Review on Dimmable Microwave Oven Light Bulb (Pack of 2) - Ceramic Body E17 LED Bulb, Warm White 3000K, 8W (Equivalent to 70W Halogen Bulb) by Austin Wolf

I liked that they are brighter, help to see what's cooking. . First, many microwaves still provide a small amount of power when turned off, meaning the bulb is still dimly lit. The problem isn't with the lightbulb, it's with the way your microwave works. If the light needs to be 100% off, do not replace the incandescent lamp with an LED lamp. Second, they're longer than the incandescent bulbs they replace, so make sure they actually fit the space you intend to use them in.
