For the lights, I bought four Sfiligoi XR6 400 watt MH + 4x26 watt T5s + 4 LED night lights. These are REALLY, REALLY nice lights.
One of them was for the frag tank and three were for the display. Fortunately, I tried one out first. If you buy these, there's something to watch out for. There is pink plastic inside that you need to pull off:
No problem, right? It was a piece of cake; I pulled off the plastic and was done (or so I thought). I then mounted the light (more on that later) and enjoyed finally having the tank lit. After a few days, I noticed there was some melted plastic inside on the reflector:
I did a quick search on Reef Central and google and found several other folks who bought their XR6s this Spring who had a similar problem. It turns out there is a very fine, thin layer of plastic on the diagonal pieces of the reflector that are just barely visible. This is different than the loose plastic that you should obviously pull off. They are on there tight and flush and you have to pick at them with a sharp knife to finally get underneath and pull them off. If you don't (and a lot of people didn't), then you end up with the melted plastic.
Fortunately, I only had tested out one light. After reading about what caused the melted plastic problem, I took the wrapping and loose plastic off of a second light to see if I had the plastic on there and upon very close examination I could see it. Here's a picture with the plastic still on the 4 corner pieces of the reflector:
It is so thin, you can hardly see it. And, it's still quite reflective even with the plastic on there, so it's easily missed.
I called up the West Coast rep and a new reflector is $150 and the corner pieces are a bit less. Lesson learned. I don't know if those pieces were left on there by the factory just in the Spring or if this is an ongoing issue. In any case, if you buy one of these, don't make the same mistake I did.
The lights come with a really cool system for hanging them. They are suspended by two 1/32" wires that come with some mechanical gismo which lets you easily adjust the length of the wire. I plagiarized some great ideas I saw here on RC and mounted these to some Johnson pocket door wheels which then slide in their tracks. This allows me to easily slide the lights back and forth for exact placement or to get them out of the way should I need greater access to a given area.
Here is the Johnson track door system
I ordered them from:

The thread that I got the idea from is at:

So far so good. Where I screwed up was in attaching the Sfiligoi mount to the wheel assembly. Warning: DO NOT COPY THIS IDEA, IT IS FLAWED.
I found plastic pipe brackets at the local hardware store. These were perfect. They gave me plenty of room to attach the light assembly with a bolt and they had holes that allowed them to be easily bolted to the wheels. Again, DO NOT DO THIS YOURSELF. I'M GOING TO DESCRIBE THE FAILURE LATER ON IN THE THREAD.
Everything was fine and I was really happy with the assembly. The lights moved back and forth easily and it looked good too.
Here is with the lights close together:
And this shows how they can easily be slid over to make room for aquascaping:
