I have 8 of the 64 LED Pro lights in 2 Arriba cases. It doesn't fit with them mounted on a T-bar, so that's my only complaint. so much for saving set-up/tear down time. But it does work.
Standard Par64 cases would not work, the lights are not as deep.
Similarly, I have 4 of the same cases, each with a T-bar and 8 Par38's on it(top/bottom). Fits tight but fights fine and no problem zipping it closed.
