The egg-crate diffusers make a significant difference. There is a room I go to in Atl that has an older style wood light that has been retrofitted with qty 2 2x4 LED panels over each table. The diffuser is the one built into the panel (none extra added). It lights the table fine, but is slightly uncomfortable when walking around the room.
The Littman light (which has an external parabolic chrome egg-crate diffuser), even if you are looking directly at the light from the side, is comfortable to the eyes.
The absolute worst light in this respect is the Arena lights. They are nearly blinding from the side, the most uncomfortable pool hall experience I've ever had. Alsmot as bad are the Perimeter lights.
