best for veg is GE daylight bulbs (veg spec is 6500k)

best for flower is kitchen and bath (flower spec is 2700k)

daylight bulbs are 3050lumens per 48'' bulb. kitch and bath are only 1600 so you may want t add another double fixture when it is time to flower.

also consider cfl's. they take up less space as the don't need a special fixture.

hope this helps.
