Review on Dimmable Microwave Oven Bulb Under Microwave by Rob Bishop

Works Great on High! Much brighter and cooler than the incandescent bulbs that came with our Samsung microwave. The lightbulbs that came with the microwave got so hot we were afraid even to leave the light on for more than a few minutes at a time. And they were so dim, even at maximum brightness, that the light from a brand-new microwave was useless. These LED bulbs stay cool and really light up the oven area. On "high" it works fine, but on "low" it flickers. I still gave it 5 stars for its brightness and coolness. If I really needed a lower light level I would give 3 or 4 stars. Maybe it just doesn't work well with our microwave on low, but it might get darker in other situations, I don't know, so I didn't want to lower my rating based on that one negative experience. In general, the light is excellent, bright.
