Absolutely no!is 250 _300 turn coil enough for 230v 50hz primary to not be short cct????
If you want to make your own transformer you must calculate how many turns are required for that core.
Start with the millihenries of the choke and the current when the choke was in the light fixture. You can calculate these from the information page for the light fixture.
For example, If 300 turns made 35 millihenries you can calculate how many turns you need to get the inductance up to the right amount to limit the main current. Then you can decide a wire size to carry the current required for the power you are designing for. The cross sectional area of the primary winding should be equal to the cross sectional area of the secondary winding.
That's all I have for this project.
