[ARC5] BC 453 request - ham radio

[Peter Gottlieb]

Agreed.  I replaced all incandescents with LED lights and did not noticeably 
increase the noise level.  If I stay up late the noise level gets quite decent 
even if I have every light on.  But then again, I tested them.  Find LED bulbs 
on sale and take one home to test.  If it is an RFI emitter, return it.  If 
quiet, buy a pile of them.

I really like the LED bulbs as they are extremely reliable and I can leave the 
place all lit up without having an outsized electric bill.  The early LED bulbs 
didn't live up to their life claims but I haven't had to replace a bulb in at 
least a couple years now while previously I was replacing one or two 
incandescents each month.
