friend in my bedroom there is a CFL bulb which shows a typical behaviour as below
daily evening i switch it on, and as normal routine it remains on for 2-3hours and then i switch it off but after switching it off, about 3-4 minutes latter the cfl bulb again glow by itself without any source . this glow remains hardly for 2sec and then it goes off and then again blink after certain interval and this keeps repeating for many hours now what is causing this?
