Can Light... What kind of Bulbs?

I am looking to replace the bulbs in the recessed or can lights on our main floor. The space is about 36' X 17' (Kitchend, Dining , and Living Rooms). We have 7 recessed lights and one hanging light above the dining table. The recessed lights have 65 Watt bulbs in them.

What I'd like to know is what kind of bulbs should I put in to get the most light out of them. In other words we would like to make the room a little brighter. Since this is slickdeals we'd like to get a "slickdeal" on them but am more concerned about getting more light.

Thanks in advance for any help!
