Agreed, your lights will not be too much just pay attention to acclimation and positioning when you move them over. What lighting do you currently have on them?
As far as bulbs go, I don't think you can go wrong with ATI, bulb choice is really up to you as far as color goes, but with 8 bulbs you have a ton of choice. If it were me, I would probably run 3 ATI blue+, 3 ATI aquablue speciels, 1 KZ or Ati pink/purple bulb and 1 GE 6500k bulb but that is just my preference (might be too blue for some).
