The article talks about street lighting as well so its not just strictly transport.

So what are these LED street lights like then? How do they compare with ordinary ones? i should imagine they use much less juice.

That's right, but their light output is the same, except white. For an idea take a look at the
Blades car park. I hope to god these guys are involved, being Sheffield based and all...

Constellation Lighting Ltd.

My road in Corby is fully lit by LED lights. They're bright but unlike the older lights, there isn't as much light spill, it's far more concentrated. So depending on how far you space them out, there could be dark spots.
Amey are required to design to British standards therefore they will be no dark spots. They will appear whiter and brighter as a lot of streets do no currently achieve current lighting standards. As you say dinp the control of the light is better therefore you get less "spill".

= less light going up, so better for astronomers, and out, so better to enable me to sleep ;)

You should take a visit to Northamptonshire then my friend.

We're in the rather bad position of having the equivalent of 50% of our existing lighting stock turned off, which you may think is 1 in 2 lights in each area, but no. We have urban dual carriageways, traffic lights & junctions near schools, cycleways and entire industrial estates in total darkness. Every single light turned off. No cats eyes, no white lines along the sides of the roads to compensate, just total darkness and a nightmare for drivers, cyclists and pedestrians.

What they're apparently doing is a 5-yr programme to replace the entire county's lights with these new LED ones. It started last year and the very first street they did in Corby was in a Conservation Area. Tall lamp columns on tree-lined avenues, more spaced apart than the previous lights were. The result... dark spots. Lots of them. Even on the non-tree lined streets, where these new columns have been installed, there are dark spots. So if there are any British Standards then please can somebody inform Northamptonshire County Council of them. Because at the moment, they seem to want to stop people walking or cycling anywhere in our county.

And the best bit of all... as the county grows, the council will not adopt any street lights from new developments. So welcome to the future. The slogan is the opposite of that used by a certain mobile phone company.

I don't know the ins and outs of what is in the NCC/Balfour Beaty contract so can't really comment on that. But it sounds like that lighting contract was cut back considerably which means compromises had to be made. These have been instructed by the council probably as part of budget cuts. The Sheffield maintenance contract includes trees therefore the whole street will be considered at the same time i.e. consideration of tree replacements at the same time as lighting design. Sheffield are in a very good position with regard to this contract. Never say never but the budget for the contract appears to be very much ring fenced.
 
Very glad to hear it. Cannot quite put into words just how much ire I have towards Northamptonshire County Council, but I assure you there is a lot of it. Because we have a two tier council system there and I work at Borough level, any good planning work relating to highways/sustainability we do can be, and is being undone by the County, who have sent us back to the dark ages.

From my time in Sheffield, it is obvious that there is a more forward-thinking attitude to highway design. I just wish the same could happen down here. Will stop talking about it before I wind myself up!
