Any light having a somewhat wide cone will be much brighter in the center than in the peripheral area. So yeah, there's a way to light things up differently.
That being said, I don't quite get all the fuss about this; I don't really know but I don't see a small tac light having enough power to actually blind someone, even temporarily. Incomodate, annoy, making them see spots for a few seconds, yes. But blind? I'm skeptical about this. It's not like they can pack the equivalent of a 1100W High Pressure Sodium bulb at 150L/W.... Yes I'm exaggerating a bit but you get the idea.
PS: I know that some post I make like this can look like I'm acting as a know-it-all or that I'm stating facts or whatever but it's not the case here. I'm really questioning ( as in having questions?) this here and if anyone have actual scientific facts I'd be glad to read them
