No. It totally works with the right Nitecore light:
Lol. Never bring a knife to a flashlight fight!
That Nitecore beam stops that knife stab cold like Kylo Ren suspends a blaster beam.
The force is strong with this one.
The only anecdote I can think of where someone reported a flashlight functioning in self-defense was one I think I read on CPF several years ago.
Guy with flashlight was outside at night when he noticed several young men approaching. He thought they perhaps intended to rob him. He pulled out his light and shined it in their faces while saying “How can I help you fellas?” The men immediately stopped approaching, turned aside and quickly left thinking he was a police officer.
Of course you can disable an attacker with a flashlight beam. All you have to do is:
- Using one hand, take your 10,000 lumen light and hold it within 1 cm of your attacker’s eye.
- Using your other hand, hold your attacker’s eyelid open so he can’t blink and neutralize your attack.
- Using your third and fourth hands make sure he doesn’t move his head.
- Use hands 5 through 8 to hold his arms and body down so that he doesn’t stab you while you perform this operationg.
- Turn flashlight on turbo and blast him in the eyeball for 5 seconds.
- Repeat this procedure for his other eye.
So yes… if you’re “Mr. Octopus” you might be able to neutralize your foe with a flashlight beam! 
lol well i do have a taser so i figure that would be more effective …
i just think its funny to see these ads saying it can blind a bear! lol yea ya gonna get eaten,
OK, I’ve just gone along and tested this on myself with my Manker U11 in strobe. I’m barely able to make out the keys I’m hitting right now due to after image. Are we able to agree that even 1000 lumens is a hell of a lot of light, especially if blasted in your face from 1 meter away. I can imagine it would be quite disorientating, but not incapacitating. It’ll buy you a second or two to make an escape or reach for a better weapon.
No idea why Nitecore would make such a video. It’ll never have such a reaction on an assailant.
Take on multiple enemies. Tackle and grapple!
And should that fail, bust out your BJJ

Wait, those videos are actually from Nitecore?
Man I thought they were satirical LOL
A Convoy S series makes a great fist load or kubotan .
About the best to expect is 1/2 to 2 seconds of stunning with a temporary loss of decent night vision if it’s dark. A good camera flash does just as well if they’re not blinking. A strobe can trigger a seizure if they have epilepsy but that’s variable and unlikely in an attacker. Real knife fights ain’t like that vid- the overhead plunge only works in showers at the Bates Motel :smiling_imp:

SCS, that’s a good article.
BTW, don’t ever hit anyone in the head with a heavy light. I’m thinking Maglight here. That can be fatal and probably not why you used a light instead of lethal force. Instead, to inflict pain there are the shins, elbows and above, and such. For more severe blows there is the sternum and solar plexus, impacted with the narrow end of the light to concentrate the force. To take someone out of the action for a month or so break the collarbone. If they don’t get the message by breaking one there is a 2nd one. That renders both arms useless. At that point you probably have their attention. If not there are other body parts, knee caps and such. But not the head; never the head, you probably don’t want a potential murder charge, it can get very expensive to defend against that. Of course you’re on your own with doing any of what I suggest. You need to obey the laws where you live and take any of the consequences for anything that you do.

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?
