I saw in another thread couple days ago that "Fullham racehorse ballasts are the higher end version of the workhorse ballasts and have programmed start/end of life protection and can run 1 or 2 bulbs each."
Try contact this guys and ask the right ballast for you... https://www.lightingsupply.com
Hope other would be able to give more specific instructions and tips about t5 ballasts here.
I run ATI fixtures and their ballasts come with the fixture.
They are very liable, but I believe they need the cooling from the fixture.
Good luck!

Avoid workhorse ballasts and get true T5HO ballasts. A simple trip to Home Depot will get what you need. You want Centium or HEP ballasts. Plenty of online stores carry them as well
I went to home depot and I found 2 Phillips for 54 watts. Called the 800 on ballast. Rep said the lowest it wouald go is 4 39watts.
I found these online and some other ones. Looking for something cheaper if possible. Bulk reef has the hep. There about the same price I think. http://www.ballastshop.com/b228punv-n.html
