The 1840 features externally-controlled continuously variable 9 -13 shade control for quick changes without helmet removal. The 2450 series features a protected internal continuously variable 9 -13 shade control. Variable sensitivity and variable delay allows the user to adjust the time required to bring the helmet from a darkened view back to the light state. Both helmets also include an integrated grind control, which fixes the lens shade at 3.5 in. to allow the user to wear the helmet as a grinding shield.
Both series are solar-powered, with the 2450 series featuring user replaceable batteries. In addition, all VIKING helmets include extra inside and outside cover lenses, a bandana and a sport-pak style helmet bag. All VIKING helmets also are magnifying cheater lens and hard hat adapter capable.
