CFL internally lighted switch problem?

The problem is in the switch. The way they have the small light in the switch on when the switch is off is by putting it in series with the lamp, across the switch contacts. This method depends on the lamp load being a relative low resistance so the switch light will light up under these conditions, but the large lamp will not.

Put in a more efficient CFL, and even when the switch if off, you get enough current flowing through the two lights in series, the one in the switch and the CFL, so that the CFL gets enough voltage to glow a bit, or cycle on and off.

Try a filament type standard light bulb on the defective lamp. If it lights up ON and OFF correctly with the internal light switch without any flicking light,then the lamp is OK. If not,trouble could be the switch or lamp holder that has a rusty or loosing contact or intermittent broken wire inside.

Cheap made CFL lamp never last long, some could fail in a few week or some were already defective while they were new,or some fails at outside temperature under 0 C degree.

confusing thing. try searching with the search engines. this could actually help!
