A good number of magnifiers use 22W T9 circline lamps on manual preheat circuits.

I got one at work, but it's a conventional with bimetallic starter. I like it :)

Hmm, the guy running the local batteries plus had two packs of 2 FCL/T4 11w circlines. These might actually fit the bill to try on a small camera for OP, unlike trying say a larger FC8T9.
What's a good ballast to run these on? Tried out a WH2-120-C, but it seems to be overdriving by a lot.

I think a good way to determine this is to know the lamp’s operating current and arc voltage drop and look for a ballast designed to run a lamp that has similar or identical electrical specifications.

From what I have gathered, I think an Advance L-1Q13-TP preheat fluorescent ballast with a FS4 starter might work well, but not sure about that either since I am aware that it probably has a similar operating current to F13T5 fluorescent tubes.

Correction: Finally decided to crack open the kill-a-watt. The Fulham appears to be driving the tube fine, it's pulling 12w. But still instant-start.

Hmm, what's a decent rule-of-thumb to figure out the voltage drop?

From my experience, I would use the probes of a volt meter and have them touch the lamp’s pins while the lamp is operating.

Only if a Vita-Lite is used and I am not sure if those exist in circline and MAYBE a Philips K&B Soft White but if ur doing black and white photography it shouldn't matter, but either way its best if an electronic ballast is used

From what I know of, Duro Test did make some Vita Lite lamps in 22W T9 and 32W T9 circline fluorescent versions.

Here are some 32W Duro Test Vita Lite circline fluorescent lamps:
