Led lights and radio interference

spitz · Sep 26, 2017

Just put some led lights in my shop and now all I get on the
radio is static! Any ideas on how to fix this? Lights are from
menards and are on separate circuits of 12 ga wire. Thanks
for your ideas!

Might not be able to.

Sounds like the switching power supplies for the LEDs are causing RF interference.

You could listen to FM.

check for a bad connection in your wiring.

Put the old lights back up ?

I have went to all LEDs in my shop and have no problems with radio and my radio is on the same circuit as lights. You might have a loose wiring connection or fixture is bad.

All LED lights are not created equal. I have slowly been replacing the bulbs in my house with different types. One hummed terribly another interfered with the radio.

Look up the brand online, see if anyone else has had the problem, if they found a solution.

Might call customer service, a long shot but may have had the question before.

I have the led 2 row fixtures from Rural King. Strong AM stations cause no issue but weak ones do. Cant get that many FM stations also. Also get a little hash on the CB if I choose to have that on. My radio is a car AM/FM radio with an external auto antenna. My shop is metal so the radio reception is not all that good. I bought an extension cable for the antenna and plan to mount it outside. Hoping that fixes the weak AM/FM reception and the LED noise.

Exactly! I've experienced enough issues with LEDs to convince me to not buy anymore.

just changed large shop over to led and also all of house fixtures are now led also. can not tell i did anything different far as radio is concerned. no help. how many did you change out. can you hook and unhook see if find it that way. sounds like bad unit to me.

I have some LED lights and some florescent lights, all, the cheapest I could find. When I had a regular am radio, all I could get was static. I put a computer in my shop and I listen to radio stations with it. I can listen to almost any station in the world, and listen to country music and music from when I was in high school on U tube and no static at all. Also, the computer is a used refurbished computer. Cheap

may be a dumb question, but have you tried turning all the lights off, does the static on the radio go away? If so, the lights are the issue, if the static stays, something else is doing it, like did your electric company put in a smart meter at the same time? the radio waves emitted from that may be your issue. Allot of things can interfere with radio signal.

I love my LED lights. One on each side of my garage door, table lamps, 4 foot units in my family room.

I did have a problem with one that hummed but eventually he learn the words and the humming was gone.

When the lights are out the radio works perfectly.

spitz · Sep 27, 2017

I went from no lights to 4 LEDs. They were cheap ones but I cant get a signal from a station 4 miles away without total static!

i have heard that if put an led bulb in a garage door openener, it sometimes interferes with the remote wireless transmitter. dont know how true it is.

Just one single example that I just measures the inverter frequency at 66kHz, but being a rectangular waveform, it will have many harmonic frequencies at multiples of 66kHz. About the 8th harmonic will get you into the AM broadcast band. I would expect other LED inverters to operate at other frequencies. Simolar problems with compact fluorescents.

1130Leo · Sep 27, 2017

Well, that certainly narrows it down. Now the hard part, unhook one at a time, it could be just one of them has a faulty transformer causing the interference.

Steve@Advance · Sep 27, 2017

I put in a Chamberlin opener at the rent house last year.

The instructions said LED lamps might interfere. Being a rent house, I put in incandescent, just to be safe.

But I have a similar opener at home, it has one LED, and an LED on the ceiling beside it. Haven't noticed any difference in the operation.

RWT · Sep 27, 2017

I put an LED bulb in an old opener (still works) to see how it would work and have had no trouble that I can tell. It is new enough (barely) to work on new remotes.

When you are trying to open it it, it is off anyway. When I close it it may be on or off but I am close to it.

Your problem is caused because some LED lights contain LED driver(not the actual LED light module) that emits to much electromagnetic interference on the same band with your radio. My shop and house are almost all LED except for a few bulbs that haven't been made yet in LED. I also stay away from cheap oddball LED light bulbs which don't hold up.
