To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
These LED lights seem to be a great replacement for our old pot lights. They don't dim quite as much but if you are replaceing all your old pot lights at the same time, this won't be a problem. If just replacing one in a set of lights, you will notice a difference in the level of brightness/dimness.
Bought these in January 2016 and just replaced several in April 2021 because they were flickering and it was steadily getting worse. They were fine for the first few years but don’t expect anything like the 23 year lifespan from the description.
