newwwwwwwwwwwww! idea for replace the fluor

[yar]

HI'
I replace the ballast of the fluorescent lamp with capacitor the
tube is 20watt '60cm worked at 220 volt I replace it's ballast with a
capacitor 10uf 400 volt non polar the tube give a light but the light
is flash the frequencey is 50 hz is there is any modification to
overcome this problem ?

thank you for any help

There are a good number of reasons as to why a ballast is used (older
transformer-like version or newer electronic version).
You have tossed out the engineering by using a simple capacitor, and
wonder what to do?????????
My questions are: (1) are you sane? (2) are you ignorant? (3) do you
not know well enough to leave something that works (and that you
*clearly* do not understand) ALONE?

Yes there is a modification that will work.

Put the ballast back.

And fix the auto-repeat on your keyboard.

Yar-

This is not a new idea. I've seen capacitors used as ballasts with battery
powered lamps, where AC was generated at a high frequency to drive the
fluorescent lamp.

As far as your 50 Hz, isn't that your local AC power frequency? As long as you
use AC with a flourescent lamp, it will flash, but probably at twice the power
frequency. The lamp is not polarized, so it ignites on both positive and
negative voltage peaks.

To get around that, you would need to rectify the AC power, use the D.C. to
drive an oscillator at a higher frequency, and drive the lamp (using a new
ballast) with that instead. Of course it will still be flashing, but at a
higher frequency.

It might be possible to drive a flourescent lamp using D.C., but you would need
a resistor to limit current, which would get hot and waste power.
