Title: Household LED Lamps cause RFI on shortwave
Post by: AB1BE on April 09, 2012, 09:57:32 AM

From YCCC, here's an excellent video by the German Amateur Radio Club (DARC) about RFI from the new LED lamps (aka LED 'Light bulbs').

Check it out around 11:30 mins.  Whole thing is excellent.

Makes you think twice about using LED residential lamps. Perhaps food for thought for some ML experiments.  :)

Thanks Ken,

Very interesting, I posted a video response (to be approved) to his video.

Cheers,
Martin.

Here is the ballast output for a common electronic ballast. Not terribly clean RF wise, and as it is SELV there will not likely be any RF shielding used on the wiring.
