ReefGeek put these together for me a little less then 2 years ago using ATI Powermodule dimmable ballasts. They dim with a 0-10v input or run at 100% with no input at all. Endcaps and wiring are perfect with a molex style plug. The reflectors aren't, one set could be polished up and be just fine, the other needs to be really polished or replaced, they're are some larger spot of corrosion on the second set. I'm looking for $65 each set, paypal only.
The can also fire a few different size bulbs if you look at the ballast pic.
