Hey chief, I think this is primarily a problem when taking pictures too close to the older magnetic style ballasts, which emits a magnetic field. I've seen some posters post growroom pics and this was obviously an issue, then they posted other pics away from the growroom and the problem disappeared. I may be wrong, but that's my take on it.
