Re: Best \'building disaster\' light
OK, yes, a light in that situation can be very comforting. Even something like a single LED, but a bigger light probably helps more. I guess 14 hours of good light could be an Arc LS with a 123 inside, maybe a spare loose 123 for normal replacement, and a sealed 5-pack of those 80-cent Lisun 123's tucked away for emergencies. Or for less light, an Arc AAA and a 2-cell or 4-cell shrink wrapped pack of spares would give that much runtime. I guess the weight and cost aren't too bad either way.
