I am trying to find a security light that has 3 settings:
1. on/off by PIR
2. On
3. Off.

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 ?

Any that you can get inside and hook up a separate live and neutral
direct to the lamp, bypassing the PIR switch.
