[Elecraft] LED Lamps and HF RFI?

[Dauer, Edward]

Had an electrician at the operating QTH today to discuss replacing the
recessed ³can² lighting throughout the house.  He suggested replacing the
incandescent cans (now 65 watts per bulb) with LED lamps (same lumens with
10-13 watts per bulb).  I have looked at the Internet on the question of
RFI from LED bulbs and see wildly inconsistent reports.  It is the case
that HF radios like the K3 have LEDs in their panels; but I would be
installing as many as 60 LED fixtures running at 10-13 watts each.  My
caution comes from my novice days in the 50s when a single fluorescent
lamp put my hamming out of business - things were quiet when the only
light source was the filament of a 6146 and the dial lamps on the HQ-100.
I know that LEDs aren¹t at all the same; but I don¹t want to relamp the
house if it puts me off the air.  And if they (or their power supplies) do
generate RFI in the HF bands, would the K3¹s NR get rid of it?  Anyone
have any good data on this?

Tnx,
