So from what I read its not lumens that are dangerous but rather the amount of light reflected and area of light spot. But I'm wondering how much light is dangerous to the human eye...I come from the world of high power laser pointers. I know that my 445 NM laser can cause permanent blindness at 200mw a square foot looking directly into the laser. So how many lumens is dangerous looking directly into the flashlight at lets say a 25 foot distance.
