I went to my kitchen in the middle of night turned on the lights, and then when I left I turned them off and my "night vision" was ruined. Couple minutes later I thought I should go compare that effect with my 500 lumen Surefire, and what do you know it has the same effect as my kitchen light which is way dimmer. I don't get why people say 500 lumens is too much for indoors?  Their eyes can't be worse than mine. |

I've shined my Fenix TA21 at ~225 lumens inside after waking up in the middle of the night. It blinded me.
I like high lumen lights but I think more definitely isn't better for a home defense light. Sometimes I think if I heard a noise I'd just wake up, temporarily flash my light so I can start adjusting, then use it on full brightness anyway. Just go ahead and ruin my night vision from the beginning. I'd have the advantage of knowing the layout of my house. |

Reported for racist comment.
(Jk) The only time my 500 lumen x300u has been "too" bright is when I light up a door frame 2" from the muzzle or stand square to a mirror. To say it dominates compared to what previously seemed like a bright x300 is a major understatement. Posted Via AR15.Com Mobile |

Their eyes can't be worse than mine, and I'm Asian.lol   ........Wait can I even say that?
Are you inscrutable?

Quoted: IMO, if you know your light is very bright and you blind yourself with it it is an error on your part, not a fault of the light. I figure, if Im in my own house the light comes on and stays on. Its not like you can hide. |

Its not like you can hide. It's error on your part? It's how the eyes work when they're dark adapted and confronted with a bright light. There's nothing you can do to avoid your eyes switching from relying on rods to relying on cones when there's a sudden increase in available light. |

Is there no way at all you can keep it under control so as to not point it directly at close objects? Point it directly at a white wall that is close to you will get you flashed. Having it at low ready will still let you see but the same wall will not blind you.

I really think you don't understand the concept of night vision or illumination. Returning photons (light) to your eyes will force you to lose night vision and temporarily blind you as your eyes adjust. If you're illuminating something -- no matter how close or how far -- you're bouncing photons off that object and returning them to your eyes. That's the whole point of having a flashlight. That will cause you to lose your night vision. |

The blindness effect is from lux, a result of candela or beam intensity. Lumen output does have a correlation with lux and candela as the light has to be driven in some way.
The blindness effect can happen from a 200 lumen light as well. Having textured reflectors help reduce this effect, as the beam is diffused from a focused hotspot. |

The OP should have someone print out some good guy/dad guy pictures , dark adjust his eyes then turn loose 500 lumens on them from across the kitchen and see how fast he can identify the bad guys.
Going from dark to 500 lumens of beam would be even worse than dark>>>>room lighting>>>>>>500 lumen beam. |
