Please see the messages below.
My interest in amateur radio prompts me to ask if anybody on the list has
experienced interference from their LED lamps?
I'm trying my best to keep switched mode power supplies out of my house and
have totally excluded the so called electronic transformers from my
lightin=
g
system.
I'm obviously interested in moving over to LEDs in the future but I most
certainly don't want to be introducing anything that will cause me
interference.

Thanks

Tracey
