Default LED flashlights and EMP

I just want to bring to the attention of folks the possibility of an EMP (Electro Magnetic Pulse) trashing those LED flashlights. Since an LED is a diode ( Light Emitting Diode) and as such is a silocone based semicomductor, it too would be trashed just like any transistor or integrated circuit. This would also include any device employing an alphanumeric display, LED or LCD (Liquid Crystal Diode) such as this found on radios, computer monitors, scanners, clocks, etc.

Those old fashioned flashlights using an inefficent incandescent bulb I guess would survive. This is just conjecture as I have never been through an EMP. You might want to consider buying one of those wind up or shaker flashlights and wrapping it in an insulator such as a sock and then in some tin foil and setting it aside not to be used until after the dust settles so to speak. I have even set aside a spare computer and distributor for our old 1991 Toyota for this reason. Come to think of it a solar cell is also a silcon base seimconductor.

One last thought, while looking for a new empty paint can for storing our heirloom seeds it occurred to to me that it would make a good container for storing electronics. It is metal and water tight though the outside could use a coat of paint because they rust easily. Sherman Williams Paints wanted 4 dollars for a one gallon can but a local paint company, Halman/LIndsay charges $1.79. Also those tins you got your holiday cookies would make great enclosures.
