"...expected lifetime is set at 45,000 hours -- just slightly more than a CFL's 10,000 or a standard bulb's 750 hours."
Is 45,000 really "just slightly more" than 10,000 or 750? What is your definition of "slightly"?

For home use, the price is still very high. For commercial uses, where replacement costs include labor, and where power costs are generally higher, this is an investment that will quickly pay for itself. LEDs use less than half the power of CFL's, can be dimmed, emit even less heat, contain no mercury, and last for decades.
Still, the Cree LR6 remains the best, most cost-effective replacement I've seen yet. I just don't use enough 40 watt bulbs to seriously consider this one. Now, if they make it in a 100 watt equivalent, we can talk.

I can comprehend that the LED chip itself can last 45,000 hrs. How about the components inside the bulb? Do they offer a 45,000 hrs life span? I have doubts on that.

45,000 hours translates to roughly 5.1 years of continuous light. pretty impressive considering it doesnt overheat.

The whole world would shift to LED lighting as soon as 2015, that
would save 160 megawatts of electricity annually. In cash
terms, the savings amount to 17 billion U.S. dollars. www.svetorezerv.com
