I have 12 Z175 fixtures in our lighting rig. My newer lighting guy ran them at 100% everything. After 5 minutes, they all started flickering the green LED. Never had run into this issue as we have never run them at their full capacity. After some research/troubleshooting (and to make a longer story short), I have concluded that they are overheating as the fan (though it is on auto) is not kicking on. Is there an issue with the light or firmware? There is no fan dmx channel for fixture profile to control it that way either.
