Review on 🧊 Sterl Intermediate Refrigerator Incandescent Lighting by Wagner Witlin

Bought to replace the light bulb at the bottom of my high power microwave that lights the hob. The first of these bulbs I used blew out as soon as I turned on the light. I decided to try the rest of the lamps to see if they worked. Another blew up as soon as I turned it on. The other 4 out of 6 turned on in both normal and low light, but I don't know how long they last. I attached the photo. The first consists of two burned out lightbulbs placed side by side. One had the usual black tan on the bulb. The second photo shows a lightbulb that has not burned out. Note that the thread is spring wire in a simple horizontal "V" shape. This is what it looks like in the pictures in the product catalogue. In the photos in the product description, the thread is shown as a straight wire that is raised and lowered several times. I returned the package because an instant bounce rate of 33.3 is not good.
