If you have a plan for stopping him, and the weapon to do it, then blinding/disorienting an attacker for 2 or 4 seconds makes sense, other than that, then no.
A rough guy will flinch and then recover, to go back to finishing his crime, unless you use those seconds to end the crime.
It wouldn’t be very clever of car manufacturer’s if that was possible.
Car headlights are dipped and you don’t get close enough in the direct beam of the light.
A strong light pointed directly in the eye would temporarily make it difficult to see objects clearly,but do you want to hang around to give it a go or just simply get out of there as quick as possible?
It’s just a theory - personally I think that blinding attacker with let’s say 500lumens should give a second to kick his balls or perform other type of defense. While blinded it’s much more difficult to see and block what’s incoming.
Blinding and running away - I can’t imagine how it could work.
A green or blue laser, in the range of a couple of watts? 
i got 3 of those lol- though i dont wanna do that unless i have too
Yes , a correctly powered 445nm flashing in someones’ eyes would really be blinding !
With the violet/blue spots swirling around even in their closed eyes after a jolt from it.
Really either the 532nm greens or 445nm blues with the right amount of m/W’s or Watts
can do the job. It would take someones’ eyes a while to recover. That’s depending on the
amount they got caught with.
Do things like this really work in situations like these?
Interesting i think a strobe could help you get away by distracting the attackers they may not be able to see for a few seconds maybe even 10-15 seconds i have many times shinned the light in my own eyes. it does work! it is hard to see. But then what? If you have a gun its great it gives you enough time to aim and shoot if need be. If you are unarmed you may have a head start of running or if you want to risk it you could attack them back. But not a major advantage. In a situation where you light up an Alleyway and see some one from a few hundred meters away then it is handy you know not to go there.
A flashlight by itself is useless. The defender must back it up with a sufficient level of aggression and coordinated counterattacks to have any success in defending himself or herself against a committed barehanded attacker. Against a committed knife wielding attacker, especially one that has gotten a jump on you, even a gun may be useless. Get training, stay alert, carry a knife and/or gun if you can; use the flashlight as a last resort, but don’t make a plan of it.
Earlier this morning, for no reason at all, I watched a bunch of bear and tiger attack videos on Youtube, and now I can’t stop thinking about “What would a bear or a tiger do?” Pull a knife on either one in the parking lot and see what happens…They don’t need a gun or a flashlight to hold their own…Kinda humbling.
Welcome to BLF
The G700 / x800 can he bought from $5,- onwards.
We on BLF think it is not a good light (though $5 is a fair price for it) and sold as G700 / X800 mainly a scam.
People only knowing normal hardware store flashlights will really see it as bright.
Yet quality is lacking and for the money of a G700/X800 a much better quality light with lost more lumens can easy be bought.
This light , not really !!—But you’ve gotta learn somehow and someway ,
so just stick around BLF and you will learn lots of good flashlight stuff !
Oh and hold your pocket$ really tight and keep your eyes open until
you get up to flashlight-lumens speed, because you’re about to take a
big journey to flashlight knowledge here ! :+1:
Sue Shillander! 
not if it is light outside
not if the attacker isn;t looking or closes eyes fast enough
not if you fumble the switch or the correct mode, at all
not if he is behind you
not if there are more than 1 person
not if he is far away
not if he has a gun
not if …on and on…
i would not depend on that

Poor guy taking that to Costa Rica, won’t be able to see s 
Interesting first post.
Lights in the face followed by the hardest kick you can muster to his nuts.
What if it’s a female attacker doe?
