[CORattler]

I installed one of these to light up my stairs to the bedroom so that when I wake up at night to go downstairs or even the bathroom I can see where I'm going. I mounted it above the middle step and positioned it so that it also lit up the bedroom floor. It turns itself on and off with a built in motion detector. It also has a built in photocell so that it won't come on when there is sufficient light in the area that it is mounted. Takes 3 "C" size batteries. It's LED so there is very little power consumption and provides plenty of light.Works like a charm and was inexpensive and very easy to mount.
