AH Supply T5HO

Hello All,

What a great thread. I have a question concerning the AH Supply T5HO Bright Lights they sell with their reflectors. On Hoppy's chart he refers to their PC fixtures and reflectors and PAR readings but no mention of their T5HO lights. I'm sure Hoppy has better things to do than test every fixture on the I have 2 48" T5HO of those lights w/reflectors over a 90 gallon about 24" above the substrate and about 8" apart. I am looking for the high end of medium light. I use CO2, I just do not want to go crazy with it as I use Excel. Is this enough light or not? Are these lights on par with Catalina's line?
