KentCurtis;32852 said:I had this exact question, Tom. I have seen everyone advocating the T5's around here, much to my dismay after setting up my 55 watt PC bulb with an AHSupply reflector on my 20g. Would you think it be more beneficial for me to run a 2x 24 watt setup, like a nova extreme fixture, rather than my current 1x 55 watt? From what I have been told here 55 watts is a fair amount of light and I may benefit from knocking it down a notch or two, so the 48 watts may be a good thing for me.
