We have had LPS lighting here as far back as the early 60s, indeed I grew up with the change over from mercury lamps to SOX, it was also the LPS lamp that got me interested in lighting in the first place.
It must be an age thing with me though, I hate the colour of them now

I take our dog out at 5 each morning, and walking from LED lit roads to SOX lit roads just looks awful!, one of the reasons SOX was used at night, (apart from the 70s energy crisis), is the human eye achieves a higher visual acuity under its light, this was one of the first things I remember reading about them years ago.
However I do find myself questioning this now!, as I have always had good eyesight until I turned 40, when it starts to go downhill!

, but I can see so much more under 4000K of LED lanterns than I can under SOX now!,
due to LEDs sharper light.
For instance, a bush by a gate post in the distance can look like a person standing there under 1800K of SOX, as they make everything look a dark black/grey, (Ash, my slightly antisocial German Shepard doesn`t really do random people standing in gateways early in the morning darkness), so I usually cross the road to avoid a nasty surprise!.
This situation improved slightly with HPS lamps, but a bush/person under LED looks like a bush/person as your eyes can see what it really is in white light!
As for not wanting to lose SOX street lighting, sadly there will be no choice in another 3 years, as there just won`t be any made to keep using!
Your right about the `council bean counters` Sammi, but I`d be interested to know what make/model of LED street lighting they have started to install in your area, that make them so bad?
Our council tested just 3 lanterns in different roads last year, No1 the DW Kirium, (just nasty shocking glare bombs)!, No2 Urbis`s Ampara, (ugly and with a tendency to let water in)!, and No3 Philips`s Uni-Street.
Philips won

, and no surprise really, as the Uni-Street is perfection as far as LED lanterns go, good output, good colour, not glarey, and their a smarter design on the end of the poles than all the others.
This time last year Cheshire East started to fit them in mass, and now their almost done, out of a 100% SOX lit streets in my town, we have just 7 SOX left in service, and 3 SON!
