the red XR-E does not exist. what you have there is a red xr-c. Check cree’s data sheets. The emitter on the left is a genuine cree, the one on the right is a counterfeit. .
The red xpe2 is what you should be looking at. The red xr-c puts out a whopping from high bin to low bin 23.5/30.6/39.8 lm/350mA, the xpe2 p3 73.9 lm/350mA. They can be safely driven to 1.4A after that, all you get is more heat and not more light which your graph does support. and if careful attention is not paid to the assembly you will get 20% plus drop in candela after only seconds. The red led’s have a very low Vf requiring the driver to shed alot of extra voltage creating heat that kills the light output.

would they behave in the same manner as normal xpe2 on aluminum vs copper?

Emitter Test Results pt4: XML2, XP-E2, XP-G2, and Nichia219! (along with sinkpad tests)

Folks, Long time no see... Since most of you are now aware of my testing procedure, I'll be brief here. The following is a test of the Cree XML2 on a standard aluminum 20mm star, along with another xml2 mounted on a copper sinkpad. (member vestureofblood was kind enough to send me out these for testing). [image] Graphs speak louder than words, so here they are. The first one is the XML2 on a standard star, followed by a comparison graph between a standard aluminum star and a copper sink…
