Part 18 exclusively addresses ISM equipment: Industrial, Scientific, and
Medical. As far as lighting is concerned, Part 18 specifically addresses
ONLY "*RF* LIGHTING" which is the only lighting option present in Part 18.
Certainly a florescent tube excited to emit light on 60-Hz is NOT "*RF*
LIGHTING". I fail to comprehend how and why a florescent ballast would
come under Part 18. Florescent lighting is not "*RF* LIGHTING". Possibly
a florescent tube excited to emit light by a Tesla Coil or a close-by AM
broadcast tower (KOB AM in the North Valley of Albuquerque) would/might
come under Part 18, but not standard home florescent lighting.
