I have one of these on the back of the house, works great unless we have 3 days without sun, which is something that we get often during storm season. I'm going to wire in my 12 volt power backup into it https://www.homedepot.com/p/Nature-Power-Dual-COB-Black-Outdoor-Solar-Motion-Activated-Security-Flood-Light-with-Integrated-LED-22060/205351548
We have solar motion detecting lights I bought from Costco that are incredibly bright. I also love all the solar lights at Harbor Freight. They work really well. I havent had an issue with them but we also live in zone 7 TN.
