Would a EMP burst render all of out lights that have circuits in them useless?
Should I buy a few Incandescent P60 drop-ins just in case?
:~
If I am not wrong, the EMP will also make un-usable Li-ion and NiMh cells (plus car lead-acid batteries).
The only batteries able to survive are alkalines…… I dont know what will happen with Lithium non-rechargeable.
So, incandescent lights powered with alkaline cells. I have some prepared for… in case of that event……
But, again If I am not wrong…. There is a lot of contradictory info about EMP on Internet
Wet cells would survive. On the other hand whatever you want to protect, store it in an old microwave (or just make a faraday cage).
I keep most of my flashlight stash and batteries in cardboard lined ammo cans. The can provides the faraday shield and the cardboard insulates the metal contents from contacting the inside of the ammo can.
This setup was by accident, I just wanted something to store my lights and batteries in , it just happens to be emp proof. From what I’ve read you can wrap a flashlight in tissue and then wrap it in tin foil for the same effect.
The ‘other’ site I think, has done this subject to death.
No pun intended, I’m sure, but if there is ever an EMP, we’ll have bigger problems than our flashlights.
EMPs built by humans wont affect a large area, so no problem there. As for a "worldwide" EMP caused by the sun or sth.. yeah, we'll definately have bigger problems. And campfires all over the place anyways, so.. :)
Why? Because of radiation, blast wave etc. ? Well yes, but think of the possibility of a ‘EMP only’ attack, where a nuclear device is detonated in the upper atmosphere. For this scenario a flashlight would be a very useful thing, since there probably would be no more electricity.
Don’t get me wrong, I don’t consider this to be very likely, but from time to time I enjoy the thought of being prepared. At least it is an excuse to haul around a ton of EDC-stuff like I do 
So to answer the question in the OP, HDS systems claims that their lights are EMP proof. Since budget lights are constructed in a very similar way (circuitry and cells inside a metal tube, glass lens, clicky in the back), I don’t see why they shouldn’t survive EMP in the same way.
I haven’t read about batteries being sensitive to EMP though. Sure, PCBs on LiIon cells would be fried, but non-protected cells should be fine, no? I would like to read about that if anyone can elaborate.
In any case, having a spare P60 host with an incan drop in and a few Li primaries in a metal box won’t hurt… I also keep a crowbar under my bed in case the zombie apocalypse happens during naptime 
And since this is a budget forum, what do you think: is wrapping a light in aluminium foil enough to protect it from EMP?
I have an large metal gun safe which I keep some back up lights, batteries and a pre-pay cell phone not that any of the cell towers would work after an EMP, but it helps me sleep better.
Unfortunately I only live several miles from a sub refueling base, an active air base with a C-135 refueling wing and a nuke plant. So there is no doubt in my mind there is a giant bulls eye painted on a map above my house.
I wasn’t trying to suggest flashlights won’t be useful after the the grid goes down, clearly they will be, I just meant that those of us who follow the boy scout motto will be more concerned with fending off zombies than anything else. And lets be honest, an MBR, some pool shock, and heirloom seeds will all be more useful than the torch I use to impress my friends.
That’s all my wife need to see to finally send me off to the looney bin, 15 flashlights wrapped up in aluminum foil. HEHEHE :cowboy_hat_face:
My impression is that an EMP would be disastrous for devices that are turned on, but will it affect devices that are Off or do not have batteries in them? Is my thinking incorrect?
This chat me of a scifi movie I saw recently, where the only radio working was one that was put in a bird cage, and in another scene a guy had his entire apartment turned into a giant Faraday cage to hide from the aliens… :bigsmile:
Devices that are unplugged will not escape getting fried…
It will afect both switched on and switched off devices.
Also some batteries will be affected, as I have found over internet:
Affected: Ni-Mh, Li-ion, Lead-Acid.
Not affected: Alkalines, Lithium primaries.
I can not tell if it is true or wrong……….
Was it The Darkest Hour? ;)
I have to side with Troop, except that I think batteries would need to be pulled as well. What little I know about an EMP burst, I do not think it will affect unpowered electronics, but I could be wrong. Someone more knowledgeable on the subject, please share your knowledge.
that’s what I thought, as far as circuits are concerned (no knowledge on batteries).
ie, my D06 and Klone35 draw current even w/ no output, so they’re toast if I store them w/ batteries in.
as far as a flashlight’s utility after any sort of nuclear attack (sub-surface, high altitude, etc) - I don’t see why you wouldn’t need a flashlight as much or more. IOW, if you’re not going to say ‘screw this’ and off yourself, then you’ll be very happy to have a working one…
Bull sheet
Like everything collapsing into a Mad Max/Bartertown culture. No thanks, I’ll trade my lights for a bottle of barbiturates…
Would you like to back up why you feel that way?
