A good written article about all the facets of the lighting industry including some cost analysis. Two things I found missing. One is the LEP (Light Emitting Plasma), which is a also a very promising lighting technology, but not often covered in the media. Another point I think crucial for LED is the possible control capability compared to fluorescent technology. With smart detection and bi or tri-level light output settings for LED light solutions at the current 100lm/W show savings at e.g parking is up to 60% alone.
