and
The site illumination model allows a maximum grid spacing of 10 ft. x 10 ft.
All lighting is included in the model, including emergency lighting
The calculation grid is based on the zone.
For school sports fields the measurements are taken twice - once with the lights on, and once
with the lights off. With the lights off the measurements must be less than or equal to those of the
given zone. With the lights on the measurements must be no greater than those listed on pg. 137.
