Kudos to the author for writing about a necessary and important subject. Given the fact that LEDs are about to take over in hundreds of new applications in the next ten years, ranging from automobiles to aircraft to medical equipment, a primer on this subject is badly needed.

The information presented is certainly very useful, and presented in an interesting and usable manner. But the information about heat removal is missing, it appears. Since heat is the primary challenge in LED lighting, it is important, even vital, that anyone designing LED lighting understand both the heat generation and the heat removal mechanisms. After all, the selling point of the more expensive solid state lighting systems is reliability and long life, the two things that heat limits most.

I'm visiting a customer on the East coast this week.  While driving, I've noticed that the city opted for LED traffic signals.  They come to one's attention because about 30% of the LEDs in the lights are non-functional (the green lights are quite noticable).  Is there really a longevity gain by switching to LEDs?
