I've got a cabin WAY up north. No internet, no tv, no FM, just AM radio and the heavens.
The AM stations are pretty weak, but they'll do. We recently installed some CFL bulbs. We have to turn them off to listen to the AM radio. They cause a lot of interference.
Before I drop max bucks on an LED, anyone know if the generate this kind of noise?

Some do, some don't.
The key is to get the radio antenna as far away from the noise source as
possible, unless the noise is coming in on the radio power cord.
Obviously this only works if the antenna is not built into the innards
of the radio.

The only way you will know for sure would be to try one and place your
radio near it.
When I was a baby (1950), our family lived in Northern Wisconsin .
This was in the days when there really was not much other than AM radio.
I was told they could just barely pick up one station.

Interesting observation and I just tested it myself with a portable
radio and if I got within a foot of the cfl you could not hear the radio
with all the static. Also noticed it on an incandescent bulb but had to
get within inches for the same effect.
With the cfl, static started about 5 ft away and I suspect with your
weak radio signals, cfl static would overcome it easier.
With an LED flashlight, I saw no effect on radio.
I would guess that some cfl bulbs are worse than others as some I have
give off a humming sound.
My regular fluorescent shop light gives more radio interference until it
gets fully fired up.
I lucked out today.
Did some computer repair work for a guy in the lighting business
and in lieu of getting cash I am going to be getting a number of full
spectrum fluorescent tubes and fixtures plus some CFL full spectrum lights.
He said that LED's are too expensive . I hope eventually the price goes
down...but after my last combined gas and electric bill I realize that
most of my incandescents will have to go.
I've replaced most of my incandescents with CFL's. LED's don't use that
much less energy to justify their high cost compared to CFL's.
With their longer lifetime, I really like CFL's in those fixtures hard
to service like those in the kitchen where glass must be removed to get
at the bulbs. In bathroom fixtures where you only spend a few minutes
and lights are on and off frequently, CFL's do not last nearly as long.
I've got a powder room with original incandescent super bulbs in them
nearly 40 years old.
I am just starting to like CFL's as I found a small sized 100w
equivalent that I was able to but in an antique light fixture in my
office. I had a low wattage incandescent there as I was worried about
Hoarded some incandescent bulbs from the store shelves. As of Jan. 1
this year legally no more selling of incandescent bulbs. Specially
I collected enough spares for our chandeliers. Will wait out until LED
ones price come down low enough. Mostly I use daylight CFLs.
I have a number of antiques chandeliers that I put "reproduction"
antiques bulbs in. I am assuming that since they are a specialty item
they will be exempt from the ban. CFL's will /not/ quite make the grade.
I have a desk lamp on the kitchen table, so I have enough light to read
by, and in the summer it got so hot I couldn't take it anymore. 100
watts. I changed to CFL and all is good.
Yes, despite what ABC TV News said, only the standard shape (actually 3
or 4 shapes, but all very similar) is banned. All the dozens or
hundreds of other shapes are okay. I wonder what percentage of the
market they are/used to be.
The deal (reached back in 2007) was to regulate only the bulbs that used the
most energy. I don't know the total percentage of the total bulb market
involved; but the 40 watt and 60 watt household bulbs are about 60% of the
standard bulb market.
Yes, incandescent floodlights are regulated and some types have been phased
out; but manufacturers were already converting such bulbs to high-efficiency
incandescent-halogen technology and so just went ahead with their plans. I
haven't seen any consumer articles about floodlights for some time and there
hasn't been much mention of them on this ng either.
Wow. Well I've been dissatisfied with floodlight life anyhow. One of
my fixtures is 20 feet up the side of my house and it's hard to change
the bulbs. Are the halogen lights more long lasting.
Last time I just wanted to adjust the settings on the sensor.
I disconnected the Romex in the attic, took off the nut and washer
holding the screw and lowered the whole fixture to the ground (tying
some string onto the Romex to make it longer). Did the stuff on the
ground and then went inside and pulled the whole thing back up. The
hard part was getting that screw into the hole, so I could put the
washer and I think I changed to a wingnut, on. It took about 10
Halogen floodlights are often rated for 2000 or more hours instead of 1000
or 1500 hours for standard halogen bulbs; but what that life rating doesn't
say is that halogens are more sensitive to shock and vibration than
non-halogen bulbs. When I adjust halogen bulbs in track lighting, for
example, I turn the lights off when I aim the fixture so the hot filament
coils don't get shaken, weld together and shorten lamp life or cause the
bulb to fail. The 50 watt halogen floodlights have been the worst in that
respect. Outdoors, if the fixture vibrates or shakes in the wind, that's
probably going to shorten the life of the floodlight bulb.
Weatherproof LED floodlights ought to be the best choice for your outdoor
fixture situation; but, considering the cost, buy an Energy Star bulb to get
the strong life warranty and you have a good chance of never having to
replace that floodlight bulb again.
Considering how LED has come along, I'd consider it as the replacement.
Still expensive,but it if lasts a long time it is worth it not having
to change bulbs in tough places.
I see one in my neighborhood. I like the brightness and quality of the
light. I see it on my way to work in the morning and it is too cold and
too early for me to stop and check out details.
