Review on SUNVIE Battery Operated Motion Sensor Ceiling Light, 300LM LED Indoor/Outdoor Battery Powered Ceiling Light for Hallway, Bathroom, Stairs, Basement, Warehouse with Photocell Sensor ON/Off by Stuart Dunn

As many other people have mentioned, the lights keep going on and off at the wrong times. We placed them at the bottom of the stairwell, which we rarely use, so the light comes on when we need it. When the light is on it's very bright and the installation isn't bad either. The problem is that the light flashes on and off every few seconds. Tried both settings, same result. At night it just turns on for a few seconds, then turns off, turns on, then turns off. There would be no movement to bring it about. My house is 110 years old, I hope there are no ghosts in it, but there is always a chance :)
