2. Light shielding.
a. Any light source or lamp that emits more than 375 lumens (25 watt incandescent or 7 watt compact fluorescent) shall be concealed or shielded with an Illuminations Engineering Society of North America (IESNA) full cut-off style fixture with an angle not exceeding 90 degrees to minimize the potential for glare and unnecessary diffusion on adjacent property. Figures 4.05-1 and 4.05-2 illustrate examples of shielded fixtures and Figures 4.05-3 and 4.05-4 illustrate light trespass.
Figure 4.05-1 (Light Shielding Illustration): Fully shielded
Figure 4.05-2 (Light Shielding Illustration): Not fully shielded
Figure 4.05-3 (Light Trespass Illustration): Does not comply – Light trespass
Figure 4.05-4 (Light Trespass Illustration): Complies – No light trespass
