[RFI] LED ceiling lights

[EDWARDS, EDDIE J]

Pete, 

Couple years ago had a kitchen remodeled where they installed "Lithonia Lighting LED Round Ultra-Thin Wafer - Switchable White" 6inch diameter LED lights replacing RF quiet old-style fluorescents.  They were model WF6 LED 30K40K50K 90CRI MW M6.  They come in WF4, WF6 and WF8 sizes.  

The "wafer" mount LEDs themselves were not the source of RFI, but the "Remote Driver Box", as they called it, screamed with RFI on HF especially around 10 MHz probably due to power wiring lengths to the kitchen.  I would have tried to pull one out with the driver box to try ferrites, but discovered doing so would probably damage the drywall ceiling.  Besides that, they were not what I asked for to begin with. 

I had originally asked for a light with the option to replace LED bulbs with incandescent.  These were not that option.  In fact, you'll tear up your ceiling or worse when it comes time to replace the burned out wafer style lights which is what happened during their replacement with standard light cans for the flood light style GE LED bulbs I am using now that very quiet more than 12 inches away.  

Put in the standard can for incandescent or LED ceiling bulbs.  You'll be glad you did.

Subject: [RFI] LED ceiling lights

I'm launching into a basement remodeling, getting rid of a suspended ceiling with old-style fluorescents.  I had previously replaced a number of the tubes with LED units, and did not notice any increase in my noise floor with lights on.  I'm now contemplating a wallboard ceiling with a number (maybe a dozen) small  (~6 inch) LED lights.  Has anyone had specific experience with these and can recommend (or recommend against) specific models from an RFI perspective.
