Here's my DIY LED build complete with controller. A bit more than just a LED fixture but I'm extremely happy with it, been running for over a year now without me even looking at it. If you're going DIY, let me know as I have a TON of extra bits and pieces, parts, drivers etc.

I also was probably even more interested in the road to the finished product than the product itself. I'm big on DIY and not everybody understands the joy a true DIY'er gets when it's done.
