I work at a pool hall. We have the Littman light and the old diamond lights with the 8 8 ft t8 lights and diffusers in a box. And 2 perimeter lights. They all work very well. The perimeter light is 5-10% better tho and does provide the best lighting. Virtually no shadows not even under the rails. I made my own version at home for $300. Basically it’s just 2 8 ft lights that look like the perimeter light with no end cross lights. Works 90% as well.
