They might, but once you go below the ignition threshold they'll just sit
there dark. Might even damage ignition circuit.
Driving anything out of specs is a *BAD* idea. Most devices are not smart
enough to cut off when power goes out of bounds.

Of course, thyristors hack your nice slow sinus into lots of rapidly
ramping-up pulses. It's a duty cycle thing essentially; how many on vs.
off states of the waveform available (typically, AC sinus). Anything but
classic ohm load doesn't like this one bit.
