Review on WB36X10003 General Electric Microwave Light 💡 Bulb Lamp - 3 Pack: 40W, 130V by Ricky Lahoti

These bulbs may not last as long as the original OEMs (SIX YEARS!) but they're still good. I use a light under the microwave to create a general low light along an overly dark section of the counter. That means I leave it on almost all of the time, every day. I just checked and my last purchase was exactly 3 years ago in 2017. This was a 3 pack so I'm guessing they last an average of 12 months each. Again, this leaves them on almost 24 hours a day, 7 days a week. If you only use the light for a limited period of time, they will last a long time.
