Family Room Lighting

[ccracin]

I am seeing the end of my basement finishing project. I am to the point that I need to order lights. The room is about 600 ft^2 and has an 8' ceiling. The ceiling is the suspended type with 2'x2' tiles. I am going to use T7 size recessed light fixtures with the flouresent style flood bulbs. Not sure of the number. They are equivalent to a 65watt R30. How many do you think I need and what spacing? I have found alot online and can't make up my mind as there are so many different opinions. Any suggestions would be greatly appreciated. When this room is done I'm hitting the garage to work on the truck.

Thanks,
