Understanding LM-80 to evaluate LEDs

HOW TO ACCESS LM-80 DATA
Despite the fact that LM-80 was created to inform customers of manufacturers’ testing results, many manufacturers don’t allow the public to access their LM-80 data or make accessing the data cumbersome. Sharing the data available online is one way to make it more accessible.
As part of its suite of online LED applications tools, Philips Lumileds now offers an LM-80 reporting tool that enables users to quickly and easily access LM-80 data for the majority of its LED components designed for general lighting. The tool offers customers the ability to generate a custom LM-80 report, tailored to their specific drive conditions. This can help a lamp or luminaire manufacturer streamline their development and qualification process. And because online content is much easier to update than a printed document, an online reporting tool enables manufacturers to keep their LM-80 material current.
In conclusion, to assuage consumers’ fears about LEDs’ long-term performance, manufacturers must make test data, like LM-80 results, available to the public and provide the data in a meaningful, easy-to-use format. Consumers must be reminded, however, that LM-80 is only one part of a larger puzzle. All pieces of the puzzle must be considered to make a fully informed judgment about the long-term performance of an LED-based product.

Typo: "using their own desperate and varied systems."
Should be "disparate".

Oh, I thought they were desperate to get their products out to the market,
and so desperately testing the systems.
I would be desperate, too, if I had to do a 60,000 hour life test with only weeks to go.

Nice to see some sense of humor among us techies!
I hope all manufacturers allow access to their products' LM-80 data.
