All of them worked. I put 3 in walkway to my back door. One comes on when I step out my back door and it is on my carport post almost half way down and two others on walkway. Plenty of light to see without a flashlight. I should’ve had these a long time ago. We zip tied one to a shepherds hook.Update I used these also on my front porch to illuminate the walk to my newly enclosed porch section.
