Light fixtures shall use a cut-off luminaire that is fully or partially shielded with no light distributed above the horizontal plane of the luminaire.

1. Light Distribution. In no case shall the total lumens emitted for a single site exceed one hundred thousand lumens per acre.
2. Pole Height/Design.
