I queried what was happening in Oxfordshire.
Many thanks for your enquiry, our current lighting policy is to use 3000K colour temperature LED’s on residential roads and 4000K on traffic routes (which is currently being reviewed as part of this project). Our policy is to dim street lights on residential roads by 50% light output from 22:00pm to 06:00am and traffic route to 75% light output from 00:00am to 06:00am.
This is in Banbury. Not possible to turn lights off because I live in suburban environment.
