klrman, the main problem with “fake” leds is not that much related to their lumen output, which may just be hardly noticeably lower, or even good. The main issue is with regards to the quality of their spectral power distribution curves which tend to qualify like straight Jenkem.
Nice demonstrative video about this topic:
I already find standard CRI brand name leds shitey enough, so go figure.
Cheers ^:)
Barkuti, thank you, that was a really good video! I've never heard of that brand before, but I have a few 100W LED work lights in my garage and would love to change the emitter to those 5600k ones! In fact, I will try and get a hold of a few and give it a try. I'm sure if the watts are the same, that the driver would work.
Does the pic of my T6 look like it's not a Cree to you? I think I'm right but it would be good if someone with much more experience would confirm that! Also, would you or anyone know who sells legit XM-L2 T6's with a board? I want to upgrade my flashlights if I can get my hands on the real thing.
Looks fake to me! To buy genuine emitters, Mountain here in the US is preferred source. So far, FastTech has been a good source for genuine Cree emitters as well.
Thought it was fake! Thank you for the links too, just what I needed

Is this a good one, or a knockoff?
Clearly not a Cree LED.

Read how easy it is to reflow solder a led and get a good LED that is not fake
Bought 4 of the Warsun CT9T on sale on AliExpress for $8.51 each. They all have LatticeBright emitters and they don’t have the tail switch like the older models. Only side switch on new ones, old ones have both tail and side switches. Older CT9T’s had Cree XML2.
Looks like a real Cree XP-E to me.
Or am i missing something?
I bought a Warsun CT9T from Banggood for $14. It was a huge disappointment because I had read a few reviews. It was about 600 lumens tops, thin cheesy build. I sold it for $10 value with another deal.
Pretty sure the LED was counterfeit. Banggood refunded me.
Yeap, the 3rd lead.
Aha, indeed. :+1:
Falke led cree xm-l2 buy at gearbest

I want to order this just to blow it up on the test bench for some reason….
yes, Looks Lattice Bright XM.
Cold light, a little blue :person_facepalming:
That fake XM-L2 from Gearbest is a new level of lying to customers. It handles about a bare emitter, the description mentions ‘Cree XM-L2’ and the tell-tale dotpattern is not shown in the pictures (the clear picture above is jorge’s own picture). 100% deception of customers!
Shame on Gearbest!
I happened to buy that item some time ago and the holes are arranged in diagonal and the connection to the small wires are round as far as i can tell on the one i got. Somewhere in the supply chain somebody must have switched suppliers afterwards to a cheaper one, Gearbest may not know they are selling a fake xm-l2.
The difference is very subtle, if you are not looking for it you would not find it.
For most people, square yellow thing that doesn’t look like a 5mm led = Cree.
