i think i got one of the new tlr1s' theoretically rated at 300 lumens and i will tell you its about the upper limit for operating in my house between mirrors, white walls, white tiles in the bathroom it defiantly washes out my night vision (not nv just eyes used to darkness)
and it will easily overpower my trijicon rmr if the room is dark and i just turn the light on with no ambiant light to make the auto rmr ramp up a little
so here is my question for running in your house/ tight confined spaces eg car where you might hit the light while presenting on a threat with your window up which do you prefer ultra or regular x300
another fairly nice thing is if i can id a threat i dont have to apply holdover on my tsd combat systems rmr g19 frankengun ~60-80 yds till a 9 starts really dropping off
This is why I hate ACOG's, RMR's, and anything else that's not an Eotech, Aimpoint, or S&B Shortdot equivalent. They suck at night, and you will quickly learn to hate them in the day-time in some situations.
That said, I have yet to encounter a light that is too bright to use indoors. Even 80 lumens in a mirror will blind you, just be aware of your surroundings. I have white walls and a few shiny things, too. No issue.
I like extra juice for outdoors, as my lights are mounted on a rifle and an SBR. For a pistol, I am a fan of the hand-held because IWB holsters + lights don't mix so well for me.
Currently I am running a P60 400 lumen drop-in on my M4 and a M300A (soon going to test out the M31 XP-G2/VME). I would love to run the EB1/M600 Ultra combo, but it's not out yet.
