Very many electrical equipment and fluorescent lamps powered from 230V AC have a filtering capacitor on power input between live and neutral. This is typically there for interference suppressing. That capacitor is normally X rated “self healing” type, but they can sometimes fail. When they fail their case starts turning black, and they can start →
