Motion activated flood lights
Hello one and all, I am wanting to install a flood light on my drive way that is motion activated. However the tricky part is I would like it to have a battery back up but run on house power that only comes on at night. Does anybody know of an existing product or how to wire one from scratch.

You could wire a conventional motion activated light so that it light plugs into a UPS designed for computers. These lights have a sensor so that they do not turn on during daylight.

Not sure why you would need a backup power source on an outdoor light. I would think the moon is a pretty good backup. Save the battery backup for the interior of your house.
