2 questions:

(1) Are your lights controlled indirectly somehow, e.g., through relays,
or through a switch that bypasses something just long enough to get
the fluorescent light started (like a push-to-start button)?

(2) Could be a grounding problem, especially since you're in a country
with 240V mains. 240V on one side and a high-resistance ground on the
other _could_ light a fluorescent bulb. They're famous for being able
to glow -- weakly -- on very low current if the voltage is high enough.
