You can always power LEDs with a linear supply, if suitably designed,

I'm not sure you are following the thread. If you were, you would
know the question is whether it would cause RF interference.

LEDs themselves don't cause any interference. It is the power supply that
does if this happens. And a SMPS is far more likely to generate RF than a
linear type.

Thanks very much. This may be an option for me to look at.
