NECA – The National Electrical and Electronics Association has this to say about the interference of LED lighting and TV reception.
Why are we focusing on LEDs?
Some models of LED light globes cause interference to TV signals. This interference may consist of a sudden loss of signal or picture quality in a residence or neighbouring house.
In these cases, the ACMA needs to be able to quickly contact the supplier of the globes to notify them of the problem. People experiencing TV reception problems may also wish to contact the supplier to arrange an exchange or refund.
The consequences of supplying a device that does not comply with Australian law can be serious and may risk your business’s reputation.
