I have a flashlight with two-pin bulbs. I think it's called the GU-24 based on the product and I wanted to convert it to a regular rotating light fitting called the E-26, I think I've always called it a light rosette. They are easier to find than those with two posts. Anyway, this product came quickly because I have Prime. It was a perfect fit and worked the first time. I use it with LED bulb. It's comfortable to the touch and sturdy, and two come with it so I have one in reserve. I'm very satisfied with this product.
