E17 LED T7 T8 Medium Base LED Appliance Bulb, Dimmable, 4W (Equivalent to 40W Halogen Bulb), Daylight White 6000K 110V-130V, Ceramic E17 LED Bulb for Microwave and Oven Appliances Pack of 2

The lights just stopped being bright. There are two settings for light on my microwave and they are both dim. It worked for a couple months, and now it’s just barely visible and the two settings don’t have any difference in brightness for whatever reason. Maybe I had a bad batch, but for now I would just try another brand. Both bulbs are having this issue.

Longevity: Installed the first bulb on February 6, 2019. Writing this review January 21, 2020 as I have just now needed to change to the second bulb. Original incandescent bulb that came with the microwave lasted from October 2017 to February 2019. If you are wanting this bulb because it will last longer - it won't, it is almost the same. Color/brightness: The color of the light is a lot more on the "cool" side, closer to the 6000K Daylight White (the there is also a 3000K color rating in the description). Function: this is one of the only "dimmable" LEDs that will actually dim to the low setting without giving off weird flashes. Also, it does not turn completely off when light setting is turned to off. It is a little shorter than the incandescent equivalent, which definitely helped me fit it in the socket.

These lights are not super bright but, they work and sim also. Great for price and will put last regular move power consuming bulbs.

Much Less Power Used, MUCH Cooler To Operate! Not quite dimmable though... One star removed because there is a little bit of flicker when dimmed (microwave has a night light function). These fit and function perfectly at full brightness though without creating an excessive amount of heat, which is mainly what I was looking for to begin with. **UPDATE** I have changed my rating on these LED bulbs from 4 stars to 1 star because they both stopped working completely within 3 months of intermittent use (only 4 hours/day average). I suspect it may be because they aren't actually designed to be used on a dimmable circuit, despite the description stating otherwise. I am not going to seek a replacement from this seller, as they will likely fail again for the same reason.

I ordered these E12 T bulbs because they looked like they would physically fit in my low-end Whirlpool OTR microwave oven hood. I was tired of buying a new bulb a couple of times a year or so, so I thought these would last better. They DID, but have a weird defect... they never turn completely off! The three options are bright, dimmer and dimmest, where ordinary bulbs have bright, dim and off. I'm finally entering my review now that I've found some new LED bulbs with a higher color rendering index, and which actually turn completely off when that setting is selected. What an innovation! (Hint: search for "dimmable" bulbs. I didn't know!) Even running all the time, these DID last for a couple of years. I think one of more of the COB LEDs blew out. So they lasted OK. Your mileage may vary.

I have tried other suppliers for these LED lamps. I just got this one (2 in package) and installed it into an over range/under microwave fixture. It works perfectly and the light temperature is exactly what I wanted. The one it replaces was more yellow and the illumination faded over a period of a year or so. This one starts out with more of a daylight color and is much brighter. Seems very well made also.

Was having problems with halogen bulbs burning out too quickly on the under carriage of the above stove microwave. These bulbs are very well made and at a fraction of the price of in-store bulbs. They are plenty bright and just the amount of light needed. I needed something dimable because my microwave has low and high setting. If yours has a setting like this, you will need a dimable bulb or it will blow prematurely. We'll see if these stand test of time but looking at the quality, I am not worried. I will update this review if I have any problems.

[Update: After going through 3 led bulbs for the interior microwave light, all failing in a few seconds, I have dropped a star. It is possible there is something with the MW that is causing this, but the incandescent bulb continues to work and the work light (using the same led bulb replacement) works fine. Great replacement as it is brighter and whiter that the standard 40w incandescent.] These would be excellent replacement bulbs for my GE over the Range Microwave oven as they fit both the interior and exterior lighting. Typically, LEDs last more than 20,000 hours. 1 of the bulbs works and is still working. The second gave me the sensation of traveling more that 20,000 hours forward into time in 1-2 sec as it only lasted about that long. The interior light on this GE oven is difficult to change due to space and after testing it was working, I proceeded to reassemble The light wink out a few seconds after power was reapplied. Yes, I did recheck and the bulb was tight and that the old incandescent bulb still worked in the same socket. Even reinstalled the LED after confirming the incandescent bulb still worked. The LED bulb is much smaller diameter than the incandescent it was replacing, making the fit much easier. The light is white and far brighter. The exterior light on the MW has a full and dimmed setting and the LED works on the dimmer setting as well, although there is hardly any decrease in light. This is not an issue, as the 40 watt bulb at 1/2 power is still 20 watts and this bulb is closer to 4 watts at full bright. If reliability was not an issue, I would strongly recommend this LED replacement for GE Over the Range Microwave ovens for both the interior and exterior lights (GE MW model was JVM2052SNSS). Yours may be different as they used halogen bulbs in later models.
