flashing energy saving light fittings

[rob-les@tiscali.co.uk]

I have fitted two light fittings, switched via two way switches.

Earthing etc is fine.

Both lamps in fittings are PLD compact 18W 840 G24q-2 4pin.

Problem: when switched off both lamps flash intermittantly!

Anyone have any ideas?

This "flashing" from energy saving bulbs is very common on two way switching.
It is caused by induced current within the strappers. and a voltage build up within the bulb capacitor, when this reaches around 40V it discharges trying to light the bulb, causing it to flash.
You can fit a snubber which discharges the current to earth, but if you have an RCD protected circuit, it will trip.
The other way to solve the problem is to fit a tungsten bulb.

Hope this helps
