Ok, so who's responsible if I break my leg tripping on the step that now has no illumination..? I could carry a torch, in fact there's one in my bag most of the time, but if you're on the way back from the pub, you don't always think of these things, and in any case, street lighting is supposed to light the streets, not just a small pool at the bottom of the lamp post.

Did you ever write a letter to Aberdeen council?, point out more powerful  fittings are needed around the tower block?, or even some on the building depending who owns it?

Not in writing, maybe we should. Oh it's not a tower block, just a 3-storey one.

More things to consider when designing my lighting system are brightness and “reach” of the light. But what is everyone’s opinion on narrowband (monochromatic) amber (1800K) LEDs for street lighting?

@HIDLad001 Those could work but you can also try and find PCA (Phosphor-Converted Amber) LED diodes

LED street lights are bad. Some look good though. HID is better.
Please, watch out for the future. It's not looking good. Loves instruction manuals of any kind!

Those usually have much better CRI, but the CCT is a bit higher like a high pressure sodium lamp. I prefer the 1800K SOX lamp color.

Don't know, I suppose we could ask. As long as it doesn't come off our leccy meter

Interesting about monochrome LED, I really don’t have a valid answer to this  , SOX was monochrome because of what it was, I’m on the fence though as to why this would be needed to be recreated using LED? There’s only been colours in street lighting because of the lighting tech used through the years? What would the ideal CCT be for street lighting?, visual acuity can be achieved best by colours from the total opposite ends of the spectrum, i.e, 1800K and 6500K, however YouTube channel Technology Connections pointed out that sodium lighting wasn’t actually an ideal choice at all! I supposed we’d all have our own conclusions on here, but lower levels of lighting would be a start than super bright?

It would be more to protect wildlife and the night sky, because that’s what SOX lamps were most used for in the US.

Whereas here they were just an efficient answer to the 70s energy crisis!

If they were used for wildlife protection and dark sky use in the UK, narrowband amber LED replacements would probably be widespread.

I guess it’s also a personal preference?, everyone is different, as Ria has said, Sammi suffers from night blindness, so LED and white light don’t work in that situation? Me personally, I noticed something cycling home from work tonight, street lighting here has now become obsessed with very heigh columns with powerful lights on!, going back to our SOX days in our town we used to have just 5 metres concrete columns carrying 35 watt SOX, (lower lighting levels on lower columns), even on the A roads! and as I remember them it was enough for street lighting. Now on these same routes, we have 8/10 meter columns carrying brighter lanterns as if mounting powerful lights higher up somehow illuminates the roads better!

That’s how it is in the US. We have bright lights on very high utility poles with long arms. I have only seen a minimum of 50w LED installed around here, and that might be why I like it.

There’s only been colours in street lighting because of the lighting tech used through the years? White light of the CCT that most LEDs put out is very disruptive to wildlife. Also, the fact that SOX is monochrome means that contrast is excellent, so you see movement more easily. Colour temperature for street lighting shouldn't be an issue for drivers, you have excellent CCT from your headlights. Quote I supposed we’d all have our own conclusions on here, but lower levels of lighting would be a start than super bright? You want low levels of lighting..? Come to our street, what have I been saying..?
