I never heard any counterfeit Cree LED. These LED are precision light and produced in masse. The counterfeiters don't even bother copying these LED's
Yes, they are counterfeited.
Source?
.... our manufacturer literally asks us if we want to use the real CREE diode or if we want to use the cheaper domestically manufactured imitation diode.
First pic is real, second one is fake. Both were sold as "authentic XML-T6".
I have never seen nor heard of fake cree XM-L LEDs before.
Whose to say your manufacturer has any idea whether or not these supposed 'fake' XML leds are indeed as unauthentic as they claim?
If you are referring to the images you linked to then the only difference is the first led is an xm-l2 whereas the 2nd image is the older generation XM-L. The xm-l2 has a silver substrate whereas the XM-L has a green substrate. Among other differing physical characteristics such as two bond wires as opposed to three.
Indeed the newer generation XM-L2 LEDs have a higher luminous flux compared to the older generation XM-L, but there is nothing unauthentic about the XM-L led in the OP nor in the image you linked.
Genuine Cree XM-L led.
Genuine Cree XM-L2 led.
^^^and you are an idiot. Cree makes many variations in various footprints. In the XM footprint, the green ones are XM-L while silvee is XM-L2. The bin doesnt change the die color
Yet another case of an "industry expert" that only knows what he was told and takes it for the truth. Although cree is a US based company out of NC, they started pushing manufacturing over to china in 2010.
Haha, looks like you can't deal with the fact that all those shitty flashlights you bought don't have real CREEs in them. Convoy is another brand locally known for using imitation diodes.
I am done here, conclude what you want from my information. Just thought I would share :thanks:
