My current waveline DC5000 is super quite and works like a champ the only reason I am going to upgrade it is because it just doesn't put out enough flow.
I am running the DC5000 on my 90 with 2 returns that or both split and it is just barely cutting it at full power I would recommend the DC12000 because that is what I am going to upgrade to.
I have a LED light that might work for you then. it is a 12x3watt CREE fixture with hanging kit. Let me know if you would like me to bring it over so you can take a look at it.
That is not bad but this is what I am looking at for my office....

I have both bio-cube and JBJ running and I like them both but unless you plan on getting the LED retro kit I would go with the Nuvo that is what I am looking at getting for my office.
