Which brand do you think is most durable? Your life depends on it and so does your family.

Once you bump up the food , I like high end water filters MSR and Kataydn water filters. Then boil for virus destruction if needed. If the micron of the filter is not small enough.

Other people will die let them if they are not intelligent enough.

You did what to a Surefire?.
What version of the Defender.
I have eight versions of the Great Defender.
And maybe I don’t have ’em all.
None of ’em will ever hit concrete. They levitate.
They gave you a Chinese fake junk garbage.

Similar to the one pictured. With Surefire prices they charge : Not standing up to my tests at at all. Total JOKE. I would buy Surefire for collecting only. Not field use.

Other brand stood up to better abusive/impact test conditions than Surefire. And at a FRACTION of the cost.

The United States Armed Forces are in dire need of your professional advice.

Correct. My Dual Engineering Degrees would help them for sure.

Bachelor Of Science in Structural/Interface Design

I’ve had 2 Surefires quit on me, both were the more modern LED variants.
I’ve had fenix quit on me. Not the eo1 though, it will never die.
I’ve had cheap ones quit, i’ve had expensive lights quit, the only real answer is to have many to choose from.
I have a few LED lensers now, while they are often not the first choice for flashaholics I find them tough and functional. One is rechargeable, one runs on easily sourced aaa batteries.

I had an HDS years ago which I stupidly sold, I wish I had kept it because that would be my answer for the one unkillable flashlight, the downside (for me) being that they ran on cr123. My preference these days is for AA, AAA or USB chargeable units.

one thing here is, everyone has had something fail.
those are just isolated incidents.
what would matter is some huge survey of things that lasted, things that did not, why, and what the use and application was for all of it

also, usually in surveys like this, the complainers are more numerous than the satisfied users.

another thing is, i don;t really think quality translates directly to cost
and some results here bear that out

there are many reasons why things may cost a lot
it may be an attempt at quality that still failed
it may be looks
it may just be marketing - charge a high price and someone will believe expensive must be better

I think you are right wle. Anything can & will fail sometimes. I have never had a Convoy or Maglite fail…. but this does not mean it could not happen. It surely could.

I have had 1 Nitecore fail, a bad electronic switch; but that does not mean Nitecore is unreliable. It was an isolated thing.

I think for me what I want in a last ditch SHTF light is simple. Manual switch & simple controls. AA compatibly would suit me also. Eneloops are hard to beat.

If you want real unkillable light, get a Solarforce (Al) or NexTorch (nylon) with a real hotwire-bulb drop-in.

Won’t win any lumen-output awards, but it’ll outlast even the cockaroaches.

I’ve a slew of old ASP and Streamlight lights that have endured daily abuse. Since the turn of this century I’ve always carried a LRI Photon light on a neck chain. Extremely reliable and there when others were not.

I’m sure your scientific tests will help the country.
And your degrees will impress the Pentagon.
Uncle Sam will stop buying Surefires immediately.
Just don’t go with “the one pictured” thing.
You can end up in jail.
For wasting their time like you waste yours.

My daughter grabbed my Convoy L70 blaster out of the drawer at 3am to scare off a burglar. She walked past the simple one button lights I’ve left out (her fav the Nitecore MH20GT) to get to it. She pointed it at the douchbag. (drumroll for blaze of blinding light) whahhh whaaaaaa…the light didn’t work ….so she called the cops. Burglar didn’t see her at all despite her being @15 feet away and the cops arrested the guy.

Oh, turns out that you have to press the damned tail button FIRST, before the side button is hit to turn on a L6. That’s all. Flashlight worked fine after all, the officer, daughter and I all got to laugh about it @3:30am.

Here’s a better thread for this kind of content.

This is why the whole idea of mech/electronic dual-switch lights irritates the hell out of me, either you want turbo right away and it comes on in low, or you want low and blind yourself with turbo. Then, after turning it on you need to use two hands or completely change your grip on it to cycle the modes. No thanks.

OEM, untouched: Fenix

Figger it’s dark for 12 hours +/-(unless you’re in a cave or far away from the equator); so an astrolux a01 on low should last all night; 3 of them just to be safe; you’re going to have to run high occasionally.
For a weeks worth of outage I would have 6 on hand with solar to power my charger.
Throw in a few i3eos for good measure.(I ran one continuiously for a little over an hour with a aaa bonai1100mah rechargeable).
They also fit little hands without getting hot enough to burn.

My wife removed my right ear on the usability of my collection of flashlights.

Keychain olight….unscrew it

Q8….ramping

VG10….tail switch

TK15……side switch

TK45….two side switches

She asked with all honesty….in an emergency, why should I expect her to remember which flashlight she has in her hands and how it works?

My answer is obvious. Trade her for a flashoholic wife Find a cheap floody light, in red anodizing if possible and buy several of them.

Do not reply with your NONSENSE. Unless you are QUALIFIED WITH DEGREES do not make ANY TYPE of comments pertaining to Engineering, Design, Build Quality, etc… You DO NOT ANY platform to make those type of comments.

Surefire is A JOKE. Especially the prices they charge. I had a Surefire FAIL while other brands stood up to SAME test guy.

Back to subject at hand. Another poster mentioned complainers more than satisfied users of certain brands. I layout and specify that Surefire and Elezetta FAILS like any other light in circumstances. Along comes a elbakan1 trying to play hero in thread really WASTING thread space

You think that you are well prepared to the end of the world, but it’s just a scenario, you absolutely don’t know when it will be your time to say bye-bye.
Did you notice this small lego on top of your house stairs before going down to the kitchen at night ? Ouch…broken neck 2 seconds later.
Yeah, stupid accidents happen every single day even the less expected one.
Stayin’ alive, stayin’ alive…ah…ah…ah…ah, stayin’ alive is not a matter of intelligence, only chance.
