- Proper orientations, locations, illuminances and controls that satisfy needs for any type of contingency
- Number of poles based on the width of the sideline
- Quality of cutoff or spill light control

LIGHTING OVERVIEW
- Horizontal
illuminance a measure of the lumens per unit area on a horizontal
surface. Normally it is measured three feet above the playing surface.
- Uniformity
illuminance a measure of the rate of change of illuminance expressed
as a ratio between the illuminance level of adjacent measuring points on
a uniform grid. The limit of uniformity varies with the speed of the
ball.
- LUX
a measure of illuminance weighted to the spectral sensitivity of the
human eye. It is defined as 1 lux = 1 lumen/square meter.
- FC
foot-candle. The official definition is 1 foot-candle = 10.764 lux;
however, it is easiest to approximate at 1 foot-candle 10 lux.
