I have some Color Force 72s and 12s picked up used and have found the bottom of their dimming gets very steppy with slow timing. Wondering if there's really something wrong or if this is normal behavior for them. Used as a ground row, they're so bright that sometimes they'll be in a cue at 10-15%. Use a 6+ second fade up from zero on that cue and the steps are very noticeable - makes them unusable to me. We got through a couple of shows without noticing it since at higher intensities the problem is masked/nonexistent. You have to be fading at a rate of maybe less than about 3-5% per second while crossing below 12% intensity to really see it. A variety of different modes and data runs including direct to our Ion doesn't change things.
