This can happen where conventional halogen lights are replaced with LED lights as this substantially reduces the load on the transformer (normally of the electronic type, using a switch mode power supply), which in turn can then become a cause of radio interference.
How do I stop my LED lights from interfering with 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 do LED lights make my radio static?
Specifically, the source of RF interference refers to the technology that emits light or electromagnetic energy. The materials can be due to the light bulb, transformer, or ballast used. Then, it is conducted or radiated due to a cable or the ceiling itself.
Why do LED lights interfere with DAB radio?
The most common source of interference to DAB is from LED lights. Many people are now using low-power LED lights instead of more traditional varieties. … This is because the transformer would have been designed to operate at higher power and not the lower power used by LED lights.
Do LED lights give off radio frequency?
FAQ – LED Radio Interference Issues
While the Light Emitting Diodes themselves do not generate any detectable noise, the switching power circuitry driving the LEDs operate at high frequencies, which, when not properly filtered can result in electromagnetic interference.
Do LED lights cause RFI?
While the newer LED bulbs seem to be gaining in market popularity, both types of bulbs can contain electronics capable of causing RFI. … LED bulbs op- erate under Part 15 of the FCC rules. Typically, they are classified as an uninten- tional radiator, if their internal circuitry is operating at greater than 9 kHz.
How do I stop static on my radio?
How to Get Rid of Static on an In-Home Radio
- Try an antenna. For FM radio, antennas range from the dipole and rabbit-ear types for less than $10 to roof-mounted antennas for more than $150. …
- Relocate your radio. …
- Turn off electronics near your radio. …
- Switch to MONO FM. …
Do LED lights interfere with Bluetooth?
All electrical devices, including LED lighting, emit electromagnetic radiation. However, the field generated by an LED light is not strong enough to cause interaction with WiFi or TV. On odd occasions the unshielded wires can produce a weak electromagnetic field, that might cause disruption.
How do you stop radio interference?
Stopping It. There are two basic strategies to control RFI. The first prevents it from coupling in the first place by using filters or arc snubbers at the source, relocating equipment or rerouting cables, using signal path ground isolators or adding shielding or ferrite chokes to cables.
Why do LED lights interfere with TV reception?
It turns out that using certain types of LED light bulbs can cause interference with some frequencies. The LED pulses on and off at a very high frequency (beyond that which our eyes can perceive), and this pulsing can create RF noise. If not shielded sufficiently, this RF noise can interfere with TV or radio signals.
What frequency do LED lights operate at?
Since then, multiple shades of LED lightbulbs have been discovered. Light frequency is measured on the Kelvin Scale from 1000K to 10000K, but most commercial lighting ranges from 2000K to 6500K.
How do I stop my LED lights from interfering with my garage door opener?
Possible solutions include:
- Switching to a name-brand LED light — look for a Federal Communications Commission (FCC) logo showing FCC compliance, including for minimum radio frequency interference.
- Changing the garage light fixture to a less energy efficient option.

Do LED light bulbs emit radio waves?
Mains LED lamps employ an integrated switching controller to power the LEDs from the high-voltage mains supply. Poorly or cheaply designed controllers can emit wide-spectrum electromagnetic RF noise because of unsuppressed fast switching signal edges.
Do LEDs have a frequency?
The electromagnetic frequencies of light emitting diodes range from under 400 terahertz to over 600 terahertz, corresponding to red and blue light, respectively.
Why do I get interference on my radio?
Interference may prevent reception altogether, may cause only a temporary loss of a signal, or may affect the quality of the sound or picture produced by your equipment. … The two most common causes of interference are transmitters and electrical equipment.
