White LED lies: It's great, but Nobel physics prize-winning great?

Re: Let there be light!

Bus-stops are disconnecting from the grid. They harvest enough energy from a solar panel during the day, to run timetable illimination and an LED light in the roof of the shelter. I was surprised when I first encountered one, that the shelter light was bright enough to read a newspaper.

Street lights could do the same thing, if only rules would allow the illumination levels to be dropped. At present there seem to be regulations stating that where there is street-lighting at all, it has to be bright. So you get a ridiculous safety hazard on some main roads, where you get dazzled driving into a street-lit section, and then have lost your night-vision adaptation when you drive out of it. Maintaining the whole road lit to the brightness of a full moon (or maybe just a little brighter) would surely be safer.
