Jar, there sure is a bunch of great eye candy for us technical types in this thread. Thanks. BTW, there is a discrepancy [typo?] in your post #207 w.r.t your numbering of the funky emitter; #1 vs #2.
I find the graph you posted in #204 to be interesting. At least with this sample the temperature plus current color shifting very closely parallels the BB planckian locus more so than I recall from data you published long ago for other power leds though possibly this may be just due to the different range of currents in the two datasets.
