(OP)
Can any one explain why energy saving lamps (compact fluorescent lamp (CFL))can and do when switched off, intermitently flash. I recently refurbished a apartment fitting all new light with energy saving globes, most of them flash at varying times which is a puzzle to me.

Have just come across a link which might throw some light (no pun intended) on it. http

Don't joke - I live in Australia and Thailand, and can tell you that the flashing lights are a problem in Thailand - the house spirit mustn't be happy and that means you have problems.

The circuit has a problem, caused from the device designers not consitering how there products would be used, or they did not have any idea of how they would be applied in the future.
This should be a wake up call for product designers to be determined to find there product flaws, and problems.
And I've seen worse.

Because there is no netral taken to the switch, this might not have another solution. However, there is a ground to the switch, but you can't use it because it could cause problems with a GFCI breaker protecting the circuit.

Therefore the switched is a voltage division from one times the capactance and load + two times the capactance. Or not very high.
Maybe it's different where you don't carry the neutral and ground, or the live voltage is twice what it is here.
But with the lower frequency you should have less capactive reactance.
Just thinking it through the difference is circuits.

Have a look at a typical UK two way switch arrangement. The switches either connect one end of the common to the L1 conductor and the other to the L2 conductor (or vice-versa), or connect the common to either of L1 or L2 at both ends (off). The drawing doesn't show the earth connection.
My hypothesis is that one of the two 'off' states always results in a conductor at L1 potential being adjacent to one at L2 potential while the other 'off' state interposes the ECC between them, and that the former state allows relatively large capacitve leakage current to flow because of the proximity of the cores within the cable and the length of the cable run. The problem does not occur with single-way lighting because there is always an ECC between the two cores.
