Couple things to know that are not published.

Wait 5 minutes between any switching so the ballast resets itself.
Bulb apparently burns significantly brighter if run on 220V and ballast is more efficient .... I don't see how, but, that is what I was told. Either way you bring in 220v and it gets split to 110.

Going to run it for now on 110 until I can wire up for 220, time for subpanel.
