Wow, I was just loking into this too. What design did you end up using, the outlet/light cover one? What did materials run and how long to fab it up? Everyone I have talked to who is running these setups claims good results, and the process is rooted in long proven science. I am really excited if it pans out long term. Oh, and let's see some pics!
I used a meyers style tubbing setup, I have 12 tubes total in an acrilic housing.
