Depending on size i have used a couple of things. For smaller theatres I recommend Chauvet Colorband (i bought the pix version because I also use them as
eye candy). For a 24 ft tall
cyc wall with a row of top and bottom and lights placed end to end they work well. However if you hit them with front light at all they disappear. I have this by using groundrows and higher angle lighting positions to minimize bleed. I once rented colorforce 72's for the bottom of the
cyc for a show and they were so bright they washed out the colorbands that were at the top. Another plus to the colorbands so far is that I have bought them at 3 different points and they blend color wise very well i cannot tell by color output one batch from another. I will say that in the 4 years I have owned them I have 3 units that have died for one reason or another. When buying DJ
level gear be aware that the failure rate will be higher than professional
level gear.
I just demoed an ovation
cyc 1 fc. I loved how they looked in the few minutes I was able to use it. I am planning to buy a few of them but have no real show experience with them yet.
In reality without knowing the size of your
cyc it is hard to recommend anything. I will caution however with any of the tri or quad colored
LED fixtures I have noticed a shortage of Deep colors on the
cyc. No deep green, intense lavender, or deep red. The primary reason I want to upgrade to the Ovation
Cyc Units is that they seem (in the 30 minutes I got to use one) to have deeper colored chips and deliver a much better field of light.
All of this being said, if you are able to demo units you will have a much better idea of how they perform in your space. If at all possible I would recommend this.
