none of the above are genuine cree parts.
Good to know, thank you. It seems that almost all of these OEM chinese flashlights are coming with these fake LEDs, or is it a lottery?
They look identical to the authentic xml’s in the pictures of the very first post of this thread
Going just from the first post pictures, the first one looks like a Latticebright, the second looks to me more like a XM-L, but why somebody would use a XM-L in 2020? Being listed as T6 is very suspicious by itself, an indicator that it’s actually fake.
At this point XM-L belongs to a museum, I see some for sale in KD so maybe CREE still makes them, but they are quite old.
If you prefer zoomies and you can buy from overseas you are better off buying a Wowtac A3S or a Convoy Z1.
None from 999 up are genuine.
A real xm series cree has a larger die
The Cathode sign is a Square, the Anode sign is a Circle.
This is what your photo shows also, there is no reverse of the signs.
Are any large/well known companies using these fake LEDs? Olight, Sofirn, Wurkkos, etc. Or is it only budget lights? Or just budget aftermarket emitters? Sorry, I don’t have much technical knowledge.
I just got This seeknite SK3 from BG
It is advertised as a 6500k xml2 led, however it looks more like a XPG2, or even a counterfeit one.
Any thoughts?
If you pay for them with counterfeit money , does that balance things out ? Sort of like being Cross-eyed and Dyslexic at the same time.
Wellp, if it’s 3.5mm on a side, it’s an XP package, 5.0mm on a side, an XM package.
Just by the looks of the chip, yeah, it looks XP-G2ish.
I wish i was able to sometimes 
Is this a real Cree XHP50.2 3V ?
bought from aliexpress.com/item/4000273314849.html
It just drains 2,8A from a fresh 18650 but ist very bright
“Fake” because at the time this thread was started, many companies just lied and said they were using Cree emitters. It wasn’t an accident, it was just dishonesty. That still happens today, although less often I think.
Got a XHP50.2 light with suspect emitters.
Ceiling bounce test seems legit. Base is yellow. Inner squares touch. But…only one of the corners has a spot, and all the pictures I’ve seen of the XHP50.2 has spots in two corners.
Got any pictures? I've heard that the spot number might vary across different voltage configurations.
NO it doesnt
Just double-checked: the 6-volt version has 2 spots, one round and one square (image taken from djozz test).
The 3-volt version has just 1 square spot (image taken from Convoy AE listing).
Post an image to let us see if the emitter is legitimate.
Is this clear enough?
Took another shot at a macro. This is about as good as I can do with what I have.
Thank you for posting the images. Compared to images of known legitimate XHP's, I could not notice a real difference. If the emitter you have also happens to be 3V, it is likely that the emitter is a genuine 3V XHP50.2.
