A.

Exterior Lighting Standards.

1.

Purpose. The purpose of this section is to regulate the spillover of light and glare on motorists, pedestrians, and adjacent land uses from a commercial use light source. With respect to vehicles, the primary purpose of this section is to protect public safety. In other cases, both the nuisance and hazard of careless lighting require regulation.

2.

Standards. Any lighting used to illuminate an off-street parking area, sign or other structure, should be arranged as to deflect light away from any adjoining residential zone or from the public streets. Direct or reflected glare, whether from floodlights or from high temperature processes such as combustion or welding, should not be directed into any adjoining property. The source of lights should be hooded or controlled in some manner so as not to light adjacent property. Bare incandescent light bulbs should not be in view of adjacent property or an adjacent public right-of-way.

3.

Commentary. This regulation represents the minimal standard for exterior lighting. The developer or property owner should evaluate the following circumstances:

a.

No cutoff luminaire. When the light source has no cutoff, exterior lighting fixtures can produce unsightly glare which may result in a safety hazard. (A cutoff is the point at which all light emitted from a light is completely eliminated-cutoff at a specific angle to the ground.)

b.

Less than 90-degree cutoff luminaire. These lights are preferable because the design of the fixture can ensure that the light source is not visible off site.
