It would be QRN, not QRM. Anyway, I have tried 2 LED lamps and they both wiped
out FM completely and messed up AM. The expensive Sylvania was worse than the
WalMart Great Value. CFL lamps bad, but not as bad. CFL lamps....last longest
burned base DOWN. CFL lamps being instant start do VERY poorly with frequent
switching. Same as HF based linear fluorescents as well as magnetic instant
start. Put them in an inclosed fixture and life will be substantially shorter.
I expect LED lamps in an inclosed fixture will also have a reduced life
expectancy as in an inclosed fixture there is heat. Heck, I found incandescent
lamps in an inclosed fixture had a reduced life.
My bedside radios now have incandescent lamps close in to read by. I just
can't find a high enough lumen lamp for reading...... halogens get too hot. The
ones that rate the same as 60 watts are not bright enough.
