I strongly agree, Ed. I first encountered this in the home that we
bought in California in 2006. It has several low voltage lighting
fixtures, all run with what the electrical supply houses call
"electronic transformers." They are unbranded and unlabeled, and they
are noisy switching power supplies.
These little boxes are, for all practical purposes, the only way to
power these devices because a real transformer is four times the size of
the electrical back box into which it must fit. If any clean supplies
exist, I sure would like to know about them.
