Intensity: T5s vs. Power Compacts

I don't use T5's so my opinion is based on reading a lot about others who do use them. It seems that T5's with good reflectors, one per bulb, produce from 30 to 50% more light intensity per watt than PC's with AH Supply quality reflectors. Part of this is the single bulb per reflector, part is the reflectors being somewhat parabolic, so they reflect more of the light from the back and sides of the bulb to the water, and part seems to be that the bulbs are just brighter to start with. I can stare at a PC bulb, but it is difficult to stare at a T5 bulb.
