This light is amazing. I have it installed at the top of the door frame, hanging upside down. It's been up for about a month now and no signs of coming lose! It turns on every time we open the pantry door which we love, and turns off a few minutes after we walk away or shut the door. Exactly what we needed for our pantry as before it was SOOOOO dark, even with all the lights in the kitchen and dining room turned on. Attached are two photos with all our lights on, and two with all the lights off.
