Please help, one of my bulbs is also flickering, it's not the bulb because I have three of them and when I position them on the other side it works normally, every time I change the ballast complete with the bulb. I am in Croatia and currently I don't have an answer on the local forum.
What I know - it's not the bulb and the ballast
What I don't know: - why is it flickering, does anyone have an idea?
