They could just be led bulbs in a standard 120v socket also... in those
there is a switching supply in the base of each bulb.

Subject: [RFI] LED lighting
Well after a 4 year period the local electric company found the offending
lightning arrester and voila no more noise! Unfortunately, the neighbor
behind me just remodeled the outside of their house and in the process added
about 6 LED lighting fixtures in the soffit across the front and after a few
days of watching and listening it appears that they are causing way more RFI
then the faulty arrester ever did.
I am hoping to learn a little more here before approaching them to make sure
all my facts are straight. I am assuming that there is a switching power
supply running the lights and that the power is cut to the supply when they
are not on since the noise is gone when they are off. Is it possible to try
and suppress the noise on the leads coming out of the power supply? Does he
need to contact the manufacturer to replace the supply? Unfortunately they
are mounted into the soffit like a can type light you would have inside your
house and I hope the power supply is accessible.
Thanks
Phil
