How do I stop my LEDs from interfering with my radio?
How To Fix Radio Interference from LED Lights
- Use a quality LED bulb. …
- Change the transformer to one with better EMI suppression, such as our Verbatim LED transformer.
- Shorten the cable length, and if possible use a shielded cable.
- Add an EMI filter at the input / output of the transformer.
Why does my radio not work with LED lights?
Q: Why do LED lights interfere with my radio? A: Poor quality LED lights to have very weak EMI suppression, despite the regulations governing electromagnetic compatibility that exist. Most often, the electrical ballast of the bulb is the one to blame, as it emits electrical signals.
Do LED lights affect FM radio?
LED lighting is an energy efficient source of illumination that is becoming increasingly popular. However there have been many reports of interference to radio reception from these lights. This can affect AM, FM and DAB radio reception, so please check if your lighting is operating correctly.
What causes radio interference?
Radio Frequency (RF) interference is caused by transmitters on the same or similar frequency to the one you’re receiving — for example, baby monitors, cordless phones, amateur or personal radio transmitters, oscillating amplifiers (like audio or radiating aerial amplifiers).
Why does my radio buzz when I turn on the lights?
LEDs can interfere with audio systems and cause speakers to buzz. This is usually due to a ground loop problem, radio frequency interference, or low-quality unshielded wires.

How do I reduce FM radio interference?
For FM, in some instances relocating your aerial to a new location, through placing a barrier (eg, roof or house) between your aerial and the interfering signal, may lessen or remove the effect of the interference. A change of aerial height may also reduce the effect.
