What's that movie?

Hey guys.
Just new to the forum here. I remember when I was a kid I seen a horror movie. I remember one part in particular. It was a girl (good) and a crazy man (bad) locked into a small confined area almost like a closet. There was a ligh bulb in the closet and the girl decided to smash the light bulb so the guy couldn't see her and she escaped. From what I remember the guy was wearing almost like a hospital type outfit and wearing sandals.
I know this is not much to go on but does anyone know the movie I am talking about?
