The ceiling light in my back balcony started to flicker last June. I tried to ignore it because sometimes it seemed fine. Besides, I am not tall enough to even touch it when standing on a chair. Last week, I just could not put up with it anymore and bought a 4-step steel square angle ladder with my consumer coupons. It is stable and you do not need someone to hold it for you. When you don't need it, you may fold it and it's only about 7-cm thick. I'm glad that the light starter was finally replaced and the fluorescent tube will soon be replaced too.
