Why does my energy saving light bulb flash lightly after I turn it off. It flashes all night every 2 seconds?

Answer 1

On a 2 wire power system, one wire is "phase" or "live" and the other is "nutral" or "ground".
It sounds like the live wire is not switched off by your light switch.
In other words, the ground wire is the one going to the swich.
I have come across flouresent lights that glowed all night for this same reason. Get your electrician to check. I think you will find that the live wire is connected at all times to your lamp, and the return wire from the lamp to the switch is live (via the lamp) at all times. The capacitance effect of the wiring is allowing the lamp to momentarily flash. But please use your elctrician to check and reverse the two mains wires

Answer 2

I have been using compact flourescent bulbs for the last 5 years, and have never had such a problem. Could be something wrong with the lamp your using the bulb in. Try putting your bulb into another socket - does it still do this - if so it's a faulty bulb. If not, either get a new lamp, or if it's in a ceiling light - have an electrician check it out.

Answer 3

appears like the wiring is reversed polarity to this easy, ie the change is on the return, particularly of the feed OR there's a severe voltage container in the area of the lamp inflicting it to attempt to strike. (excite the phosphors in the lamp) A stick sort tester will come across the stay conductor, which could purely be modern-day with the turn on. I even have considered this in the previous on wrongly under pressure general fluorescent fittings which flickered each and every of the time.

Answer 4

You've probably got the light wired in reverse polarity and the neutral is giving the light a small jolt of current.

Answer 5

It shouldn't - something faulty inside the base maybe... try another one and see what happens.
