Let's say there is an extended power outage 5-7 days, and you are a family of four. Two adults, and two children ages 5 and 10.
Let's say that you can recharge your batteries each day, (either using your car's battery and alternator for power, or by driving to a location that still has power). OR if you use alkalines, how many will you need for a week?
Please consider,
Which rooms, and how many rooms would you like to have light;
How many lumens, you would like in each room;
would there be enough light to read or play a board game without a supplemental headlamp?
What kinds of, and how many batteries would you need to be able to supply sufficient energy for five hours each night.
Additionally would each person also have a light? If so why? To use intermittently, to go to the bathroom? or to supplement a relatively low level of light (perhaps use a headlamp for reading) What would be their power needs?
How many alkalines would you need?
How many batteries would you have to charge each day?
Eneloops AAAs, AAs,
18650's
others?

EDIT
As I write this, the thread is at post 95.
Overall, I'd say we did a nice job presenting what many people would be comfortable with. For the most part, we stayed away from particular lights, and spoke in generalities. That was my hope... I didn't want it to be another SHTF zombie thread. I wanted/hoped it would be instructional.
Well, we have gone beyond batteries for lights, to include, batteries for other power failure needs, although we only touched on them lightly, but things such as battery operated cooling fans, sump pump back-ups, and as a means to power one's furnace in the winter. We touched on using the car's alternator, or a small generator to charge a 12v deep cell battery/s.
Please enjoy reading through this thread, and make your contribution, if any at the end.
Thanks for reading this far!
