This thread needs reviving…
Why? If Cree changed production process for XP-G2 emitters they could also change it for XM-L2 emitters.

Hi luminarium,
All of the XPG2s I had up till now must have either been from the origonal type or I just didn’t notice the change. However I will throw my 2 cents in. This “upgrade” was not only done to XPG2s, but also to XML2s . Or at least “a” change was made. I never had any trouble with a change in tint, however the output from a single XML2 U4 bin dropped VERY significantly about 3 months ago due to a spike in the needed VF. I tested piles of LEDs from multiple sources to try and regain some ampers, but no luck. Serious problem with XML2 current. Is this happening to you???
I probly would not have even noticed accept I test custom builds like my shorty Maglites before they go out on a regular basis. Out of all the XML2s I have used since then I have found only one that tested out the way nearly all of the ones I got off RMMs first reel last year did.
I just hope when XML3 lands we recover some of that nice low VF as most of my builds use a mosfet driver.
So if anyone has lower or he is unsatisfied with performance of lets say XML2 U4 bin emitters thing could be that Cree changed production process for them.
