Could it have been that only one of the new lights was causing the
problem.

I verified that each of the lights by itself was a problem. Bad
manufacturing lot? Who knows? All I know is that they were unacceptably
RFI-polluting. I got rid of them and replaced them with lights that were--
right out of the box-- free of RFI. Problem solved. Hope this saves someone
else the three hours of work it cost me.

There is no way I was going to go back to the store and buy four more of the
bad lights on the basis of "Well, maybe four is too small of a sample size
to draw any conclusions." Fool me once, shame on you; fool me twice, shame
on me.

I reward companies that make RFI-friendly products and punish those that
don't. Always have lived by that dictum. I also try at every turn to educate
my neighbors to the same, so that we can all have as quiet an RF environment
as possible. Hence, my purpose in posting the original post here.
