How long with this power a led Answered

I have an idea for a nightlight for kids or even adults in the hallway or something.  But I am running into a problem.  The main housing for this light is going to be pretty small.  I was first planing on running this off a household electrical plug and that would work best.  But I would not know quite how to step down the power from the wall to only run 2-3 led lights.  I am sure I could get some sort of small circuit board that would drop the current.  However because of the small housing I doubt I could fit that in there.  I know I am not giving a whole lot of details but I do not want to give away my idea quite yet.  What I am wondering is how long would say 1 AA battery run 3 LED lights?  I am thinking this idea is not going to work out because people are not going to want to have to replace there battery every week or even more.  So if anyone has some input on this idea then please let me know.  The housing I think I would have to work with would be something like a pipe that is maybe 1 inch across the opening by about 2 -3 inches long.  So nut much room to work with at all. I await your replies.

There are so many LED nightlights at the home centers. They are pretty small and have daylight on/off sensors or motion activated ones. They plug directly in the wall for power. I haven't taken one apart to see how they work though. They are relatively inexpensive to hack and easy to mod the decorative element on them.

1AA? Then i assume you will be using a jewel thief between the battery and LEDs?

To get an idea of how log the battery will last you need to know how much power the LEDs will be pulling. So what are the specs on the LEDs?
