growing with T5s

during veg full spectrum has given nice results but i was wondering if I should continue full spec. in flowering or go all red.

also my set up is to areas with four fixtures that are 4 bulbs 4'x1'
in each area I have one hanging above the plants and one fixture mounted to the wall as to give the undergrowth a dose of light. each fixture is 20,000 lumens. Is this an efficient set up or should I hang the fixtures all from above the plants?

Also, is there any difference in the efficiency of the big CFL bulbs that use the mogul socket and the linear T5s other than how they cover square footage. I mean is one better tham the other?
