Can you measure the output of a flashbulb with a flashmeter? Did anyone make a flashmeter that measures flashbulbs?

In my experience, the Minolta Flashmeter IV and up (plus the late Autometer F variants which incorporate the Flashmeters ambient/flash combination mode) respectively their Kenko successors can handle bulbs gracefully. Older flashmeters for indoor studio applications probably can't - these have gate times below 1/60s and no mode for longtime ambient/flash mix lighting.

Never having had one, I've never tried that with bulbs. If it can meter ambient/flash combinations for arbitrary times, it is bound to have incremental realtime metering, and will handle bulbs.

If it cannot, it is likely that the gate time is fixed around 1/60s - and it will only catch fast bulbs with reasonably accuracy (though you could do tests with a given bulb to determine the correction factor - the error would be constant).
