(A)   Any operation or activity producing glare shall be conducted so that direct and indirect illumination from the source of light shall not cause illumination in excess of one-half foot-candle when measured in a residence district and so that it also meets the standards of the American Conference of Industrial Hygienists.
   (B)   Flickering or intense sources of light shall be controlled or shielded so as not to cause a nuisance across lot lines.
   (C)   When street lighting produces illumination in excess of one foot-candle at any point in a residence district, the contribution by light sources from within any of the manufacturing districts measured at the same point shall not exceed 50% of the street lighting.
