Golf simulation projectors need to be brighter than a home theatre projector, since you need enough light in the room for your camera to see your club and track ball spin as it travels to the impact screen. A 3000 ANSI lumen projector is a good starting point for a smaller impact screen, but for larger screens that are 10 feet or wider, you will want to look for a 4000 lumen or brighter laser projector.
