LEDs are showing up in more and more lighting applications, for some good info on LED light bulbs, www.DonsGreenStore.com is a must to visit. They also have some pretty good prices.

hmmmm.... vancouver should do that, were putting 14 billion into public transit (to improve the environment and because were getting olympics in 2010) i think getting LEDs everywhere would bring some publicity too.

Hmm. I didn't think that LEDs were in the "twice as efficient" range from typical high-efficiency streelight technology (mercury vapor or sodium.) Wikipedia says "up to 150lm/W for LED prototypes" and 150-200lm/W for sodium lamps, for instance. (although the photos show rather "decorative" style streetlamps that were perhaps were using regular incandescents...)

Yeah, the article is misleading. Some city officials probably wanted to appear "green" and justify the spending. They do have a better color rendition and a faster startup, but there's no advantage justifying the actual price gap, certainly not efficiency.

Some city officials probably wanted to appear "green" because of the big fat grant and the media buzz.

He would certainly have a good chance, but it would depend on the quality of his instructable, and what kind of projects other people submit.

quality... you mean how detailed it is?

That, as well as how clear the instructions are, how good the pictures are, etc. Many good projects are not done justice by the instructables written for them.

Its great to see this kind of thinking finally being implemented on a grand scale. If they could convince the corporate/apartment buildings to convert and put up some wind/solar energy systems as well, I would move there.
