Then I don't see why a dimmer should not work. The string probably
has enough in series to drop 120VAC, and the natural diode
action means they only use 1/2 of the cycle. the diodes must have
good reverse voltage breakdown. Peak voltage is 163V. divide by two and
you get 80 bulbs in series.
The dimmer effect may be a bit non-linear, but should work.
