Is there a way to prevent flickering in fluorescent lights?

[@Meskel_light]

You can use electronic ballast to eliminate this effect. When it comes to recording, I recommend a SLR camera that does not record the flickering effect like a phone.
You can also set the camera's fps according to the frequency of the current. For example, for 50 Hz it will be 25 fps, for 60 Hz - 30 fps. Then flicker does not occur, but horizontal stripes appear.

@@Meskel_light Thank you for responding. So is there a way to reduce or eliminate flickering with mechanical ballast?

[@Meskel_light]

@@vartex4488 With magnetic ballast this is not possible. The use of a capacitor connected in series can cause two fluorescent lamps to flicker alternately, but this effect will never be eliminated with a conventional ballast. In this case, only the electronic ballast remains.

Probably the metal table is causing it

[@Meskel_light]

This is not the fault of the table, because I removed it from the fixture precisely because of this noise. This is an old Polish ballast. It's very durable, as it's been running for 50 years, but it's noisy and has a loss of about 10 watts.

Oh what caused it tho

[@Meskel_light]

@@Yanyan_isnothere I think it had to work on a short circuit for a long time and overheated

​@@Meskel_lightno its normal for polamp inductors. I have one with 20 and one woth 40w and both are also very noisy

[@Electromaniac420]

​@@Meskel_light10 watts loss is good. Zumtobel has 12w loss
