Minimum lumens to impare an intruder?

The muzzle flash from a 12 gauge is usually enough to blind so how many lumens is that?

on my night stand beside the clock radio is both my modded SRK Kung, and a Modded BTU Shocker. On the dresser is the Olight SR90 Gun-light with a 200mw Green Laser & modded SK98 mounted to it.
Do those count ?

10kW pulsed laser?

I agree it’s all about the intensity of the light rather than the total output, a MiniMax might have 5000 lumens, but it has less than 20kcd. It’s around the same brightness as a skyray king if you pointed both of them at your eyes.

100kcd+ is definitely a safe bet for someone with night adjusted eyes I think.

100kcd is more than enough. 50kcd is very blinding when it’s pointed right at you.

I’m saying this is because you also want the beam size to be reasonably big. Sure you can get dedomed XPE2 to go 100kcd easy, but how to aim it steady to the intruder’s eye with the tiny dot? XML2 at 50kcd is much easier to aim and more effective.

I was thinking of a 9mm flash, but .45 would only be better. A .357 from a 2” barrel would be a little too bright.

PEW PEW PEW :smiley:

I think strobe is a bad idea. It disorientates everyone in the room. I know this because when I go to dance parties and the strobe is on, everyone bumps into each other in a comical fashion.

It doesn’t matter the lumens, but the luxes.

You can have 100 lumens (total amount of light) but if you have a really good throw, you can put all those lumens in the eyes of the “bad guy” and disorientate him.

Lumen a measure of the total amount of light emited by a source (luminous flux). Lux is the intensity of that light at a given point (illuminance). lx = lm /m2

The eye takes time to adapt to light, if it’s pitch dark, and you light up all the room with a 1000 lumens light, you will be both impared. You need to have a good deep reflector (or aspheric) thrower to create contrast. The high amount of light in his face will close his pupils (but not yours), and kill his adapted vision.

To have a comparison, between 30.000 and 100.000 luxes is the same than looking right into the sun.

Find the best thrower you can. And also remember that if he has a gun and goes blind, he may start shooting all over the place, so take care.

Or at that big ol’ sun he just got socked in the puss by…which just so happens to be IN YOUR HAND!

So which technique do you think might be a good idea to start practicing?

@WarHawk-AVG I corrected a few physic concepts from my original post)

Dude, I don’t know about where you live but here the sun register 100 THOUSAND lux on the ground.

:slight_smile:

Hahahah sorry, I meant KILOluxes :stuck_out_tongue:

I’ve always wanted someone to come at me when I’m on a night walk with my TK75, the fast strobe on that is insane, then I’d just clock em with it (hopefully wouldn’t damage my baby)

Silly, you strobe with the TK75, then clock with the 6D Maglite. That's what they're made for.

Point to Gj

Last July 4th we had an extremely impaired bad guy kick in our front door. Let me tell you from personal experience no you don’t. You absolutely do not want someone coming at you trying to cause you/your family harm no matter how well you think your prepared. To say so is just silly… Even cops don want that. It’s no fun.

As for what I found best in our actual situation (not just guessing/testing on friends family). I had a 700Lm P60 mounted on my carbine and it did almost nothing to slow/stop the BG, what actually did help, and changed my entire outlook was my wife with her hand gun and a nitecore EA4 in strobe, that really made a difference. I’m not going to go into the whole story, its long and honestly I just don’t feel like telling here it but after that night I changed my carbine (an AR) mounted light to one with instant access to high and strobe (at first I was using a quark tactical but I’ve now got a custom programmed driver in a balder SE2- single clicks more than .5sec apart just turn it on and off, a sub .5sec double click enters strobe). It took a long time to get the FW just right (Richard helped) cause the way I’ve always trained momentary operation is very important to how I use my carbine, I don’t want it entering strobe when I’m just trying to turn it on and off quickly. The way it works is almost identical to how streamlight makes their dedicated weapons lights.

Holy crap C_k! Glad you’re still around to tell the tale! :open_mouth:

My TK61vn,has about 1700 lumens but the PBI is 622Kcd!!!

Guaranteed that “Hot Spot” will blind anyone or anything,not always about the lumens!

Also,my X10vn is about 1000 OTF lumens w/ 95Kcd,that is certainly sufficient enough to blind someone! I accidentally [did not see them] blinded some fisherman along a bank from about 75 yards away w/ that little power booster torch!

There are numerous others as I am sure others could mention as well!

I mentioned my most powerful modded thrower and least powerful one…….least is not a good word! All the ones in between will also do the job!

Wow man, I’m glad you and your family are okay
