Cree Lumens/amp?

What is a good source/ thread for the lumens produced by the various Cree bins at different amp rates. Ive found the mfg 350mah info... but how about when we drive them harder?

there is a graph, that shows correlation output with increased current (in %)
with a little bit of calculation it can be estimated
(cant open Cree site atm, so I can not give info on what page. iirc its in the product documentation, not in the binning pdf)

In the White LED lumen testing thread, page 4 has the Seoul P4 LED and page 5 has the Cree P4, Q5 and Rebel 100 LED. Q4 evaluation has the Cree Q4, Seoul P4, Cree P4 and Rebel 100 charts.

its in the less visited LED forum (not led flashlight but raw leds)

or about any other thread that Evan, Newbie , and the rest of the graphing and testing crew work on.

there is a bin chart around somewhere, but as far as COLOR bins, "warm" whites put out about 1/2 lumens (look like less light)
and bin jumps are about 20 lumens here and there, like p4 to q5 is 20 if i remeber right.

some USER opionions of the vast increases after all who cares what the specs say if it doesnt pan out into reality.
