This light fits my Panasonic microwave perfectly and after almost two years of cooking and reheating in the dark my wife is thrilled that she can now see what's inside while sipping her morning warm cereal and other foods prepared. Did a little research. In order to find this particular bulb I decided to order two since the original bulb only lasted about 5 or 6 years. I also watched a few YouTube videos to see how to replace it, which turned out to be the easiest part. Work. The hardest part was that Panasonic saw fit to use Torx screws with a six-pointed star and a pin in the middle, so I couldn't fix my own mount. Another YouTube video showed me how to get around having to buy a special screwdriver just for this purpose - YouTube rules when it comes to helping you do things yourself and saving yourself the trouble of buying special tools - just enter an alternative to a secure torx screw if you are facing this problem. I have to admit that I agree with my wife and appreciate that I have the light back. Don't hesitate to buy these lamps instead of buying overpriced original lamps!
