For those looking at CFLs or LEDs in the shack, and presuming that is where you

the cheapest things I own — after all, I have a full
On that subject, does anyone know of any tests for which brands of lamps (LED,
I don't use CFLs!) are better for low EMI? As noted it would seem that the
name brand units would be better in this regard, but maybe not?
