Have no luminaire, of 50watts or greater, withuplight or show that lessthan 5% of light emittedby all exterior luminairesreaches the night sky onan annual basis.

The direction of maxintensity for all interiorluminaires must fallwithin the building (notstriking a window).

The direction of maxintensity for all exteriorluminaires must fallwithin the property.

Shield all luminaires thatare within 2.5MH of theproperty line.

Meet or be lower than lightlevels in IESNA RP-33-99.
