The first two are very fake, not even Latticebright, the last one may very well be a Cree XP-E.
I can’t tell about the Q5.
The first one, supposed to be XM-L2, is a clone of the original XM-L emitter, not the newer gen model.
The second one; I found one of those in a light of mine; odd with the phosphor “overspray” that surrounds the die.
Here’s mine, from a couple of pages back, shows the same overspray on the phosphor layer:
The first and second seem the same type LED, just that the second is made poorly with the strange corner where the die seems folded.
The first two are definitely not CREE, the second one even look worse than the Latticebright fakes, as i notice the phosphor has been over sprayed on the bond wires and the substrate around the die.
OK two new SRKs arrived
And these are different, interesting look the hardly readable webaddress on the LED shelf.
What does it say?

The second one made the first sequence more clear, but the last figures were wiped here, so I tried

and choose searchterm:

That got me to this page

translate to English, seems flashlight company
another hit, same company
http://gcj72785959.cn.gongchang.com/product/?gct=3.10.1-2-2-1.3
and there it is, a SRK section!
So the manufacter of these SRKs seems to be this company.
Oh well, maybe I am wrong and somebody knows Chinese or the company. I wanted to share this anyway.
Also, the LEDs used.
They look more like the LatticeBright to me.
And from the other
Those definitely are the inferior Latticebright leds. Also no heat dissipation with the thin aluminum star-plate and shelf-less body of a bad SRK clone with no heatsink. I would file a clam back for that crap.
By chance I came across an item listed as a cree emitter but based on the photo is actually a latticebright. The seller? Banggood’s US warehouse.
$7.52 for a latticebright on a 20mm aluminum star?
Tss the pics actually show LB
oh wow… now Banggood is actually selling Latticebright trash LEDs “Listed” as Cree LEDs for Cree Prices? This is a new RED flag for Banggood. LB LEDs are not worth .52 cents let alone almost 8 bucks. 
Someone above commented about Fasttech SK98s with LatticeBright emitters
In their “New” products list they have various kinds of camouflage SK98s
(new! Even harder to find if you drop it outdoors …)
And, clever, each one gets a separate questions/review page so any inquiry about what “Authentic/Cree” means in English shows up only for one of their many versions of the light.
The days of getting these types of budget lights that come with real Cree LEDs are dissapearing quickly.
They don’t even try to hide it! It’s an obvious LB emitter with the branding PRINTED ON THE BOARD!
At least whoever is soldering the LEDs to the stars is honest!
I see an email address. @126.com

the “126.com” domain name is seen a lot on billboards across China.
Well bugger. I’ve been duped. Luckily it was only a $NZ4 torch.
Just looked under the hood of a cheap wee single 18650 ultrafire tube light I got 2(?) years or so ago. Found in a draw, took lens and wee reflector out. I see LB on the star. Was meant to be a Cree Q5.
No wonder the beam is a bloody awful washed out purple / white.
I will only buy from America now. And reputable sources. This fake Cree saga sucks.
Anyone know if there are fake XPL-HI chips circulating ?
A bit worried about my KD C8 en route.
Is there any thread that compares the fake LB Led with the real Cree ones?
No, I'm not tellin' ya..... 
This one !! Look Back to the very first few posts.
I’d be interested to see them tested side by side with what they clone, its all about the lumens per watt 
Lattice Bright now has a 4 die chip. They call it the “HP50” :Sp

Check out their web pages, they also now have an “XL” among others
