[RFI] Interference from Halogen Track Lights - Builder's Junque

[KE2N at cs.com]

I think this is a well-known noise source. I ran into this at my old house with some halogen "puck" lights. At the new house, I insisted the builder put in "real" transformers for all the kitchen undercabinet lights and they are noise free. 

You really can still get transformers made from iron and copper windings, but they cost a bit more ...
