[RFI] RFI from LED Snap-In Modules

[Jim McCook]

New construction in California does not allow screw-in sockets for 
ceiling lighting, so the usual case is to place cans that receive 
snap-in LED units with self contained switching power supplies.  I have 
had severe problems from these units from a new Shea Homes development 
over 1000 feet away.  Now my next door neighbor has rebuilt from the 
ground up and has already placed ceiling cans for the snap-in units, 
despite my request for a discussion on lighting months ago.  We have now 
discussed the RFI issue and the fact that RFI, should it occur, will 
have to be eliminated.

I am not aware of any snap-in LED modules that have built in analog 
(magnetic transformer) supplies, which would be ideal.  Is anyone out 
there aware of a specific manufacturer who provides these units with 
proper filtering and shielding that effectively eliminates RFI?  There 
must be some good ones out there somewhere.  If not, the owner is faced 
with replacing all the cans with screw in sockets for LED floodlights 
AFTER final inspection. He is aware of FCC rules Part 15 and 18 that 
prevent interference to hams.

Please let me know if you are aware of specific manufacturers who supply 
the proper snap-in units for ceiling lighting.   73, Jim W6YA
