Blinded by the light ;-)

Talking of which, anyone have any idea how much current in amps one 
of the the large flash bulbs (size of a domestic light bulb) takes to 
fire it? I feel some artificial light coming on and want to set up 
some retro flash heads. The Graflex type guns take a few large (D 
size?) batteries, can't remember how many off hand and am too lazy to 
open the case containing the flash gun. They would be capable of 
delivering a hefty amperage though.

Have seen the results of arcing on the flash contacts on Graflex 
shutter blinds and am thinking about using a small relay to fire the 
flash bulbs with a much lower current being drawn through the shutter 
to actuate the relay which will then fire the bulbs. Don't like the 
idea of trashing the flash contacts in shutters.....

Before anyone asks - yes the shutters I am thinking of using have a 
bulb setting.

Cheers,
