I don't even bother buying tea lights anymore, not worth it IMHO. I just use my oil lamps for power outs and at bedtime I just blow them out and go to bed. I'm not afraid of the dark and it's not dark that long. I do keep an LED flashlight by the bed just in case I need to get up for anything. I've never felt the need to stay up to see when the power comes back on. It may be a psychological thing but I know people that can turn off all the lights and sleep like a baby but if the power goes off they can't sleep til it comes back on.
