This whole subject of auto-darkening lenses is a puzzling one.
At the electronic shops every single computer, stereo, tv set, dvd player, digital camera, etc that I have looked at have one thing in common:
A small label that reads "made in China".....or some other asian country where t labour is cheap....regardless of brand.
The CANON camera I recently bought is made in malaysia.
Matter of fact I was recently looking at fork attachments for my bobcat loader and many of them state that frames made locally; forks imported.
I may be wrong but I really think that ALL of the welding helmets have the auto darkening lenses made in china!
and that the only difference between the no-name helmets and the so-called brand name ones is in the shape and headgear...but the lenses are all the same!
where does one turn to find out the truth?
