**Please be aware, this is the helmet shell only, it does not come with the Auto Darkening System**
 
The Optrel Crystal 2.0 auto-darkening welding hood features shade 2.0 light state that is unmatched in the world for color and clarity. The Crystal 2.0 lens has fully automatic shade 4 to 12 arc brightness detection with Twilight feature to gradually bring the lens back into light state from welding state, reducing eye strain. Optrel's Autopilot automatically adjusts the shade level based on the brightness of the arc or flame. The auto-dark lens can also be operated in fully manual mode with infinite shade adjustment between shades 4 and 12 for a custom view of the arc.
 
The Crystal 2.0 welding helmet also has improved True Color technology, which allows for realistic color perception in light or dark states. It scores a perfect 1 rating for optical class, scattered light, homogeneity and angular dependence. The Crystal 2.0 has external controls to switch quickly and easily from weld to grind mode and back again. Delay and sensitivity can also be controlled using the external knobs.
