Please use at least 500 lux, as below that it is very hard for OF's to see that little black round thing.
From the World Squash Federation Specifications:-
11. LIGHTING
Lighting Installation
11.1 The court shall be lit by artificial light. The level of illumination measured 1000 mm
above the finished floor shall be:-
11.1.1 Recommended standard 500 lux
11.1.2 Minimum standard 300 lux
11.1.3 TV standard 1200 lux
11.2 The walls of the court shall be lit in such a way as to appear evenly and uniformly
illuminated and the lux levels shall not vary at any point by more than 15% from the
average level of illumination.
11.3 The lighting shall be shadow-free and free from any stroboscopic effects

The major problem is I have a drawing of the court but the auditorium area for the spectators, I have no idea. Also suggest the type of lighting in viewers area and lux recommendation.
Transparent Back Walls
11.4 In courts with transparent walls, the level of illumination shall be the same on both sides of the wall.
From the same Google search as the previous post - you could do this yourself you know. (I love the game, which is the only reason I am doing this).
In other words the spectator area lighting level is the same as the court if you have a transparent back wall. If not then make it safe for them to walk in and out or read the programme or whatever.
