I know the coating on the Fenix is probably less thick than others, but LedMuseum has tried his scratch test and mentioned that it was HAIII.
I wonder if you have tried the same on the outside of the light. I know it doesn't make sense, but the I scratched the inside with increasing amounts of force until i made a mark, and then tried it outside, and up to that point at least, it did not leave any gouge on the HA (though it did leave a sort of smudge mark).
another question would be how much force would you consider necessary to test whether it is HAIII or not? it would probably depend in part to the thickness of the anodizing, but a thin layer of type III anodize is still a type III anodize right? it just wouldn't hold up to the more forceful attempts at scratching it because what is underneath is still soft aluminium...
anyway, i'm inclined to believe that there is some sort of HAIII on the Fenix, as it does withstand light to light-moderate scratches from my swiss army knife, but it probably is just a very thin layer of it... does that make any sense?
