@bwmalloy do you have any thoughts (now or later)? Not sure where in FL we are yet on this one. Miami?
Lemme say I'm a halide fan and I have nothing against T5's. It doesn't take any time on a google images search or R2R thread-search to find examples of awesome tanks lit by each kind as well as combo's.
That said, if you'll have to use a chiller, I would really, really consider going 100% LED on lighting. The cost numbers are already heavily in favor of LED's, but if you tack on chiller expenses the costs are a little c r a z y.
You can buy or build an LED system that will give you the same spread, punch, sparkle, pow, bam, shimmer, thwack and pop as the hybrid you're planning

....but more importantly perhaps, it will keep you from running a chiller...at least very much.
If any of that seems to make sense for your situation and you're interested in some other hypothetical ideas for lighting, can you tell me what budget you had in mind for your lighting system?
Just for perspective, have you had any reef lights in the past that you've loved or hated? Or other peoples tanks you could link to that you love or hate their light?
