We had to find the correct light to fit the fixture that we had because the original one is no longer available. We took pictures and Customer Service supplied us with the correct information.
At first, we had a little difficulty getting the light to fit into our recessed lighting fixture. My husband and I are senior citizens so it probably was that more than anything. We did get it to work and it's wonderful. We bought three extras because we have three more lights that could go out, and we didn't want to take the chance of this model being discontinued.
