Compact Fluorescent Flashing.

Zoomup
My friend still has a collection of compact fluorescent lamps. He has a coiled glass style one in his outside light fitting. It is time switch controlled. It was working well until.....wait for it.............wait for it. Today as it was getting dark and before it had switched on, it was gently strobing dimly. It was regularly lighting dimly and then turning off etc. I suppose the frequency was about 3 Hertz.


Has this strobing anything to do with me connecting up his main earth terminal to the official previously unused U.K.P.N. P.M.E. earth terminal? (All main bonding is in place).


Or, did I just not notice this strange strobing before?

    I remember sitting on a London Underground train some years and watching “black rings” rolling along inside the fluorescent lighting tubes.




    Some of the older trains used to  run the tubes direct off the DC traction voltage. all the modern ones have a switched mode supply 'HF ballast'
