SUMMARY

The discussion centers on the interference issues caused by expensive UK mains LED luminaires, specifically 14-watt models that are equivalent to 120-watt tungsten and 28-watt CFL lights. Users report significant AM and FM radio interference throughout their homes, despite the products having CE markings and certifications. To mitigate this issue, one user plans to implement delta suppressors and explore the use of clamp-on ferrite filters on the power wires. The community is encouraged to share their experiences and solutions regarding this problem.

PREREQUISITES
  • Understanding of LED lighting technology and specifications
  • Knowledge of electromagnetic interference (EMI) and its effects on radio signals
  • Familiarity with CE marking and compliance standards
  • Basic electrical knowledge regarding installation and modification of lighting systems
NEXT STEPS
  • Research delta suppressors and their application in reducing electrical interference
  • Learn about clamp-on ferrite filters and their effectiveness in EMI reduction
  • Investigate CE marking requirements and compliance levels for lighting products
  • Explore troubleshooting techniques for radio interference caused by LED lighting
USEFUL FOR

Homeowners experiencing radio interference from LED lighting, electricians installing LED systems, and product developers focused on compliance with electromagnetic compatibility standards.

I have just fitted two (very expensive) UK mains - 14 watt (120 watt tungsten equivalent, 28 watt CFL equivalent) LED luminaires in a building extension.

I am now picking up intolerable interference on both AM and FM radios, throughout the house.

Considering the cost, CE markings and other certifications and pedigree, this is very disappointing.

I am plannning to try some delta suppressors and will report in due course. When I take the units down to fit the suppressors I will take some photos.

Meanwhile any comments or experiences welcome.

That is indeed disapointing. Especially with the CE mark, they should be at least Level A emissions compliant. I wonder if it would be worth a call to their support folks...

I'm not sure what a delta suppressor is, but some kind of clamp-on ferrite on the power wires may help. Let us know what you find!
