Ahh I only inquired about the DIY led
's. It's far too much for my meager mind to get a handle on. LOL You need Mr x for that question I think, he's the lighting guru.
As far as the halides noise and fans, well you just have to get used to it I guess. You need all the fans for cooling so theres no way around it. I have gotten used to my fans on my T5 setup, it sounds like a jet engine, especially when it first fires up. You got the unit new correct? If so I don't think changing out the fans will help.
