When I first did some high speed flash images with breaking light bulbs a few people suggested they would look better with a glowing filament .



Tonight I opened an older flash , un-soldered one of the capacitor wires going to the tube [ very carefully - about 300 volts involved ] , and soldered a 220 volt light bulb in series with the current that would flow through the flash tube when it fired .
When I had the flash on the low power setting it fired but there was no effect on the light bulb .
However when I put it on full power it had an effect .... too much in fact and I may have to use a flash with decent manual control so I can choose exactly how much energy goes through the filament to get the correct glow .
