Wondering which would be better for a 3x3x2 cab.. either two of the small 150 hps or maybe a cool tube 250? or would that be to much heat maybe? I have one 4" tjerlund fan on a carbon scrubber

or, would maybe one 15ow hPs in the center at top and then 1 or 2 55w on each side of fixture at top


I just dont want to waste any money and not be any better, or maybe have to completely change everything to get somehting else to work.

Ive been searching all different light options, including LED and still havent seen anything conclusive on those and penetration.
