1. Security Lighting: Security lighting shall use the lowest possible illumination to effectively allow surveillance, be shielded, and directed downward toward designated areas. The use of motion sensors, timers, photocells or other means to activate lighting during times when it is needed is encouraged to conserve energy, provide safety, and promote compatibility between different land uses. However, photocells are permitted only at primary entrances to a building and where the light source is fully shielded. Security lighting illuminance levels shall be a maximum of ten (10) foot-candles.
2. Signage Illumination: All signage shall comply with chapter 15 of this title. Signage utilizing lighting shall have fixtures mounted to the top of the sign structure and aimed downward onto the sign from above. Fixtures shall be fully shielded so that light is directed only onto the sign face and not aimed at the sky, adjacent streets, roads or properties. Luminance shall not exceed nine (9) foot-candles or one hundred (100) nits (one hundred (100) candelas per square meter) during the first hour after sunset, and lighting must be fully extinguished one (1) hour after sunset or within one-half (1/2) hour of the end of normal business hours, whichever is later.
3. Overhead Walkway Lighting: Overhead walkway lights shall be installed on a black or gray wire or metal rod, not to exceed three thousand kelvins (3,000 K) nor a maximum of eight hundred fifty (850) total lumens across the property or area. Overhead walkway lighting may not be located in any location that is wider than 32 feet. Overhead walkway lighting shall not blink, flash, or rotate, nor create a hazard or nuisance from glare. Overhead walkway lighting shall be maintained in safe and good working conditions at all times.
