The purpose of street lighting is to ensure public safety and welfare and to protect the night sky. Street lighting shall meet the following standards unless otherwise permitted or restricted by this ordinance.
.1 Street lights shall in all cases use fully shielded fixtures except that decorative street light fixtures shall be designed with caps so that light does not shine upward at more than a 135-degree angle measured above straight down (three-quarters of the way between straight down and straight to the top) from the pole or mounting wall.
.2 Fixtures with minimal across-road and "house side" waste shall be used, especially in residential areas, taking into consideration the details of roadway geometry and width.
.3 Low pressure sodium lights are strongly encouraged.
