Surefire clone, how to tell??

[fromfallouttodust]

As the title states, how can you distinguish from a clone to the real thing?

Looking at the surefire website, there should be a QR code and some text printed in white on the top of the main body that gets pushed up against the rail. Mine's the XP model but the unit should also have a strobe feature if you press the tempery on switch fast.
