[Elecraft] Noise from LEDs

[Ron D'Eau Claire]

Yeah, Jim said he had actual smoke damage from his going up in flames and used a fire extinguisher. Guess I've been lucky over the years. 

After finding some brands of CFLs that are don't generate hash across the HF spectrum, I am just starting to experiment with LED replacements as the CFLs die. 

One trait of the CFLs that I miss in the LEDs is that CFLs take several seconds to come up to full brilliance. I found that much less jarring on the eyes, especially in a darkened room.

Ron,

I have had two CFL’s fail that were well beyond a “puff of smoke”. Both were actually melted and charred black. They were from two different manufacturers. I also have had CFL’s simply quit after a few years, and the base of them was brown from overheating.

That is part of the reason why I converted all bulbs in my house to LED.
