Hmm. Well alot of the articles on the Opti 30 RGB are saying that is flicker free.
"In addition to its compact size, the Opti 30 RGB features a number of new upgrades that make it the ultimate advanced color-changing fixture. One of these is new LED driver technology, which gives it flicker-free operation, making it ideal for TV and video applications."
