yes, I believe it may be limited to cheap chinese ballasts, lol
Its not necessarily the "cheap chinese ballasts" because the truth is that all the companies are made just about the same, most likely assembled from the same little Chinese child. The problem is that there is some kind of a broken coaxial coating on one of the cables. That is what is picking up the high levels of frequency (hertz levels) that the ballast is throwing off.
You need to shorten the length of the lamp cord, it is acting as the antenna for the RF, or fix the broken coating on the cables in your house. This is why Gavitas have become so popular, is because they eliminated the lamp cord by mounting it on the reflector. Hope this helps! -Cheif
