Are laser power ratings for lights universal around the world,probably not?

I am curious as to the ratings system of laser power in lights and it seems like each country has a different ‘standard’.
I had inquired to one of the LEP light makers in China as to what class of laser they use in their light and I was told it was a Class 2….so being in Canada that would probably equate to maybe a Class 3 or 4? I think a laser cat toy from the Dollar Store is a Class 2 over here. Thanks

Anyone knows where to get a >1W blue/violet laser rated “2mW” or similar, let me know. :laughing:
