I had written last year about good success installing a Commercial Electric ceiling light fixture. While these are indeed easy to install, I recently put up one more in a small room, then drilled a screw into place on an adjoining wall, and the glass dome fell off to the wood floor below and shattered.
Reading the relatively few 1-star reviews of the product, apparently some other people have had the same problem. Since I really don’t want that to happen again, I think I had better find something with a more secure cover.
Another reported problem is that the glass domes are too hard to remove at all. When I went to take down the other two that I had already put up, I found that I couldn’t just unscrew the dome as expected. A big thanks to Sanjeev Sabhlok for hosting the answer!
These particular light fixtures also appear to be increasingly hard to purchase; perhaps they were discontinued?
