I put these outside our back door because it's soon dark back there at night. We do have a light back there but it's still super dark. I actually prefer these to the actual light because my husband always leaves the back light on. With these he just needs to walk out and they turn on. I don't have to worry about whether or not he's turned them off either.
The sensor seems to work great. So far it's worked every time we've walked out the door. We don't go out back often though. The lights are bright enough to see but they are no flood light.
