OT Slightly - LED street lighting to be installed in Canada - not long for here ?

The latest locale to join Toronto and Raleigh in the LED City
initiative is none other than the home of the Wolverines, which
recently announced plans to replace about 1,400 street lights with
light-emitting diodes. The city is claiming that it will be the
nation's first to "convert all downtown street lights to LED
technology," and it's hoping to save around $100,000 per year in doing
so. Not surprisingly, Research Triangle Park-based Cree will be
providing the components for Ann Arbor's transformation, and it sounds
like it'll take a couple of years before the $630,000 project is
actually completed. Hopefully, it won't take quite that long before
the Maize and Blue can topple Ohio State again.

Is this going to be good or bad for clear skies ?
