- The Fake-Cree LED Awareness Thread - The new "low" in Budget lights.

I swapped in a real (hopefully) HP70.2
Where do I get a glass lens?

the build quality is definitely not cree.
look at the die attach adhesive.

one indicator of fake is sloppy die attach.
a mature manufacturing process like cree’s wont have that.
that sloppy attach increases thermal resistance.
so far even if the rest of the device looks spot on the poor build quality gives it away.

I don’t know if I should mention this, but I noticed a large influx of Chinese suppliers making “CREE XM/XP family” clones. There are at least three manufacturers I am in contact with are making these.

Make no mistakes, they don’t sell these as “XM-L” or “XP-G” but rather, for example: “5050 5w” (basically using XP-G sized die on XM-L case). It is up to the flashlight makers to advertise these as “CREE”.

You can probably guess what happens when they advertise the “5w 5050” as “XM-L” and push 10w into these.

PS: Some manufacturer I know may offer High CRI version of these too. (although you will most likely get in-spec CRI, but the tint will very much depend on the luck of the draw).

Glued on emitters :person_facepalming: , every time I think I’ve seen everything, this has to be up with batteries filled with sand

To be fair, CREE does this too, but in a less sloppy manner, unless the LED in question are flip-chip ones that can be soldered directly on the substrate.

Are the emitters on kaidomain genuine?

Based on the earlier discussions in this thread, Kaidomain indeed sells genuine emitters. KD also includes the pics of the plastic wrap (with brand, binning and other techincal infos) where the emitters came from for some of the items.

I used this one

What do you think about this supposed XHP70.2 emitter?

Bought here:淘宝网 - 淘!我喜欢

The 6000lm rated by the seller is questionable for sure, and that makes the authenticity of the emitter inside a suspect.

Looks like an attractive flashlight actually, the simple off-low-high user interface sounds great. Led looks convincing and for a 38 dollar flashlight also not unlikely, but you never know.

My doubts are on the holes position. In the original CREE XHP70.2 datasheet, holes are reversed. Seller told me there are minimal differences between bin codes.


But the - and + are correctly connected, it could simply be a horizontally flipped photograph, happens a lot on websites.

Photo is mine. LED is showed same as real.

thank you for your sharing

Not exactly a “fake” Cree because it was never mentioned as “Cree” LED…

The Sofirn SF34-11T comes with 11 of these LEDs, which the description says are “XK” LEDs.
Any idea what they might be?
(pardon my not-too-clear pictures, my camera is not good at macro shots)

This one is obviously a LatticeBright. Most likely XK-6W model (hence the “XK” probably means the XK-series). It’s more or less XP-G (with probably worse implementation) in XM-L footprint.

Someone sent me of the LED in a cheap flashlight he got, asked me what may be the specs.

It doesn’t look like any of the better brand LEDs, so it has to be a clone. Any idea what clone this could be?

Another unknown (for me at least) copy of XM-L2. Note sign LMP in left bottom corner. I’ve got one picture from friend and make another myself found in cheapo tripple led bicycle light. Has anyone seen that before?
