Given that many of the lights we rely on as primary lights frequently have less than 3 hours of runtime and we can only have so many extra batteries (well OK I know some folks have quite a few extra batteries, but assuming you've got on average 1 or 2 extra sets) what is everyone's last ditch long runtime backup light for when the storm hits and the power goes out for 3 or more days (which I've had happen even in a bad storm around here)?
