To those that were not impressed with the output of the T5 they've seen, do you know what fixture it was?
I have been following the massive T5 thread on RC... somthing like 150 pages... and the consensus there is that T5ho without good reflectors is about the same as PC, but T5ho with good individual reflectors (like sunlight supply or icecap) is stronger than halide. Infact, there are instructions for how to acclimate your tank when you switch from halide to T5ho so that your corals aren't burnt.
For example, I have been told that the 96w Tek fixture over a 30gal tank might be too intense for some softies, but even a 175w halide wasn't too much light over my 20gal. And a more recent post claims that halide drops off quicker as it gets closer to the bottom???
I know that most of what we read on bulletin boards is just recycled quotes from somewhere else eg, how many times have you heard "wet/dry filters are nitrate factories" or "refugiums need lower flow" etc.
I am just trying to make sence of the difference between the majority of what I read about T5ho and some of the members' experience in this thread...
could it be due to the reflectors? Or are all the RC posts just over-hyping T5?
Thanks,

- Chad

ps - I should add that in the same thread, it was reported that halides with a new kind of "luminarc reflector" are brighter than the Tek T5ho.
