You guys are killing me...take a day off and come back to this. J/K
Brenden is right on as these are not low light corals. Conventional wisdom is that low-med light corals still require 2-3+ wpg of good light.
As for different information on the web and in print you always need to check more than one source and what is the motivator of the source (i.e. are they trying to sell you something) and then go with the majority opinion.
For all you know I am some wack job that just likes to give advice willy nilly and have no idea what I am talking about. A few years ago you would have been right on when it comes to SW. Then again I would not be offering advice on something I a just learning about myself (hmm hmm, Real FF)
SharkMan, what kind of 45g do you have? If it is the traditional All glass tall you are going to stuggle with some corals due to the depth of that style tank. Not to say it cannot be done, but even if you do get 3+ WPG (ideally 4-6wpg) of lighting realize it will be diminished by the time it gets to the bottom and position corals appropriately.
Eclipse are nice, but not the ideal style lighting/filtration for a SW setup let alone reef. Do you currently have any additional filtration?
What do you ultimately want to do?
