A 2' pc fixture can be rated at lets say 2 x 65w.
A 2' T-5 HO fixture can be rated at 2 x 24w.
I know lumens mean everything, but on alot of Forums you hear people say you need X amount of wattage per gal.
Now if thats true would you not be better off going with the higher wattage bulbs?
Now iam going to stand back and put on my flame suit ( so I dont get burned )

Lumens is important, but par is more so.
very simply put, par is the ability of any given light source to penetrate the depths of your tank.
Higher wattage does not always mean higher par.
if you do a search under "halides" you will find some very good articles and discusiion on this....
