Is this the emitter you 2 are thinking of?
Maybe mine is a fake Samsung being marketed as a Cree.
^
I just don't see how my emitter above is the same as that one. The gold stuff in mine is like badly applied gold leaf. Image from Samsung site.
Maybe that’s what happens after it gets hot?
There does look like there is a crack in the silicone dome coating over the gold parts, (on each side in your photo) though it shares many of the features of the Samsung. (including the square corner, the die design, etc.) unless Latticebright or some other copy manufacturer is now even building fakes of Samsung 3535 LEDs.
As paranoia sets in……………… 
There is one good thing about all these fakes though, the uninformed can’t just go out a buy a cheap, great light. You actually have to know what you’re doing. Whether it’s building or just plain buying.
“Oh, you bought that light off the internet? I have one just like it, let me show you mine” 
Banggood has responded to my complaint about the LB ’68 lights that I recieved. First someone responded by email and asked that I send a video! This after I had already sent a picture comparing a CREE Q5 vs their light with the LB. I did not respond to that email, come on, a VIDEO? Really?
A couple of days later another response, this time from someone claiming to be a “professional” asking more intelligent questions. That one I responded to and in a polite manner and “educated” him as to what is going on with the descriptions on their site vs what is actually shipped.
Perhaps we will see some progress concerning these issues.

They are supposed to be very decent leds (but I never tested any)
I have a version from Banggood which I asked to review (to ensure non lattice bright). After burning myself on 10+ of those crap garbage, I am more cautious now. Hopefully, the ‘meco’ one from banggood will be good alternatives!It will arrive in about 2 weeks time.
Just 20 posts ago I wrote about what I got from Banggood. MECO + LB
But don’t blame LatticeBright for all the fakes… The LED in the Meco’s above looks not like all the other LB’s. Latticebright has the phosphor only on the chip same way as the imitated Cree model. The ones with the phosphor all around under the dome could be from another, even worse faker.
I dont think they’re coming out ahead, the lights on Ebay are a lot cheaper than they were a couple years ago. Not sure what they’re paying for leds, but the LB leds cost something, and it’s better to spend $4 more, on the led, if you can sell it for an extra $5
Hopefully someone will photograph the led and ship Crees
I wanted to spend some more time on these micrographs but I had to watch the Steelers win.
No comparisons but the images might still be useful. Plus I just want an excuse to learn more about photomicrography. Excuse all the dust. My Olympus metallurgical microscope is hard to keep clean.
All images are of the same XPL HI that I recieved from Mountain Electornics.
First is my attempt at stacking pictures (I am still learning)
Second is a brightfield image and I contrast that with the flip of a mirror into a darkfield image i.e. no focus or magnification change. What is that vertical line on the right?
Here is one I tried to take with a different light source. (It is quite fun to play with light and what I have been using are different led to light up what ever fits under the objective)
This last one is an extreme closeup. The two marks at the top are specks of dirt stuck to my sensor. Can some explain the orange splatters.
One point of interest is the different look of the bond wires.
Any help would be appreciated.
nice detailed Macro photos of the XP-L HI 
One thing I wanted to add, it’s highly unlikely retailers are aware of selling fake cree leds ….if manufacturers spec this to them, it is this that will be displayed on their website……
They should, however, ask for refund from the manufacturers claiming to sell cree leds when they are not in case disputes arise from customers and stop selling their garbages….
I ordered 5 of the MECO sk68 style lights with “CREE Q5” emitters. I got them quickly enough, problem was they didn’t have CREE emitters but rather the crappy Lattice Bright. When I pointed that out, they apologized and gave me 60 cents credit for each light. They have since removed CREE from their description and lowered the price on their site by 80 cents for each light. LOL
If you have a replacement emitter to swap in, this light does have the 1 mode boost driver for AA compatibility.
MECO light for $2.69
This is good news. Having been burned themselves, BangGood at least, is now aware of the difference.
i did receive a random brand name camo SK68 that had a LB LED from ebay but only paid $2 for it there. Worse tint i ever seen.
Doesn’t explain the orange splatters but this is what came to mind.
I am not certain about FT emitters myself, as i have not bought anything from them in a long time.
