(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 11 1ux at any property line measured by meter line of sight to any lumenaire. Other than light incidental to fully shielded lighting, no direct light will be allowed to trespass onto other properties.
(3) Island canopy ceiling fixtures shall be recessed so that direct light cannot radiate onto adjacent properties or roadways.
(4) With the exception of flag lighting, ground level signs, any decorative lighting mounted as shielded sconces (emitting a maximum of 3,000 lumens each) on building side walls, no lighting may be pointed in an upward direction.
(5) All commercial 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), industrial and commercial lighting will be designed to achieve no more than a maximum mean average equal to 200% of recommended averages or maximums. Average lux levels in excess of 300% of recommended averages or maximum at ground level will be in non-conformance with this code. Parking lot lighting shall not exceed more than a maximum mean average of 50 lux at ground level.
(6) All outdoor light pole fixtures shall not be taller than the building or 36 feet, whichever is shorter.
(b) Residential uses other than multi-family and trailer park:
(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.
