BEST ANSWER RIGHT THERE>>>> THE Harbor freight, Northern Tool, and even some of the Early Snap'on helmets were all from same plant in CHINA. Some lasted a decent amount of time. THEY advertise that its a minimum shade 3 in static state and goes up to a 12. HOWEVER they do not pass the rigourous inspections for safety as do a SPEEDGLASS(3M), OPTREL (SWISS MADE), or a Huntsman/Jackson now owned by KIMBERLY CLARK. All huge SAFETY CORPORATIONS. When you buy a helmet for occasional use in the garage they are find cause the chinese lenses are 1/15000 of a second flash time which means. you have to flash your eyes 15000 times to equal 1 full second of arc flash to your eyes. NOW, THE SPEEDGLASS, OPTREL, and JACKSON.. 1/32000 How many times are you on and off that button, and what are your eyes worth. Id spend the money and buy the good one but I like my eyes.
