Since you gentlemen and ladies in the business have access to some of the manufacturers, have you ever tried to get an answer from one of their design engineers? I know it may be impossible to get through the phone system but one would think the design engineers would know exactly what's happening or what problems they have encountered in their tests. And hopefully they may have some solutions.
I know I have struggled with the poltergeists of fluorescent lighting and would love to better understand its idiosyncrasies.
