Query: Great Product

I was desperate to have light in a cubbie where I keep all our personal financial files. There was an electrical outlet inside which made it a perfect application for the automatic light. I had tried a battery operated light, but it was not bright enough to see into my files. This product works great. The light comes on when I open the door, floods the cubbie with light, and turns off when I shut the door. Perfect!
