The message
from "gentlegreen"
contains these words:

I want to fit a PIR in my new stairwell to switch the lights on. I
suspect I
will use a bog standard B&Q security light minus the light - I'm
guessing
specially-designed "occupancy sensors" are expensive.

The ain't cheap. I have one in the downstairs loo.

Oooh, look, while googling for a price I found this...

A security light that does LE lamps.


I suspect I will modify a cheapo Halogen light and wire it in parallel with
the light switches in such a way that I can painlessly remove it in the
unlikely event I ever sell ...
