My buddy was showing off his new 250 lumen light. After sitting in the dark for a few minutes inside he turned it on pointed towards the ceiling. Later he turned it on outside and the beam carried pretty damn far. A few things happened that we observed.
A. There was an uncomfoetable adjustment moment when the light was turned on inside. B. None of us could see a damn thing after it was turned back off. C. There was no mistaking where the light source was originating outside. D. Again there was temporary adjustment when the light was turned back off. Not near as bad as inside, but I do question strobing outside a bit more with that much power. The brightest light I have is 65 lumens. I personally think 250 lumens is too much for home defense now. If you strobe one room and temporarily need to adjust, what happens when you can't see the guy down the hallway? So I'm looking at the Inforce WML. Is 125 lumens going to over do it? I really don't have a median for comparison. I just know that 250 lumens seems like a liability and 65 lumens really isn't enough. |

Lumens are a measure of all of the light coming out, not just in the center. 700 spread out lumens can affect your eyes less than 100 concentrated lumens, depending on the light source, how far away it is, and where you are looking. Think of an incandescent light bulb vs a focused flashlight hitting you right in the eyes. Even 20 lumens sucks if it is all going into your night adjusted eyes.
It all depends on the light's setup of the LED and reflector/optic. A better number to look at might be lux, if the manufacturer gives that information. Beam distance will be a good indication of how concentrated it is if they do not list lux. |

I have a surefire M961 with a 450L bulb in it for my outdoor carbine. I can shoot with my 6-18X scope out to 100 easily in pitch black. For indoors it would be too much. |
