Fair enough, I can see why you would install them live. We predominantly use Tridonic T8 Top and I haven't had serious problems with them. Now here is an interesting one. We use T5 UV tubes in one of our products. The Tridonic T5 Pro doesn't seem to be powerful enough to keep them going. Another thing we found was if you have lots of T5 Pros in a circuit strange things happen. Some of them refuse to start. The T5 UV tubes are quite happy with T8 Tops though.
