Follow up on LED streetlight article

In a previous post, I talked about Ann Arbor, MI's intention to convert all of its streetlights to LED lights in an effort to save money and reduce global warming emissions. A copy of my post was put on a local blog since the town was considering replacing its streetlights. The idea was immediately dismissed a untenable, too expensive, silly, etc. In researching further, I found this article on a major city that has already installed them and they work. It just shows that all towns, villages, and cities across the world should follow this lead and install them immediately.

Thoughts anyone?
