None of the above... I have the new Solaris LED fixture. Started out with it (no point in wasting money on intermediate fixtures, I knew I'd want to upgrade), but haven't progressed to the more demanding corals yet... that will come with time. The tank is only six months old.

I use Power Compacts (2x96W+2 LED Moonlights) over my 20" tall 55G tank. All softies and LPS right now, so it seems ok.

What I don't like about it is...well, obviously it limits me as to what I can keep. And the bulbs are hella expensive if you buy them from the LFS. So, instead of spending $100 on a MH bulb every year, I'm spending $160 on PC bulbs.

Obviously, aesthetics play a huge part in why and how we keep our aquariums. Power Compacts aren't, in my opinion, as aesthetically pleasing as either MH or T5 (I've never seen the Solaris in action).

What kind of lighting are you using?
 

I'm using 6 48" HO T5's. Four 10,000K, and two Actinic. I plan on adding a 150 watt Metal Halide (which I have) soon. The lights are all on timers to come on in sequence to simulate sunrise to sunset.

-i'm using 2x70-watt metal halides, 20 k's so already quite blue without any actinics, but want to upgrade to one 250-watt hqi in the next year, but with my current lighting i can have softies,lps, and sps, clams and anemones so i'm quite impressed with their penetration..

I am using PFO Solaris H4 LED`
 

I am using PFO Solaris H4 LED. It does not appear to be on your list of available lights.
