ok, i love this thread... I'm a prepper too, though not as much as i would like to be... I want to learn more!
But for light I have multiple led lanterns that are very bright and last for a very long time. I have water stockpiled for a month, and canned/dried food for several months. There's only so much I can keep in a 1 bedroom apartment... bc if the shtf, I can't carry all that with me. :-)
