My school is looking at getting some moving lights, and the ETC Source Four Revolution was one that I saw that looked good. So, two questions. One, are these lights good quality? Most of our lighting equipment is by ETC, and it is all good quality, so I would assume that the Revolutions are the same. Two, we have an ETC Express light board. Can we use the moving lights feature on it to control the Revolutions (I would assume yes, but I thought I should check). Thank you!
