Don't bother. This is awful quality and the cost isn't worth it.
I tried so hard with this, recargeable high capacity and disposable batteries... Nothing would last longer than a day and a half. I needed a sensor light enterfor the hall landing, I go through the hall maybe 3-4 times at night when it gets dark. I'll come home about 1am (I'm ta and chef) then go for a shower, have my dinner and go to bed. That's it. 3-4 times max and it still doesn't last
