Hi guys!
I'm working on a high-voltage generator which uses a flyback transformer as the output stage. Flyback transformer circuit diagram is shown in Fig. 1.

Fig. 1. Flyback transformer. The diode is internal.

Fig. 2. When a fluorescent tube is connected to the negative terminal, it lits brighter.

Fig. 3. When it's connected to the positive terminal, it's dimmer.

Why is that so? Any explanation?

Greetings

I believe that current flows through the lamp because of capacitance to earth. It doesn't take much to light a florescent lamp or LED. Calculate the capacitance to earth then the current flowing through the capacitance.
