Four years ago we completely remodeled our house. Everything on the inside was new, including the ceiling lights in the kitchen. We had new LED lights installed and they worked just fine. I figured that we should never have to mess with them because they are supposed to last forever. Well, no. One failed in May of 2018 and another one failed last week. Jeff, our contractor for the remodeling project, had a spare or two and he came over and installed one. I was happy to watch because it is not always obvious how to remove them for replacement. Since he brought two, we ended up with a spare. That is a good thing.
