§ 85-867. Illuminance and type of lamp for all nonresidential exterior lighting.

A. 

Permissible luminaire location and effects.

(1) 

No luminaire shall be located or concentrated so as to produce glare or direct illumination across the boundary property line, nor shall any such light be of such intensity as to create a nuisance or detract from the use and enjoyment of adjacent property. See Table 1 and Table 2 for setback, height, and maximum light output recommendations for guidance.

(2) 

The maximum illuminance at or beyond the property line that adjoins a residential parcel or public right-of-way may not exceed 0.05 footcandle horizontal on the ground or 0.05 footcandle vertical measured at a five-foot height above the ground, unless another applicable law supersedes. Maximum horizontal or vertical illuminance allowed between adjacent commercial properties is 0.1 footcandle.

B. 

Permissible levels of illuminance.

(1) 

The average illuminance levels listed in the Illumination Levels for Various Common Tasks, as provided in Table 3, shall not be exceeded for nonresidential exterior lighting unless otherwise specified or approved by the reviewing board, department, division or agency of the Town of Brookhaven.

Editor's Note: Table 3 is included as an attachment to this chapter (see Attachment 8).

(2) 

The Town of Brookhaven recognizes that not every situation will require lighting, including situations which may utilize the installation of reflectorized markers, lines, signs or other passive means, and excessive or unnecessary light shall be avoided.

(3) 

Illuminance level measurements for parking lots, sidewalks, and other walkways shall include light contributions from nearby side-mounted building lights, freestanding sidewalk lights affected by side-mounted building lights, and streetlights.

(4) 

In no instance may any lighted surface, as installed, except for municipal athletic fields, exceed the maximum values listed in Table 3 for the appropriate task, as measured horizontally or vertically by a light meter.

C. 

High-pressure sodium, compact fluorescent, or low-pressure sodium shall be used for all light sources rated over 1,800 lumens (100 watts incandescent). Metal halide (MH) rated over 3,000K and mercury vapor (MV) light sources are not permitted.
