Everything adjusted and improved considerably over the T5s. I think I would have used a wider variety of bulds, mixing WW, NW, CW instead of just the CW I have now, and I would have probably added a couple of the UV into the mix to try and get better color mix.

I picked up my heatsinks at Heatsinkusa.com, but as rrasco mentioned Rapid has some as well that seem to be priced reasonably.
