Because a microwave light isn't on for as long as all the other lights. It also has a shorter element, thus it's stronger. What "wears" out light bulbs is the constant turning on and off. The surge of electricity when you turn it on adds more stress to the element than a bulb that is left burning. Burning is what happens, and why it "burns" out. Why do you think it gets so hot?

There are a number of possibilities:
1. You buy cheap light bulbs but splurged on a quality microwave.
2. You leave the lights on much more than you use the microwave.
3. You have an anomalous voltage, either continual or spiking, which is filtered out by the electronics in the microwave, but not for the lights.
Try buying the longer-life bulbs. They cost a little more, but you replace them much less often.
Have your voltage tested, or test it yourself, being sure to monitor it over time so you have a chance to catch a spike. (Voltage testers are available in most electronic stores, including Radio Shack, and places like Sears).

They use, what is called an appliance light bulb, which lasts much longer, than an ordinary light bulb. The same type are used in your refrigerator, which you hardly ever need to change. Your refrigerator light is on much more than your microwave light, and it still hardly ever needs to be changed. They also use them in your oven, and most appliances..I hope this helped..

Incandescent lamps can be designed to last for different periods of time. However, the design process involves a tradeoff between lamp life and brightness. A long-life lamp that is going to be less efficient, generate more heat, and not be as bright as a lamp designed for the general illumination of your home.
If you would like to try a long-life lamp just to see for yourself, you can purchase a "Rough-Service" bulb at the hardware or automotive store like those that are used for trouble lamps and install it in your reading lamp. It will last much longer but will not be nearly as pleasing to the eye.
