Product review (2 stars): Check your max wattage
Before ordering, check on your microwave for max wattage. The description here says this is a 20 watt bulb, but my microwave/hood combo says max 10 watts, so I'm not sure how this is the same model #, and OEM, if it's the wrong wattage.

As another poster said, NEVER touch a halogen with your bare hands; the oil from your fingertips (even if freshly washed, there's still oil) will heat up and cause the bulb to fail quicker. Use rubber gloves if you have them, or use a paper towel or napkin.
