Review on 15W Motion Sensor LED Ceiling Light, 1200LM, 3-in-1 3000K/4000K/5000K, 7.5inch Flush Mount Fixture for Doorway, Stairway, Corridor - Pack of 2, Non-Dimmable, White by Liz Garcia

The mounting screw hole spacing is about the same as the electric box, therefore all the screws are only on the edge of the box, making installation impossible without modification. The color temperature switch is only accessible before it's installed, so make sure you set it before tightening all the screws. And it's a big switch that sticks out from the back making the setup another PITA. If I had known all this, I would not have bought this product. However, the motion detection works.
