I have used the HES version, called a Color Merge. It's an older product, and it doesn't have an amber filter, which I think the
SeaChanger does. It's a
bit slow in transitioning between colors, but that's really a minor inconvenience. I do like the color saturation of the HES.
Never used or seen a
seachanger in person.
I second every part of this. the Color Merge was great to work with, nice saturated colors, speed, eh, but slow changes are gorgeous.
Why are we using scrollers. Cost mainly. Also, there are times that a designer decides that he wants R17 and GOSH DARN IT HE WANTS R17. Scrollers are nice because you can put the
gel color you want in, and thats the color. As opposed with
RGB or even RGBA
system trying to color mix the color out (which is usually near impossible).
In the same light (pardon the pun) lets say I have scrollers in my side-light position for a show. I can only fit 3 fixtures on this side-light
boom. I want to be able to match perfectly the colors in all three of my top light systems. With the
SeaChanger or anything simmilar, this would be harder.
However, I think mostly its cost. I'd love to spec a full rig of VL3500s, but sadly I doubt any
producer would let me. Money talks.
