I am remodeling my basement w/a size of 25 X 15. I installed 6 recessed lights in the room. Right now each has a bulb of 65 watts. I just got them going a few days ago. Also put on a dimmer switch that will come in handy for the movies we will be watching on the big screen (don't tell my wife) TV that I don't have yet. The room is not terribly bright, but seems plenty adequate. Once the white ceiling drywall is up I'm sure it will brighten it up some.
