When your camera began to freak out -
1. Were you using a battery or mains power adaptor?
2. Is your HMI lamp powered by a magnetic ballast or electronic ballast?
2. If you were using mains power and your HMI lamp's ballast is an electronic ballast, was your HMI light running on the mains power or a separate generator?
3. If your camera was running on battery, were you operating your camera anywhere near the HMI lamp's electronic ballast or lamphouse cable?
With the answers provided, some people wise on the topic of discharge lamps, switchmode power supplies, their effect on the 50Hz mains power waveform, the neutral line voltage/current and RF interference in general may be able to advise more validly than I.
A few years back, my P+S Technik/SI2K, already running off mains power weirded out when a 12K HMI with electronic ballast was switched on. I had to use a camera battery to make the issue go away.
