After looking over the methods used by others here, I was unhappy with the choices available. Either the bulbs were too expensive, or not good size-wise.
Ultimately, I decided upon the following: Phillips F72 T12 6' 85watt HO 6500K bulbs. This will allow for coverage w/o overlap or underlap.
BTW, I am vacillating over which ballast to use. There are the good ol' fashioned type, and the electronic a la Fulham. The latter appears more expensive. But is it worth it??
