I've installed a two HO T5 bulbs using an Advance ICN4P32SC electronic ballast. The ballast is very similar to a Workhorse 7 ballast. It is not made to run T5s, but it seems to be doing very well. Since it is a instant start and not a program start ballast, I don't think the bulbs will last as long. Probably only 1 to 1.5 years. It is the same wiring as ODNO T8s. Has anyone ever tried this before?
