I've just picked up bare bulb head for my Vivitar 4600 flash with ded module 
for Olympus.  With this head in place, the settings appear to be very simple:  
it does a full dump.  No TTL, no auto, just a dump of everything it's got.

The only spec associated with the output is "60 watts/sec."  Vivitar simply 
suggests using a flash meter.  Hey, I would always use a flash meter if I 
actually had one.

Based on 60 watts/second, is there a way other than brute empirical testing to 
ballpark a guide number for this type of light source?
