step lights with motion sensor



I am looking for step lights with motion sensors built in. My sister-in-law's house came with these installed. They are small lights inside a standard single gang box (orientated verically) with a louvered cover to direct the light downward. They are located about 12" off the ground along their main staircase from the upper level to the main level. At each end, the unit has a motion sensor built in to turn the lights on. They stay on for about 10 mins when activated.

I have goggled the entire internet and cannot find these things! My electrician and the lighting store have been no help. Has anyone seen these anywhere?


To clarify ... Is the sensor built in to each light, or is there one sensor at the bottom and one at the top of the stairs?
