On the South Coast here with small low density towns and hamlets , hardly any difference noticed in regards to lockdowns, but what is noticeable is the recent replacement of old sodium vapour and Mercury vapour street lighting to LED.
It’s not the type of light source ( LED ) that is the issue here , it’s the design of the photometry in the luminarie that I have a gripe about. Our small low density suburban streets have LED lights selected on a “one shoe fits all” principal. A cul de sac has the same streetlight as a long stretch of wide road. In other words no thought into light spill or where the light should serve the purpose.Most of these street lights in our area have no anti glare baffle or deflector, so therefore the light is blasting out the sides at the same Lumin output as directly down to the road area. I feel for the folk in the cul de sac about 60m
from me as the street light is blasting their front living rooms and bedrooms at the same luminosity as the road.The light is even spilling across backyards to neighbouring streets like mine. A simple well designed street light should not do this , it should direct 90% of the light to the road area.So selection of the most suitable light design for the application is good engineering. Unfortunately the powers that be use a principal of “one shoe fits all” approach to street lighting design and application.Admittedly street lifts are placed at certain restricted distances apart but that doesn’t excuse the correct lighting design principles of light spill. An example of LED light saving technology being waisted with poor design
My 2 cents .....
