You would be suprised. I fitted 3 12v MR16 dowlighters above my sink and they knocked out the DAB radio in the next room which is wired in to a dedicated external areial on the other side of the house. The signal was 100% on every channel and it was reduced to zero.

I just had to pay more for better quality in the end.
 
Hi, I did this mod & have noticed that I have been losing the DAB signal when indicating, could someone please tell me which bulbs they are using to eliminate this please?
 
If they are bs marked they shouldn't do this as they should be EMC compliant
