How high should your pool table light be above the table?
The bed and rails of the table must receive at least 520 lux (48 footcandles) of light at every point. A screen or reflector configuration is advised so that the center of the table does not receive noticeably more lighting than the rails and the corners of the table. If the light fixture above the table may be moved aside (referee), the minimum height of the fixture should be no lower than 40 inches [1.016 m] above the bed of the table. If the light fixture above the table is non-movable, the fixture should be no lower than 65 inches[1.65 m] above the bed of the table. The intensity of any directed light on the players at the table should not be blinding. Blinding light starts at 5000 lux (465 footcandles) direct view. The rest of the venue (bleachers, etc.) should receive at least 50 lux (5 footcandles) of light.
