Well, you can always copy serial numbers that are actually legitimate and laser engrave them onto a fake light. All you need is someone to supply the numbers. You might end up with many lights with the same numbers but why do the Chinese care when they take real Heineken beer bottles along with every other beverage and food product and recycle the real containers fill them with piss and recap them very good I might add and then put them back in their cases and hot glue them shut. Look on YouTube, The only thing Chinese can do is counterfeit everything. Your food, water, beer, cells, lights, clothes, medicine. That is how they work there.
Then you have diversion, mainly in the drug trade of legal pharmaceuticals from India, Pakistan and China. So well counterfeited and even in blister packs, that even Pfizer cannot tell the difference until put into a gas chromatography mass spectrometer.
China makes it’s money copying everyone else’s IP, even their own countries. Pathetic.
