Ok first off I gotta say what a great product this is.  I haven't purchased one yet but I really like the capabilities of it.  I've been researching the Profilux II on CanReef and also on other forums.  I still got a few questions, and I am still making a wish list of all the components I want to attach to the unit (e.g. tunze(s), LED(s), and whatnot).  
My first question would be associated to the dimmable ballast option....more specifically dimming a t5 ballast.  I have been reading as many websites as I can but haven't seen a whole lot of ballasts on the aquarium vendor sites that sell dimmable ballasts.  A few pages back I found the link to the Sylvania ballast, the Sylvania 49673 QT2x54/120 PHO-DIM.  I was just seeing what other brands there are that would run t5 high output lights that have the dimming option?  I figured out how the unit works, but I'm sure there is more than 1 vendor that makes a ballast like that.  
Also, does the circuit board that controlls the dimmable ballast come with a Profilux II?  Or is it a accessory option that must be purchased seperatly?  If so how much would that cost?
I guess it would help to say I'm located in the US.  
 
Any help would be appreciated.  I'm still making a shopping list of Profilux components I want and I'll post them here later to see how I would need to hook them up to the controller.
