Perhaps that's true jur, but I'm not totally convinced. I held both LEDs in my hand, side-by-side, and they were similar, but not the same. Maybe the knockoffs were old Lumileds stock, sold to some Chinese manufacturer for cheap. That manufacturer certainly didn't take very good care of them though, because all of the lenses (which were clear as water on the replacements) were scratched and cloudy.
In either case, the warning still stands; if you buy a cheap Chinese knockoff flashlight, expect to get 'seconds' in terms of quality.
