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 have successfully run 240v rated CFLs from as low as 72 volts (12 x 6v camera batteries in series, I got a batch of them cheap at an auction, past their expiry date but still fine). Served me as a handy work light for a few years . IIRC I had to try a few different lamps before I found one happy with the (comparatively) low voltage.


    Now superseded by the LED floodlight retrofitted with different LEDs and a 12v SLA battery :)


    Can't be doing with this newfangled lithium stuff <grin>
