RE: [OT] Low Energy Bulbs

["Ward, David" <DAvid.Ward@xxxxxxxxxx>]

The consensus here at work is leakage from the carbon deposits due to
arcing
that occurs when the switch is operated.

A suitably rated 100K Ohm 1W resistor sounds like a reasonable solution,
alternatively a compatible dimmer switch or automated switch should do the
trick too

Replacing switches then asking people to only operate the switch at the
zero
crossing point of the mains :S

Switch is in the live (I know as I ran the cables after ripping out the
huge
mess the previous owner had left !)

There's an earth in the rose, but only live / neutral to the bulb holder,
so
I guess that rules out an earth leakage.
