You don’t say! I don’t think anyone ever thought of looking for information on Cree LED’s on Cree’s website.
Genius, I tell you!

Hello PPtk,I just give a advise,
No worries. I have a sarcastic sense of humor, that’s all.

Just so you’ll know? The guys at Cree can probably learn a few things about their own product from PilotPTK. Look at his build thread on the bumper mount light bar he made for his own use, designed to the nth degree and so much better than store bought models they should hang their heads in shame.
And now you know.
Welcome to the forum.

Thanks for your help. I also neededthis information.

Ok, so does an XML and a XML 2 look different? I think I have a new light thats XML2, but the included booklet lists it as an ’XM-L.” Since this one looks different (no lines in the emitter) I’m thinking it’s an xml2. Anyone have a nice picture of the 2 side by side?
It is not the clearest picture, but here is one I made a while ago for another thread (basically the XM-L has a green backing, the XM-L2 has a white backing:
+1 so cool
Such a nice a information on LED close ups. XM-L and XR-E nicely detail with picture which can be useful for everyone.
LED looks like a better option besides laser lights, in this point of view
Perhaps the following MCPCB can solve the problem of heat dissipation of the lamp.
We can produce these MCPCB, with good quality and pretty competitive price.
Asked a relative who had a macro lens to take a close-up pic of the Astrolux S1’s XP-L LED (3D tint)
I did some macros
Did some photos with my reverse adapter for DSLR
Used Canon Eos 50D with 16-35mm F2.8 lens
@F=18 and reverse adapter ISO400 1/160s
light with a 1400 lumens 5000K NW flashlight from the side

this LED has a electrical neutral middle thermal pad for DTP stars
The active area is a lot bigger than on he Nichia LED, so it throws less
my LED has a surprizing low forward voltage of 3.46V @0.7A
second Nichia NCSU276A U365
die size 1x1mm
LED forward voltage of my one 3.84V @700mA

Improoved the resulution with a extender
Pictures cropped in full resolution
that is already dedomed from the shipping incident which clemence had, so he got replacements and donated the LED
I can live with as its going into a reflector light
the dust particle got removed later with compressed air
.
The IR Osram LED is hard to photograph as its dome is really high and acting as a very strong lens
