Multiple times during the outage I forgot where I had placed my flashlight. I think the best device you can have is a cell phone which can be used for communication and light. And keep it near you. (although I do not put my cell phone in my pocket unless it's turned off because of radiation.) Also they make headlamps which you can buy for between 1 and 25 dollars at Walmart. You don't want to have to hold a flashlight when you are busy with things! Good luck with the prepping bro. I'll continue to share all the great information I find with you guys.
