I changed the screw-thread 60w tungsten bulb for an 11w low energy
job and now it won't turn itself off. Any ideas why?

A fundamental difference between regular tungsten lamps and
low-energy ones it the current required to light them up.

A tungsten lamp is a low-impedance device, which requires a reasonable
amount of current to light up.

A low-energy lamp can illuminate with a minimal amount of current :
even minimal leakage current in some cases.

It seems that the PIR switching device has enough leakage current in
it's 'off' state to light the low-energy lamp.

You need to change the PIR device to one with a lower leakage, or put
back the tungsten lamp, or do some electronic trick-****ery perhaps
involving a relay, or spoons.

Buggery ********. Ah well, I tried to do my bit for the world and it farted
in my face. Arseholes to it.
