That's a cute little driver. It's like and itty bitty controller case
I tried to remove the front of the light to get to the driver/emitters and I couldn't crack it for the life of me. It appears to be glued with the toughest substance known to man and I started scratch up and deform the case wrestling with it in my vice. I'll try again later with some leverage - a multigrip pipe wrench type thing.
In the mean time I accidently fed it 12v while testing (power supply reset to default) and it didnt pop so I guess the driver can take that. That's handy if nothing else for running it off my main 12v DC-DC converter. Light output was slightly brighter with wattage climbing to 18w
Of interest at this voltage even when turned off the driver seemed to allow some voltage 'leak' and the leds glowed very dully. This allowed me to very clearly see the distinct shape of the emitter, which was square (obviously) but with 2 little cut outs on one edge. I'm not sure if that's a useful identifying it.
Otherwise visually this is what the emitters look like. It's not the best pic (taken with my phone) but you can clearly see the 3 wire attachment.
That is consistent with the XML appearance based on THIS
reference image - vs the XPGs which seem to have 2 distinct wires at the top and bottom.
So yeah, maybe they are legit ? In which case out with the lame driver and pump up the volume
