Unfortunately I don't have a better example, other than the fact that you can see the dark walkway and grass going all the way back to my red garage. 100 feet isn't that far for a light like the L2D, regardless of what you are trying to light up.
"but if you want to point it at something a hundred feet away and light it up that's not gonna happen"
There weren't any specifics in this statement, like trying to light up a black shirt 100 feet away with stadium lighting shining in your face.
If I have a L2D, and I'm out in the darkness, and I point it at something 100 feet away, be it a bush, deer, dog, etc, it will light it up.
