Yes. That's what I did because I'm a renter and the old man lives too far to come out for maintenance. Just use two sets where there aren't seams . Cut to size and place on the base after you screw the halves together. Use the heavy duty 3M Command strips for large pictures. They're long and black and they hold more weight. Just a dollar more about 8 bucks. Mine hasn't fallen on my neighbors' heads so it's good! Neighbor downstairs moved out and turned off her electricity and you guessed it! The hallway lights are connected to her bill!!!
I have found this product to work exactly as the advertising says it does. I installed two of them in my storage shed and the installation was easy and they provide excellent lighting.
Probably not the best idea. It could be done if you can drill out the tile, assuming ceramic, without chipping the tile and then using a screw with a plastic sleeve.
Yes, I don't see why that would be a problem.
It requires 4 C cell batteries.
I see you asked this question back in April so I hope that you have returned the light for a replacement. It should not stop working after 15 minutes unless the batteries have become dislodged somehow.
Yes. Perfect for that spot!
No you cannot disable the motion detection. You can do the opposite and disable the light sensor so it only comes on with motion.
