When TSHTF, will my LEDs still work? LED. Stands for Light Emitting Diode. In the event of EMP, will my Diode cease to function?

Good question, I'm curious about that as well. I certainly hope so.... I have other lights, but the LED is awesome for long term.

Re: When TSHTF, will my LEDs still work? I wouldn't think they would be affected,unless having batteries in them would somehow become a conduit for the EMP.Typically EMP will not destroy electrical components unless they are ON during the burst.Almost all electronics that are on when an EMP burst occurs will fry. But i do know when a burst is anticipated,SOP is to make sure all electronics are in the off position.

Re: When TSHTF, will my LEDs still work? Very good A , I am with you on that.

Re: When TSHTF, will my LEDs still work? If I get an EMP from an arial burst I'm not going to worry about my stupid flashlight. .

Re: When TSHTF, will my LEDs still work? EMP won't hurt you.If it is any type of air burst,it will be in the ionasphere[sp.] If it is a ground detonation like a stolen nuke......you are probably screwed anyway and a flashlight won't be needed due to the after glow......

Re: When TSHTF, will my LEDs still work? Contray to popular belief, all nukes have an EMP. By "arial burst", I mean a deployed ICBM. Nukes are not normally designed to detonate on the ground, they detonate over the target. .

Re: When TSHTF, will my LEDs still work? I've read somewhere EMPs are on a long wave legnth and Chicken wire could be a help in blocking them. Maybe leds are small enough that the wave trough would allow them to slip thru unharmed.

Re: When TSHTF, will my LEDs still work? EMP is a pulse and any long wire will catch a charge. Shielding with proper grounding is required. At SAC we called it "hardening" the electronic equipment. .

Re: When TSHTF, will my LEDs still work? I can't tell you if this is helpful but this is what we were instructed to do when I was in the Army being just a humble radio operator (SSB) insofar as preparting for an EMP event. Disconnect antennas. ummm... That's about it. If your storing electronic equipment for use after an EMP event I'd recommend lead lined boxes underground as an ideal. Honestly, if you can block RF then your equipment is EMP safe. Examples that would come to mind are tunnels where the radio station goes dead.

Re: When TSHTF, will my LEDs still work? Halo? a E bomb doesn't have to be nuclear and it can be made for as little as $2,000......all you have to do is to place it on top of a tall building and detonate.

Yes, but the range and effects would be much smaller. A 2000 pound microwave munition having a minimum EMP radius of 200 meters. Not certain what the maximum range is. Probably has more to with exposure of antennas, etc. If somebody is dropping microwave munitions I'd be more worried about fragmentation/blast effects then EMP. A nuke, OTOH, causes an EMP pulse for quite a distance. Especially if its detonated from space;1000 mile radius! Near ground nukes can cause stronger EMP damage but are more of a tertiary concern (at least to my mind) if employed in this configuration.

The last I heard, a nuke big enough to cause a nationwide EMP is going to have very severe and immediate radiation emmissions down here at ground level...

The radiation is not a concern. A 1 MT burst at 200 miles, above the ionosphere, would not even be visible (except for possible "auroral" effects) and the radiation reaching the ground would be minimal, but the footprint (line-of-sight) would cover most of the geographical US. The X, gamma and neutron radiation slams into the ionosphere/upper atmosphere and causes a very sharp (short risetime) shift of electrons over a huge area, which causes a downward directed electromagnetic pulse of similar characteristic that can be picked up by power lines, antennas, data cables, etc. - and propagated into your electronics. In the case of the more conventional "microwave" EMP bombs, the microwave pulse is harder to shield against because the much shorter wavelength energy can propagate on metal panels and and through vent slots, holes, cable port openings, etc., which may even act as waveguides at those frequencies depending on their size.

Nope. No relation.
