Just did two events this weekend with the quad phase and it worked great and was bright enough--awsome light. However, my two color scans weren't used due to the fact that once I placed them on the botton truss they would tilt downward eventhough I had tightened them as tight as possible. To correct this I'm going to have to move some lights around so I can place them on the top truss bar so if they do tilt downward the bars between the top and bottom truss will stop them from tilting further.
If your scanners are like mine I have the same problem... so what I did was used O-Clamps and clampted them to the Truss Stand itself instead of the truss...the stand gives my ADJ HP250 Scanners support so they don't tilt down...
