Bulb flickers

[Triumph955]

Hi

Like most people I have fitted energy saving light bulbs, but when I switch my hall light off it flickers for a while. I have refitted the orginal bulb and that stays off with no flickering. Putting another energy bulb in and the same happens why?

Confused????

in case you cant find anything, its to do with capacitance in the 2-way switch wires. voltage builds up and after a couple of seconds, the bulb tries to spark up, but just flickers. Ours does it all the time. watch it closely at a random time when off, and you will see it probably flickers all the time.

The original bulb i take it is a normal filament lamp. these will let current pass all the time - but the fluorescents have to spark up before the voltage will pass. flickering allows the built up voltage to pass across the tube. completely normal.
