How does a source 4 junior compare to a regular S4? a 360Q? We're looking into buying a few new lights at my school and before I make my recomendations I wanted to see what people with more experience with the different fixtures think. I know that 360Q's are very affordable used, but finding used S4's wouldn't be bad either. Currently all of the ER's we're using are 360Q's. I really don't have any specific questions compmarison wise, just seeking any information people have.
