A Picture or more of the noise that I found with Diode Lighting as well as any other thought provoking rfi. As always the thread is open to theorists and other thought expounders who may have solutions or other sources that can be solved by the "best" in the Flexerhood. Here is a couple of starters:

Jim,
I have LED lights for my shack (ceiling).  I haven't noticed any noise from them.  My antenna is about 120' away.

I have a 20,40,80 mtr rotatable dipole at 30 feet here as well as a 160 mtr Windom at 42 feet, the latter is broadside E/W while the Rotatable is usually pretty much N/S, and as such tends to show more noise since "downtown" is to the south about three blocks.

I'll resend the last couple that I sent in another thread about two different lights from the same company that I discovered.  The Bad Light

The Better Light

Interesting - the lower light doesn't have the official UL logo.  

I've always advised buying 1 light, plugging it into  lamp in the shack, and running some tests before committing. If the lamp has a poor quality switcher, it'll throw hash around.  Here is what I have outfitted the house with. Utilitech. It isn't a terribly expensive lamp either, but quiet.  - 73 Mike N3LI -

Upon rotation (180 degrees) of the "lower" light, I found this, so it is actually ul listed hi.
