I picked up a couple of cheap solar LED lights meant to be staked out on the lawn to mark paths, etc. it looks like the units can be removed from the stakes. Could be cleaner and safer than candles and other sorts of fire based lights in case of emergency, and the lights come in different sizes so different light intensities. I thought maybe i could keep a couple on the window sills of the house during the day and place them in strategic locations after dark in SHTF. How long do the little buggers last, anybody know? the ones I found were $2 each. If they last longer than a few days they would be way cheaper than candles and the not needing fuel except solar could be very beneficial. brainstorm away... I'm curious to find out what everybody comes up with.
