I would imagine the guide number would be highly dependent on your location - 
reflectivity of walls and ceilings, etc... Even regular flashes are affected 
by this to some extent, but a bare bulb would probably be affected much more 
so.

I suspect you are just going to need to run some tests in different venues.

Why on earth wouldn't they set it up for TTL? (rhetorical question).
