Another good source of low-noise lighting is marine hardware stores.
I owned a sailboat for a while.  Sailboats are floating radio
stations.  I had Marine  HF and VHF and Radar all running off banks of
lead acid batteries.  You have the same noise issues on the water as
in ham radio stations.    So many of the lighting products are
designed to be radio-quiet and will say they are "quiet" on the box.
The LEDs are good, if the power supply is "clean"  but like all power
supplies you have to check.

Actually the CFLs are radio quiet too it is the little power supply
built into the base that makes the noise.
