I am trying to find a security light that has 3 settings:
Its easy to add an isolation switch to turn it off, but not many seem to have a user override (using a simple wall switch inside the house) to put the light perm on. Anyone recommend a particular model that will do this ?
Essentially all of them - if you wire it using 4 way cable, and connect it up to the choccy block bit that normally connects the circuitry alone to one side of the lamp. Do check that the lamp is switched live first.
IME many do have an override. With some it is a separate switch position, with otheres it is a sequence slected one. So for example turning the lights on-off-on again in the space of 1 second causes them to stay on.
If you use a spearate PIR sensor with an ordinary light fitting then it is simple to wire a two gang switch such that one can turn the light Off completely, or place it into auto mode, and the second switch can override "auto" and force it into "on".
Any that you can get inside and hook up a separate live and neutral direct to the lamp, bypassing the PIR switch.
Mine have this function, can't remember now if they came from B&Q or wickes - just open the box and read the instructions to check before purchase

Obviously 1 & 3 are there by default. As to #2... mine *used* to have a system where you switched the light off then on for 2 seconds , off, then back on again (IIRC). It would then stay on. I haven't actually checked its replacement, but I suspect they stopped providing this facility.
It depends on the model.
I'm guessing that Part L regs may have interfered a bit.
My understanding of Part L is that it is illegal to install an incadescent light outside which will not automatically shut off.
This could potentially mean that newer models lack this 'on' feature, and you'll have to hook up an override switch yourself (easy enough - you need to run 4 core cable to the light, and provide a seperate switched live feed to the lamp).
