I recently replaced Halogen under-counter kitchen lighting with Xenon types.
The units purchased do not use switching technology and have better
compatibility with a light dimmers. Purchased at Home Depot and the plastic
blister pack states "Does not cause radio interference." They're completely
clean and use good ole' fashion resistive current limiting.
Hampton Bay 6-Light Black Under-Cabinet Xenon Puck Light Kit
Model # EC1333BK
Internet # 202051199
Store SKU # 81831
Speaking of dimmers....I have replaced all Leviton-branded dimmers with
Lutron. Huge difference. The Leviton dimmers even stated "RFI protection."
What ever RFI abatement Leviton uses is minimal. I can detect no RFI with
the Lutron brand.
