Has anyone had experience of the lamps/fittings:

It's the 36W spiral-wound CFL security light, with PIR detector and
timer.

The questions a

How well do they work in cold temperatures?

Is there a mechanism whereby they can be turned on for long periods,
such as an evening, as the timer only goes up to 7 minutes?

The maker's web site doesn't mention these aspects.

I wouldn't buy one myself.
The none PIR version is £16 and you can add a separate PIR for £8.50 from
tool station.
Then you can put the PIR in a sensible place and the lamp in a sensible
place.
You can add more lamps too as they wont be as bright as a 300W halogen lamp.

You can add a switch across L1 and L2 on the PIR (usually at the lamp end
and use three core and earth to the PIR) to work as an on off or use the
built in off for a second and then on to keep it on.

B&Q had some much nicer flood lights with a 42W lamp in them but they were
£40 without the PIR and £51 with.

They also do a 70W halide lamp which is far brighter but not much use as a
security light as they don't instant start.
