Would a standard fluorescent fitting work on DC

Would a standard fluorescent fitting work on DC. Of course it would but a certain type most of you have never seen with a balance lamp for starting and changeover switch control. The reason I ask is  at one engineering factory switched off the 3P main  switch to check the mains fuses type and size, the high bay lighting (fluorescents ) did not turn off instantaneous but went out at random . Put it down to a connected capacitor bank supplying voltage. How could that be as the capacitor holding on  voltage would be DC.  That was a long time ago but am sure this situation would be more noticeable now with low wattage LED lighting. his post may not be at all relevant and I am not sure i understand it all, but it happened.    

Bleed resistors , it is my observation when was inspecting main switchboards at various factories (insurance inspections) that some resistors  on capacitors were burnt out or missing or one leg of the resistor sticking up in mid air. The can ones all you could look for if any are pregnant or the proper name any with top hats, don't know about the bleed resistors on them.

  • I  did the experiment with using a filament lamp in place of the choke it seemed to work ok the starting  time was a little longer and using a 20 watt tube a 100 watt lamp ballast made the tube slightly dimmer than normal but a 150 watt lamp seemed to run it at near full brightness. There was however a noticeable flicker at the tube ends which is much less with the choke ballast in the system. Regarding CFLs I ran out of ne with around 330 volts DC  input and it seemed happy enough switching off the power with around 300 uF of caps gave around 4 or 5 seconds of light until the caps run down
