How about a 4D incan maglite?
After you whack the intruder on the head with it, he’ll be quite stunned!
NiWalker Nova MiniMax MM15 would do it
The best way to disorientate would be with a fast strobe of about 3,000 to 5,000 lumens. It's bright enough that the person's eyes cannot look anywhere close to it and the fast strobe will keep the eyes from adjusting to the light. You may get just a few seconds advantage that way, before the person just starts shooting blindly your way. I would think something that was a little more floody would be better, so you don't have to try to put a small spot directly on someone at close range, since it would be hard to follow a moving target.
Best would be a flash bang, but probably illegal most everywhere.
Remember to wear sunglasses.
Heard a Spec Ops (Navy Seals) guy told a buddy of mine they look for a min of 600 lumens on strobe to temporarily disorient someone, allowing them time to subdue the person. I assume that's in close proximity for their usage.
This is why you want a quick access to a strobe mode if you believe in strobe mode for defensive purposes. I prefer quick strobe access this way, otherwise if it takes 3 secs or 6 clicks to get there, may be too late.
I think it's more about kcd (or actually lux at eye level). 600lm of normal flashlight beam might be enough, but 600lm of light bulb would not.
That being said, I'd use a >100kcd light. (either a thrower like K40, just hoping to aim well enough - or opting to use X60 which doesn't require so good aim - on strobe of course)
:D
I think you only need .45 lead lumens :bigsmile:
Do they measure lumens in grains?
230 grains should do it 
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 ?
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.

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?

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