So, is the above fake XML-T6 a LatticeBright or a LB clone?
Have another one to help identify:
This is from an UltraFire UK68, supposedly Cree Q5 LED:
(pardon again, it’s very tiny and my camera is having a hard time focusing on it… )
(The glass/dome seems to look quite dirty from the pic…)
Yes definitely likely a litticebright low quality knock off of a Cree.
Fake XP-E
Possibly LB
Problems with OP photos
I will work on fixing that this weekend. (the photobucket change screwed over all of us)
There’s no hurry
It was just to warn
A friend wanted to know how to recognize a fake
Hi.
I bought a cheap light at a local store and for the fun of it, I took a look at the led to check if it was cree or fake. I’m unable to see the pictures in the OP, and even haven gone though all the post in this thread, I’m unable to know exactly what to look for. The soldering looks to be round, indicating it to be cree however the print+led isn’t ‘waved’ (in lack of a better word) indicating it to be fake? The print itself doesnt state CREE but BG so I assume it is a fake. I would just like to be able to tell it just by looking at the led itself.
Thanks!
Edit:
I took a different light I had laying around and did the same on that. The led looks almost the same (round solderings, no waved print/dome) but the print looks nicer. Dont know that to make of it. Anyone ?
Fake for me
The core is too small
Bad fakes
The real ones have bigger die and ESD protective device
Thanks! I really appreciate it.
I just took another pictures of another light I have (Nitefigter bt20). The core is much larger than the others but still no esd wire. The ‘waved’ dome/print I mentioned before is there. To me it looks a lot like the model photo in the last post.
Whats your opinion ?
The ESD wire is not seen if you look from above, on an angle you can see it or from the side
This LED looks like a real Cree, at the opposite side of the bond wires you have near the die corners 2 sqaured dots
Definite fakes. I will fix the OP immages asap, ( they went bad do to the photobucket mess)
Sorry for spamming, but I have an ongoing argument for this one. Can you please post your view on this led?
I think that’s a Lattice Bright XM-L clone. In the real Cree XM-L pics that I’ve seen, the diagonal corners of the yellow square is almost the same as the diameter of the dome.
That looks like a fake. ( Latticebright possibly.
A representative for Cree has stated that there is a high probability that this is a genuine Cree led. He was ofc not able to state this with 100% certainty based on the picture alone, but still… I was of the belief that is was easily a fake copy.
The one in post #908 above is definitely a fake. (Latticebright) The die is way to small to be a real XM-L, and square bond wire pads are visible.
I’m inclined to agree, but the direct quote from the Cree representative was “It looks like a Cree XML generation 1 high probability but it’s impossible to be 100% certain.”.
Oh the horror, if Cree themselves believes the fakes are genuine.
Just wondering, this is supposed to be XM-L2, but would like to ask if that’s genuine or a fake? (or the image is unclear…)
Today I got a Revtronic F30B flashlight, with this LED inside:
This is definitely not a genuine XM-L2. I'm not sure about the manufacturer and the type, but I'll test this LED in the next days to get the efficiency at binning conditions (350 or 700 mA 25 °C Tsp).
Nevertheless, the tint is surprisingly good and a clear white (approx 6000 K) without much color in it. But in this case it means also that the presence of the counterfeit LED can no longer be determined at the tint only.
