sadly most of the cheap “T6” or “**fire” lights we see on Ebay and many of the Chinese sellers these days will have a fake or CREE clone such as the latticebright leds. Only the established Brands and reputable sellers will have real Cree emitters, (Such as Convoy, Thorfire, Manker, Thrunite, Nitecore, Olight, Foursdevens, etc. or any of the BLF special editions like the A6 are the best bang for the buck lights.
I just recieved a flashlight with a fake XML, that looks like the “Unknown” led. I would say it makes 400-500 Lm Max, I might be wrong, For the size/output of the led chip I’m pretty disapointed compared with a fake XP-E of a Skywolfeye that I have.
I’m interested in knowing some sepcs of my led, mostly how many Watts it draws. Is there any info/tests?
The flashlight name is an “Elfeland 236”, it’s the typical chinese thick flashlight, with zoom, that supports 26500 batteries.
looks like a normal XM-L fake, I ran a test on one of these in my sig to get an idea what it can do. I was actually surprised what it could handle when reflowed onto a copper DTP star. Although if you are doing that, just get a better LED.
Do you have an idea of how much current/watts it uses, as is?
Look at the chart in the thread and compare it to the current readings for the flashlight. It is impossible to know what kind of current it is seeing. Although most are not driven very well at all. Generally you get 300-400lumens out of them in a light like that depending on the battery used.
May be Lattice Bright XL or XK

Whats the difference between these two LEDs? I can not find a difference.
I have not found differences either
Possibly none
It is not a LatticeBright because the dot in the corner on mine is round, on the latticebright is square; furthermore the cut of the white board on mine have like a pattern, lattice have a straight cut just like Crees.
It seems than even LB clones are too expensive for chinese flashlights these days… so I guess they sourced an even cheaper LED from an OEM manufacturer that clones the clones

I’ve done some current test, and they explain what I saw. My multimeter is not too good so it may be a little inaccurate but at least the results are good for comparison.
With a 3.85v battery: my XP-E draws 460mAh, and the “XML” 640mAh and 330mAh at medium, which makes sense because the brightness at “medium” is similar to the XP-E “high” and it should be since the XML is much larger and should be more efficient. And I did not see much difference in lumens when using 3xAAA (520mAh). That puts the XML at 2.64W, let’s say it’s 3W, it’s pretty low.
I would blame the driver for this.
PD: With the battery charged to 4.08v, XP-E: 580mAh, which makes total sense, it agrees with other reviews and it means that my multimeter works well. For 4.14v the XML 770mAh, it’s better, and outputs a decent amount for lumens for the watts used, but I believe that could be much more powerfull, but it’s ok.
I will not do more testing.
Fake XM-L2 found in a Supwildfire thrower.
Argh. How else can they make it cheaper? I suppose they can fiddle with the phosphor mix. That would change the emitted spectrum.
looks more like an sst-40 fake to me.
The above post is misplaced in this thread and close to commercial spam, but the pictures are nice 
Dear bhvm, there is a thread for car headlights, you may get response for your bulbs there:
Link: The BLF Automotive Car LED headlights, results, opinions and beamshots!
Dear DJ,
This thread is about Genuine/Fake Cree LEDs so I am giving you some brain food to think on. Its not commercial.
BTW these are not MY bulbs. I am just the reviewer. And my reviews aren’t sponsored crap. It would help to go through the entire thread in above links as I am comparing this bulb to few others. Hence the Explanation TEXT on pics.
It’s about fakes actually.
But welcome to BLF.
Then I’m mistaken, and sorry about that. I did follow your link and your posts in that automotive forum suggested that you are enthousiastic about the product but also related to the brand. I did not say that your reviews are crap, I just assumed a relationship to the brand. There’s many reviews here on BLF of which the writers are are in various grades related to the sellers of the products they are reviewing, but many are still quality reviews (BLF may be a bit special in that aspect).
My suggestion posting in the car headlight thread was well-meant by the way, I think it is a good idea
1. Sure I would like to take your idea forward and participate more on BLF. I have completed research with some of the Top research teams with respect to LED tints (CCT, CRI, Warm on Dim, Dual tone etc).
2. Am also quite interested in knowing how my posts ended up sounding ‘Brand affiliated’ so I may mend that. Because I purchase all my review units by hard earned cash. Absolutely no Brand patroning. However I also do not step back from suggesting which brands worked well with me and which did’nt. So that many people may follow my purchases.
3. My Specialty is that I keep updating my reviews 2~5~7 years long. I do have some long term data on (limited) products. Feel free to drop me a query on that.
Have a nice day!
Does anyone knows if Coast uses a real/fake LED? I have a hp7 and looking at the hp17, 970 lumens and hp14, 629 lumens.
