Re: Let there be light!
"Curiously enough, one of the biggest benefits of LEDs is in street lighting."
In desperate economic moves UK councils are already reducing street lighting almost back to the 18th century levels. My large town switches off all the street lights at midnight - leaving only a few high level clusters on major roads. LED lights would be seen as a source of further economy.
The pitch black result is that any late return from an event requires a torch. Possibly an employment opportunity for link boys - or footpads.
