Exhibit 5
bit 5: This is a tool for aiming lights such as the floodlight represented in Exhibit 4. This tool would verify the angle of 20º by placing
r edge of the tool against the floodlight lens and adjusting the floodlight so that a level parallel to the bottom edge shows level.
F.
With the exception of lighting which is required for security and safety such as parking lot illumination, busin

For lighting horizontal tasks such as roadways, sidewalks, entrances and parking areas, fixtures must meet
cutoff" criteria (no light output emitted above ninety (90) degrees at any lateral angle around the fixture).
Intermittent lighting must be of the "motion sensor" type that stays on for a period of time not to exceed five
minutes and has a sensitivity setting that allows the luminaire to be activated only when motion is detected
site.
All trespass lighting shall not exceed two and one-half (2½) foot-candles measured at the property line, exc
residential trespass lighting is regulated in subsection b(5)A above.
Floodlight fixtures must be aimed so as to prevent direct radiation of light into the open sky at any angle abo
horizontal plane as shown in Exhibit 4 and verified using a tool such as shown in Exhibit 5.
B.
Outdoor sales and service station canopies must utilize canopy lights that are fully recessed into the canopy
fully shielded by the canopy.
The following average maintained illuminance levels for service stations must not be exceeded:
