Then come back and tell us how unrealistic their numbers are.

Dan,
You come across as challenging the facts, but, you provide few facts on your
own. It's easy to challenge, but it takes effort to back up your challenge.

How does the cost of a Kwh contribute to the rated lifetime
of an LED-based illumination device? I smell a red-herring.
Costs of electricity vary widely nationwide. Yes, California
has more expensive electricity (specifically to encourage conservation)
than other parts of the country, but that is not a factor in
rated lifetime.

Tj and cycles (on/off) would seem to be the two major controlling
factors, just as they are for incandescents.

Tj = Junction Temperature.
