A. Security Lighting should use the lowest possible illumination to effectively allow surveillance. Illumination standards are set forth in RZC 21.34.120, Mounting and Illumination Standards Table, of this chapter.

B. All security lighting fixtures shall be full cutoff fixtures as defined by the Illuminating Engineering Society of North America (IESNA).

C. Security lighting shall be shielded and aimed so that illumination is directed to the designated areas.

D. Where a proposed security lighting application is not identified in RZC 21.34.120, Mounting and Illumination Standards Table, of this chapter, the table shall be used as a guide for establishing the range of permissible light levels.

E. Where a guardhouse or other manned security enclosure is used to provide security at a site, all security lighting shall be dimmable to lower levels at night in order to allow visibility from the guardhouse or security enclosure.
