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.
I was skeptical about ordering fragile light bulbs online, but I did not have access to purchasing them locally. I am pleased to report that all four bulbs arrived intact, were easy to install in the light fixture, and provide light as expected. However, I noticed the bulbs don't seem to last as long as the ones I purchased locally. I typically have the light fixture on (in the kitchen) for 14 hours a day, and I've gone through 3 bulbs in only 8 months. That seems short to me.
