[Elecraft] LED Lamps and HF RFI?

[Brian Hunt]

I have a dozen LED lights around the house from off the shelf at Costco. When I brought the first batch home, I fired them and sniffed them with a 2m HT and a Grundig SWL portable. I found no RFI even a foot from the bulbs. 

Look at the contractor's design. If each bulb has its own AC-DC converter it's likely OK. If there's a common supply serving several bulbs then the distribution wires may act like an antenna and cause problems. You could also ask the contractor to loan you a sample and run your own tests.
