Definitely look like latticebright counterfeit LEDs to me.
Yes they’re indeed “fake” XMLs, still pretty bright though.
FmC, I did direct ground wire like you mentioned, and the brightness was exactly the same. It does seems like it’s running on higher current than 1A because of extreme heat produced by it, but also consider the number of LEDs and lack of proper heat sinking. Unfortunately I do not have another can-style light to compare the reading to. Maybe I’m not doing it correctly.
Here’s some beamshots - fake SRK on the left, real TrustFire with 3 XML-U2 on the right. Pics taken during daytime on a cellphone camera 4ft away from the wall. They look very similar when turned on, but then SRK starts dimming rapidly to about 70% of original brightness.
