Product review (1 stars): Garbage! Do not buy!
I bought two of these bulbs for my GE microwave after the second one burned out. It had lasted nine years. The other went last year.

These bulbs arrived unpackaged and unmarked. I don't know if the are the correct wattage, or even the correct voltage. They are significantly shorter than the OEM bulb, and the prongs are much thinner.

I installed both and turned them on. They both lit ... for about five seconds, then the first one burned out. The inside turned milky white.  The second one is still burning, but for how long? I wanted to buy from Home Depot, but the wife said "This is easier." Returning this garbage won't be easier. I guess I'll just eat it!!
