WiLL makes the CHX and XtraLight makes the CitySaver.

I personally have (or anyone else has, for that matter) never seen either of them, so I ranked them judging by the companies' quality virtues.

the LED roadway deserve S tier and I have seen them in the Caribbean and just found out the original satellite was installed down under and later the nXt made it to Australia
MB Hydro used the nXt mini in laneways and near zero failures 

The satellite series is quite rare here, however some did make it. The nxt series is I would say most common in my city, Canberra (compared to the rest of Australia) , they installed the nxt-m on larger roads from about 2016-2018, I uploaded a picture of my example earlier today if anyone is interested. There are also nxt-s and nxt-c installed in some new areas too. Some 158w nxt-m made it to some Queensland motorways as well.

Yeah, Dialight makes the StreetSense and the ProSite. Extremely expensive but well-built luminaires.

They appear to be discontinued now... the product page now redirects to a 404 not found for both luminaires.
