General question for the group. I have recently purchased several different types of fluorescent replacements for incandescent bulbs. These would all appear to have electronic ballasts, because of size. They claim to meet FCC part 18, but there are disclaimers about moving the things if they cause rfi in the AM band. Well, they cause terrible rfi in the AM band, and in many cases they cannot be moved, because the radiation arises not just from the bulb itself, but from the power wiring. Just a few bulbs pollute a large home. And by pollution I don't just mean CE, but also RE from the power wires, so it isn't just a matter of plugging into a different branch. What is going on here? What is the point of enforcing conducted emissions on a power supply when lamps are allowed to emit? I understand that the cost of a filter compared to that of a power supply is a small fraction compared to the cost of a filter relative to one of these bulbs ($5- $10) but on the other hand these bulbs dissipate 5-15 Watts - it ought to be easier to filter these than a 200 Watt power supply.
