A. Lamp and Shielding. All permanent light fixtures are required to be full cutoff fixtures with the light source fully shielded for all uses and directed downward, including single-family and multifamily residential uses.
B. Low Pressure Sodium Lighting. Due to their high energy efficiency, long life and spectral characteristics, low pressure sodium (LPS) lamps are the preferred illumination source throughout the Town. Their use is encouraged for outdoor illumination whenever it would not be detrimental to the use of the property.
C. Light Trespass Standard. All light fixtures, including security lighting, shall be aimed and shielded so that the direct illumination shall be confined to the property boundaries of the source. Particular care is to be taken to ensure that the direct illumination does not fall onto or across any public or private street or road. Motion sensing light fixtures shall be fully shielded and properly adjusted, according to the manufacturer’s instructions, to turn off when detected motion ceases.
D. Total Outdoor Light Output Standards. Nonresidential total outdoor light output shall not exceed one hundred thousand (100,000) lumens per net acre for all development except single-family residential uses. This cap is not intended to be achieved in all cases or as a design goal. Instead, design goals should be the lowest levels of lumens necessary to meet the lighting requirements of the site.
E. Total Outdoor Light Output Standards for Single-Family Residential Uses. Outdoor lighting for single-family residential uses is not subject to a lumens per net acre cap, but is subject to the lamp fixture and shielding requirements.
F. Height. Any lighting fixture attached to a structure shall be placed below the eave or parapet, whichever is lower. Different height restrictions may be imposed as a condition of approval by the Planning Commission or Town Council.
G. Commercial Lighting Time Limitations. All nonessential commercial exterior lighting shall only continue in operation until 11:00 p.m. or for as long as the business is open or area is in active use and shall remain off until the business reopens or until daylight the following day. (Exhibit A)].
