Mine is the one Miller threw in with the welder when I bought it. Looks like regular sunglasses tint when your not welding. I like mine. I had trouble with it not darkening once awhile back. I set it out in the sun for a couple hours (Solar battery) and it's worked fine since. The only downside, if there is an obstruction between the arc and the sensor on the helmet to block the arc light you can get a flash.
