Simon, I used to buy flashbulbs by the case during the 1950s. Almost all my advertising illustrations required multiple lighting arrangements, often with mixed sizes (#2 were the big boys, then #22, then #5, and finally the "peanut" size). We'd diffuse the intensity with one or two thicknesses of a hankerchief in front of the reflector. The power source was three or four D-cells in the flashgun, so we didn't have to look for an AC plug anywhere.
