I am thinking now that going with the (2) 2' units, then I could be more flexible in the long run, I also have a 24" ,18" and 12" from old tanks that run T8's that I could use to mess with the feel of the light. I can't stand the yellow light myself. I hear you with experimentation but don't want to end up with a pile of bulbs either!
Thanks for your time!
