3 and stop, I have wooden blinds on the windows and doors so they block most of the light. It is not black but it is relatively dark. I solved the pupil problem by having hanging lights and a reostat for the ceiling fixtures away from the table. There are small lights (on resostats) next to the couch and a hanging light over the bar. These provide enough light for the eyes to adjust (and make a drink) but leave the rest of the room reasonably dark. When I made the room I wanted it relatively dark around the outside of the room but not pitch black. The double french doors that lead to the kitchen cast a kind of glow during the day and this helps too. I wanted (and got) the pool room effect without being in a dungeon. It just takes some time and thought. I think I have more of a night club effect with enough lights in specific place to have the room appear to be darker than it is.
Don't know what to say about the shorter light except that you could probably get a four footer and a two footer to place inside. If you are on an 8 foot table that might work. I find that an 8 foot light is necessary for even lighting on a nine foot light.
The color corrected lights are the best way to go. If you read about them you will learn that they are easier on the eyes. I am 65 this year and often play for 5 - 6 hours. I doubt that I could do that with weaker or un-corrected lights. When I play in the league on seven foot tables I find that after an hour or so my eyes are tired and that I have a more difficult time seeing the balls in many of the taverns where we play. Good lighting is important to me.
In my thinking the lighting is more important than what they look like. I have spent a considerable amount of time building and using my room. I have a particular style that I want and the lights have to be right and meet this style.
OH, BTW one of the things I really like is the use of duct tape to hide the sides of the light. There is less glare to the sides of the table but what could make it more of a man's room than duct tape on the lights! Of course I used classey looking black tape.
