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've bought many CFL bulbs in my life. These are rated as Color Rendering Index 82, which isn't a very high number, but I think they might be even lower than that compared to other bulbs I've bought. The light they give off is seafoam green, like the worst kind of subway corridor lighting you'd see in a '70s industrial era Soviet film. Do not use these anywhere there are people or food you want to enjoy the sight of.
