One is at my front door under a porch. The other is more exposed to weather and will be over a garage. The current ones are som sort of 20 year old heady duty metal...but they do not have a sensor. They are instead controlled by the PITA timer where the on/off switch would be in the house. (You punch a button, turn a knob to set the timer). We just want the kind that comes on when motion is detected. I am looking at these but have no idea what to look for as far as qualty goes. Will these hold up in the weather? Are they junk? Reccomendations?
