I believe that a S4 with a
Seachanger exceeds the weight capacity of a
Right Arm (It's at least is too close for my comfort). The
Seachanger adds a lot of length to a S4, meaning it's probably too long of a
fixture to be able to give you much if any tilt when positioned in a
Right Arm. Finally, perfect balance of a
fixture is critical for a
Right Arm's proper operation, trying to get a
Seachanger perfect would be VERY difficult due to the length and weight. I had Seachangers and Right Arms at my old theater and always went with an
I-cue instead if I needed a
Seachanger to move, it was just easier.
Note: Right Arms are awesome and I generally prefer them to I-cues, so don't take this as any sort of bad mouthing of that product. I just wouldn't use one with a S4/
Seachanger.
I agree with Esoteric, I wouldn't buy an
LED ERS for a few years. The price is going to be way too high to make them at all
practical for a while, and the outputs were a little low. I haven't seen the
LED S4 in person, but I did see the Strong Neeva and the Prisim
RevEAL at
LDI 2010. Both were very cool but the output was not high enough and the price was way too high to consider.
