Motion Sensor on Front Door

Just before one in the morning on September 8 after my LCD lab I opened my front door in the dark.  As a I approached my house the door light came on.  I think it uses an asymmetric reflector.  When the light senses me the intensity ramps up over a split second, not instantly.  It is very white and on the warm side of color temperature.

I expect it now and I usually squint before I reach my front door.  It also reminds me of the Halloween time of year in Michigan.  This is because I have a memory of walking through my neighborhood asking for candy and seeing these type of lights working.
