anyone bought a motion-sensor AA-powered night light?

I’m looking for an AA-battery-powered LED night light with a motion sensor, to stick on the wall of my stairwell. It has to be battery powered, since there’s no AC outlet in the stairwell. It would be great if I could find one that uses 18650s, but I’d be happy with an AA one.

There are several models at DX, but I’m hoping someone has actually bought one and can recommend it.

The sensitivity of the motion sensor is more important than the brightness, but brightness is important too.

Thanks in advance.

I built one… for my toilet. It was very easy to do and works great: Nichia 219 Motion Sensitive Piss Light
