Just bought some LED PAR 20 lamps today and it said about them while not dimmable, and would switch off at a certain level implying either they dim or would work at full but at less than full voltage. But also, not to use them with electronic power supplies / dimmers. Confusing on that note but appairently they would get along better with magnetic. I know dimmable by any means Encapsulite fluorescent stick lights work with either type of control by way of magnetic ballasts by way of working a lot with the fixtures over the years and even using the parts to make some custom fixtures. You can dim say the fluorescent fixtures with a ETC rack without a problem and magnetic ballasts if quality are very simple to do.

On the other hand, electronic ballasts are perhaps more fogiving in not being sure but as opposed to needing full run up, than dimming down - while more perhaps stable the magnetic might be, the electronic ballasts might be more forgiving in startup and dimming minimum levels. Electronic dimmers and electronic ballasts would probably work better with each other than resistance dimmers with electronic ballasts.
