a 3 lamp is for 7' tables..... 8 and 9 foot tables should have 4 lamp,i have 12ft ceilings in my poolroom the lights are at least 4 ft off the table.i use flourscent lighting in my house for 90 percent of the lighting....these 4 lights over my 9ft.table are old style with the brass piping and the green crystal shades are glass with a 1910 style to it.i wanted them to hang taller off the table more than normal so a person wouldn't hit their cues on them..i also installed flourscent screw in spiral look bulbs...they are called 150 wt of light they put out but use about 40 wats of electric...these 4 bulbs putting out 400 watts of electricity is all my room needs for good lighting,,everyone that comes over raves about the good lighting...in my opinion these so called recommendations to have the table light about 31 inches or so off the table are too low..also for best selection for all watts on flourscent bulbs go to Menards they have 200 and 300 watt screw in now.. guod with your projuct n
