General high-speed discussion / Re: driving low pressure sodium lamp without 60Hz flicker

I had a similar Problem with my LED-Lights.
Most of them are Pretty Cheap ones, and most of them Flicker a lot.
So i built a litle Box to Plug in between my Lamps and Mains Outlet.
Just a Simple rectifier and Electrolytic Capacitors and Ceramic Capacitors to Filter out all Riple.
Use Big enough Capacitors to get rid of all Voltage Ripple, Size depending on what kind of Power your Lamp has.
I would also recomend adding a Fuse, and a 100K Resistor to Discharge your Capacitors to Avoid Harm from Loaded Caps when unpluged.
The Diagram pictured Below is what i use for LED, don´t Know if that would work with your electronic ballast and your type of Lamps.
If the Ballast unit is not too expensive, and easily replaceable, maybe just try it or Work your Way up with the Voltage with a variac, like Tesla500 said.
Should Work for any Device or Lamp, that Uses DC voltage internaly anyways after a (cheap or poorly designd) rectifier stage.
For me this Works great, and i never had any Problems again with any Flicker on my Slow-Motion-Clips.
Use this Circut only, if you know what you are doing and on your own risk.
