A squash hall is a little different from other halls because even the walls are playing surfaces where the ball can bounce. Therefore it is important to also consider the illumination and uniformity of the walls in a calculation The luminaires should be positioned at least one metre from the side walls to avoid glare.
The vertical lighting is important because you need to see the ball at different heights and be able to figure out where the ball is going and react quickly.
