Where used for safety or security purposes, only fully shielded lumenaires shall be utilized.
(2) The cut-off angle or placement of all lumenaires will be such that the level of lighting shall not exceed eleven lux at any property line measured by meter line of sight to any lumenaire. No direct light will be allowed to trespass onto other properties other than light incidental to fully shielded lighting (Ref. Figure 4).
(3) Island canopy ceiling fixtures shall be recessed or shielded so that direct light cannot radiate onto adjacent properties or roadways (Ref. Figure 5).
(4) With the exception of flag lighting, ground level signs, and decorative lighting mounted as shielded sconces (emitting maximum of 3,000 lumens each) on building side walls, no lighting may be pointed in an upward direction (Ref. Figure 6).
(5) All lighting will be designed to provide average lux levels at ground level in keeping with the recommended averages published in RP-33 Lighting for Exterior Environments and RP-20 Light for Parking Facilities by the IESNA (Illuminating Engineering Society of North America). All lighting will be designed to achieve no more than a maximum mean average equal to 200% of recommended averages or maximum. Actual average lux levels in excess of 300% of recommended averages or maximum at ground level will be in non-conformance with this code.
(6) Parking lot lighting shall not exceed more than a maximum mean average of fifty lux at ground level. Immediately after installation, actual average lux levels in excess of seventy lux will be in non-conformance with this code.
(7) No outdoor light pole fixtures shall be taller than the principal building on the lot or thirty-six feet, whichever is shorter.
(8) Light fixtures used to illuminate flags, statues, or any other objects mounted on a pole, pedestal, or platform, shall use a narrow cone beam of light that will not extend beyond the illuminated object (Ref. Figure 7).
(b) Residential uses other than mufti-family:
(1) All HID Lighting (including mercury vapor) will have full cut-off fixtures or be shielded to prevent the trespass of glare from direct light onto adjacent properties.
(2) All spot or flood lighting will be shielded or aimed in such a way as to not direct light to trespass onto other residential properties.
