INDUSTRIAL, SCIENTIFIC, AND MEDICAL EQUIPMENT (Part 18)
When electronic-electrical products are used for providing RF energy for
other than telecommunications applications, such as for the production
of physical, biological, or chemical effects, such as heating,
ionization of gases, mechanical vibrations, and acceleration of charged
particles, these devices fall under the FCC rules 47 CFR Part 18.
Examples include: fluorescent lighting, halogen ballasts, arc welders,
microwave ovens, and medical diathermy machines.

And it *is* RF because the newer switching ballasts ionize the gas above
8 kHz, not 60 Hz. And they are absolutely hideous RFI generators...
