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

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.

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.

My LED tests: Cree SC5 based LEDs (WIP!)  ---  Nichia 319AT 83 CRI - Optisolis (3000/5000 K) - Lumileds Luxeon LXML-PWD9 - Luxeon MZ 5700 K (90 CRI, 3 V) - Luxeon V (CSP) 4000 K 70CRI - Luminus SST-40-W (+ dedomed) - Cree XP-L2 (+ High CRI variant) - XHP35 HI - XHP70.2 - CXA1304 COB - OSRAM OSLON Black Flat HWQP - SYNIOS DMLQ31.SGLE UW Q8WP - unknown 5050 LED ---- finished: JAXMAN M8 (Mini C8) HighCRI Triple

Test of the in previous post shown unknown LED is now available, with very interesting and surprising results!

The one in the 1st photo looks like genuine CREE XM-L2 (99%) but the one in the 2nd photo is fake XP-E(100%)

It misses the third ESD wire at the side and the brown area around the bond wires on the die looks unfamiliar too.

My verdict: fake

Bummer… This emitter is from a flashlight model that was vetted by the community here at BLF as genuine XP-E in the past, so I guess either the whole product is a clone, or the manufacturer started using fake emitters.

Many thanks for the help guys.

SingFire SF-348.
I posted a new thread here asking for suggestions on flashlights with similar specs but a real CREE emitter.

If its a genuine SF-348 it should be a real Cree XP-E. (i have not seen one up close to have a look at the LED, as all i have is the BLF special edition ones with the Nichia 219 emitters in them. Maybe another member may be able to chime in on that one.

It does look like a Latticebright XM2, (their copy of theXM-L2) I have a light with one in it and it has the same more-pronounced surface dots as the ones in your photo does. Though this version of the LB copy seems to be a bit better tinted than their fake copies of the XM-L, XP-G, XP-E emitters.

Cree never made XM-L2 emitters where there was phosphor on the bond wires & contacts like in that topic. (that looks even like a fake Latticbright fake with a very sloppy phosphor coating mess.
