I've been listening to a weak FM radio station, on a radio, and 2 feet
away was a desk lamp. It used a CFL and I noticed static or some kind
of interference in the reception. It could be lessened by changing the
frequency a little, but the result was still less volume than when the
light was off.

So I figured, LEDs! They won't make interference. Bought Ecosmart.
Then the radio hummed so loud I couldn't hear the station at all.

I will probably go back to incandescent. Any other way to get rid of
the hum?


Probably expensive but if the lievertising is to be believed, these might fix your problem.

It's $19/2 of them, at Home Depot and Amazon, and Amazon has one for
almost $10. Thanks. Expensive but a good idea.

Bob, there's one other bulb in the package. I'll try that

As I said, with the CFL the interference could be lessened by turing the
radio off frequency a little**, but with the first LED bulb, I turned
the tuning knob a half turn in each direction, from maybe 88 to 92 MHz
FM. and the hum was the same everywhere, twice as loud as the sound had
been. It's interesting that it interfered with FM reception, which is
less vulnerable than AM, but it appeears, not invulnerable.

**An advantage to analog tuning over digital tuning.
