if i understand correctly, that you are choosing new pc bulbs, i would check out the UVL PC-R bulbs. they have internal reflectors that make them a bit better, and they come in some nice color temps, not just 10k and actinic like the current bulbs. reefgeek carries them if you can't find them anywhere else.
