I don't believe it.  All the farad sized caps I've ever seen are polarized
and very low voltage--think 2-5 volts, not 480 VAC.  Why would you need the
much energy storage in a light dimmer?  Even power factory correction banks
for large factories with lots of rotating iron don't need farad sized caps.
