This is one of the biggest screw-ups LumiLEDs has made since they *******ized the Luxeon V, and the companies that use their products kept reporting they had a rapid light depreciation, and they denied it for quite some time, before owning up, and they were very quiet on that... Thats where the 500 hour lifetime for the Lux V came from.
Next time, if they are going to make changes (or even this time), they really should offer them in different part numbers. In these days of very high quality semiconductors, a major dimension change like this, without documentation, letting customers know ahead of time, is absolutely inexcusable, and imho, some heads should roll.
I wonder how this made it through their Quality Departments?
I think I'm going to go download the new datasheets to see if they just recently quietly changed some numbers in there...
Of course, they have this catch all phrase at the end of the datasheet, which leaves them free to do whatever they want:
"Lumileds may make process or materials
changes affecting the performance or
other characteristics of our products.
These products supplied after such
changes will continue to meet published
specifications, but may not be identical
to products supplied as samples or
under prior orders."
