As mentioned, if it's the LED lights you are referring to, MOST of ours come off easy. However, the one in the bathroom just would not come off, no matter how hard I tried. I finally got my very
large pair of slip joint pliers, and very gently gripped the edges, twisted slightly, and off it came. Turned out that they had screwed the base so tightly to the ceiling, and one of the tabs was bent slightly, it put it in a bind. Fixed all that, now it goes on and off easy. Conversely, the one in the kitchen, two fingers and off it comes!
