[RFI] LED lighting

[Phil Snyder]

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
