pretty sure we’ve seen motion-activated brightening lights in the local area for 10 if not 20 years

Continually turning lights on and off is not efficent.

It may well be quite efficient with modern LED lights.

For short duration off-periods with fluorescent lights – it’s not efficient.

And IIRC it’s not efficient with the older types of common street lighting – mercury vapour and sodium vapour – which take a long time to come to efficient operating temperatures.
