Led light Fitting not going off

[Glyn1959]

The replies are going off on a tangent. I will ask again. Would having a single (one-way) switch remove the problem?

Can you provide a reference of other source in support of that statement. That the phase angle between voltage and current waveforms does not affect the accuracy of the measurement. .... Maybe modern meters can compensate for the errors in measurement that power factor introduces to the process.

As winston has said, I think you have got this wrong.

For a start, we're not talking about 'inaccuracies of measurement' but, rather, the difference between measuring VA and Watts. However, to the best of my knowledge, kWh meters have always been just that (i.e. not VAh meters). Even the traditional purely electromagnetic meters (the ones with the rotating disk) which we used for many decades, the design was such that they measured true kWh, not VAh.

Possibly, but not necessarily.

I have started a new thread, Click www.diynot.com/diy/threads/electricity-meters-how-they-work.494700/'] here [/URL]

Your link doesn't seem to work, but I have seen your new thread and will respond.

Back to the OP, which suppressor did you use, and how was it connected, and how long is the switch drop to the first switch and then how long is the 3c&e to the second switch? Have you tried measuring the voltage on the fitting with and without the suppressor fitted?

I have also seen this problem occur when there is damp inside the switch/switches and also where the earth wires in the switch cables were not actually connected to earth. The capacitor from the old light may have failed, especially if it is some years old. Most of these things are 'self healing' and every time they heal the capacitance drops reducing its effectiveness.
