Lighting

[VikingsGuy]

I am setting up a 16'Wx10'Hx10'D simulator shell (plenty of room to the back - the shell is at the end of a long room) with the Garmin R50 placed 9' from the screen. What type of lighting do I need. Will just ambient from the rest of the room and reflection from the screen be sufficient? If I add light should it be ceiling diffuse lighting? A single top down spotlight? A pair of top down spot lights at opposing angles? If so at what angle? Some type of side lighting?

Thanks for any help/direction!
