Have you talked to the owner? What does he think can be done?
Have you contacted the ARRL? The League will no doubt have received many such
complaints already.
There is an FCC page for reporting complaints; are AMBC stations you listen to
interfered with by this lighting? Call them; they have their own route to the
FCC.
If you do contact the FCC they will want to know if you have talked to the
owner and what resolution (or lack thereof) you reached. For that matter, so
will the ARRL.
Some manufacturer say they try to prevent interference (examples):
Toolstation Electronic Transformer 12v 105w
Radio interference suppression with overload and thermal protection. Dimmable
with standard dimmers. 60w only?
The Flick 3000is silent running, therefore has no interference noise commonly
associated with low voltage dimmers.
(Note: UK firm)
Omn60Lt Undercabinet By American Fluorescent
Compact omn60lt electronic premium high-end transformer features integrated
radio frequency interference suppressor, short circuit protection, overload
protection, overheat...

Comment:
The traditional recourse of replacing switchers with 120V/12V transformers may
not be available to us much longer, as efficiency regulations are resulting in
SMPS replacing even low-power transformers. Unfortunately, many
manufacturers, importers and vendors don't care if these are either quiet or
safe. One sometimes sees recalls for counterfeit UL marking but hardly ever for
radio interference. That may be a subject for another thread.
