LOL....
SushiReef,
believe it or not, neither Scooterman nor myself intended to give you a brain spasm by throwing all that info out there. It was more of a "Here's some useful info, do what you want with it", kinda thing.
Scott is an electrician by trade, I'm a cop who watches electricians work from a safe distance. I'm also one of the guys who studies something to death, playing all the angles out and seeing worst case scenarios before going for it....byproduct of my career choice I guess.
I did alot of reading and calling and dbl checking everything I could before buying my lighting set up. I purchased two Sunlight Supply Bluewave IV ballasts for my tank. The SLS BLuewave IV's are nothing more than IceCap E-ballasts already hard wired and placed in a pretty blue box for the buyer. You pay more for them, but you also get a 5 year warranty instead of the IceCap 3 year warranty...even though its the same ballast inside.
You're really not gonna go wrong with any of the ballast's discussed above, so you'll be fine with whatever you choose. One thing to remember is that with almost all MH bulbs these days, you dont need the Actinic supplementation for anything other than aesthic appeal...
So basically, I'd suggest going to JBNY's site and looking at the pics of his tank with the different bulbs actually being run over the tank, (unless you already have one in mind), pick one or two out that you like the best appearance wise, and then see how it does with the various PAR ratings. That will probably help you figure out which ballast you want to go with.
