When I was quite a bit younger (1956) my folks had a UV tanning lamp
using a sealed quartz tube containing mercury.
A free-running 117L7GT oscillator on the 27.125MHz ISM frequency
vaporized the mercury for a good UV tan. However, raw AC
on the plate and no power transformer didn't make for a friendlier RF
neighbor.

As these use RF they fall under Part 18. From the Finally Web page:
*/RFI/*/. Do Finally bulbs cause any Radio Frequency Interference?/
Our lamps are designed to meet the relevant limits for residential use set
by the FCC. They are tested for both conducted and radiated emissions as
required by Part 18 of the FCC regulations.
