XRZTG8 T4 LED Bulbs 120V 20W-35W Halogen Replacement Warm White 3000K for Kitchen, Under-Cabinet and Puck Lighting, Pack of 5

These led lights arrived in a five pack and very well protected from the shipping process. However the performance of these lights is still being evaluated. So far the first one I installed has already failed. We are on our 2nd of the five working now. I suspect this 2nd one and the rest will perform like the first one and not live long at all. First off the description says these lights are dimmable. They do operated in the night light dimmable setting of my microwave oven. However in my oven they do flicker a bit in the night light mode of my oven. They also flash when closing the microwave door which leads me to believe that these bulbs might not be the best match for my oven. What I mean is it may not be the lights that is the problem. My oven at this time works better with the halogen lights. The led lights may one day work as well in my oven as the halogen lights do but I don't think they ever will or need to. The GE microwave is no different as any other GE product. It probably won't be long before it fails and I will be forced to buy a newer model that already has LED lights in it that it was designed to work with. The Volts and current of the oven circuitry will be designed to work with the modern LED lights we have available today. I estimate these lights will fail after a month of service in my MW oven. The halogen type last at least a year or two in my MW oven. Or maybe a person reading this will have a suggestion to try. I know I haven't mentioned what model MW oven I have, as I don't feel like getting up and checking it right now. I can get it if someone would like to know. I will end with this. Buyer beware and do the research as best as you can and decide for yourself if these lights will work well in your device. Update 10/15/20 The second led light has failed in my device which is the light underneath my GE Microwave/Convection oven. I believe that it is my device that is the problem. The LED lights do work and are will dim when the oven switch is set to dim. But electrically they are not a good match to my oven. It is my guess that in the dim mode my oven is sending voltage and current that is not enough for the LED. I am now on my third of the five in the pack. Update 10-25-2020. These fit fine in my fixture on the bottom of my GE Microwave. However they are not a good match electricly. My fixture has an issue with its electric circuit and will provide voltage when the switch is off and close the microwave door. I just replaced it again. I love the light these bulbs provide, but they will not last more that a month or two in my fixture.

I had high hopes for these bulbs. They are brighter than most, use little energy (assuming one can believe the product description) and fit in the puck under my kitchen cabinets, though I had to leave the puck lens out. That is OK since the bulbs have their own plastic cover. If only the bulbs would last as long as a typical LED, these would be at least four star. Sadly, with daily use averaging less than two hours, the originals started flashing and dimming within eight months. To their credit, the seller replaced the bulbs under warranty, but the new ones are even worse quality than the originals. It has been less than two years and all of the 10 bulbs have either burned out or are blinking. The manufacturer seriously needs to improve its quality to have a usable product.

I usually don't have time to leave reviews, but this time it will be worth it. I am very picky about light quality as I have done showroom display lighting and interior design. The light bulbs can make or kill a space. The right light enhances furniture colors. Cheap/Low quality bulbs will not reflect the true colors in your room. It can also tire our eyes. Almost all my light switches have dimmer so I can create the right ambience. Also amber light is good at night when you go to the bathroom since it won't full wake you up. I had been looking for a halogen alternative for a while and I tried this one out. It is perfect. It has the right light color (2700-2800k) and gives a good color reflection. I was also looking for 20W halogen alternative, and these are actually better. They are more like a 35W halogen so it is perfect when using on dimmers since I can bright it very low or get a lot more light when needed. Because it is LED, it won't be a problem with the fixture wattage limit. Thank you for producing a good produce.

This type of base is most often found in appliances where there are high vibrations. My use is for the lights in the underside of an Over the Range Microwave. That means there's a lot of vibration from the fan and slamming the microwave door. The light is a good color…I recommend the daylight color over soft white but they don’t last long, 6 to 9 months if you’re a heavy duty microwave use. But they’re cost effective and superior to incandescent bulbs.

The original halogen bulbs on the bottom of my GE microwave are very dim, and I purchased these led bulbs as a replacement.The tapered bottom and pins, and the length of the new bulbs fit into the sockets of the microwave perfectly. I have a lot more light and the color temperature of the bulbs are perfect. I do see a very slight flicker when I have the light switch in the DIM position, however I always use the high light setting because I needed more light in the first place. I love these bulbs. UPDATE Having used these for some time, the bulbs don't last that long. After a few months they fluctuate between bright and dim and the clear housing on it comes loose. I still like these bulbs but I have to give them a lower rating because they don't last that long but they're my only option.

Previous Chinese LEDs that I have gotten have had a poor track record - the worst were a set that had an average life span of 45 minutes. But these have been in place for over a month, replacing the xenons in our under cabinet lighting. Since they are so much cooler and more efficient, we use those lights much more. They are also much brighter, and when the fixtures are set to low, the LEDs flicker. But I have found that to be the case wherever I have put LEDs and there is only low and high. Fortunately I also had a dimmer installed for the under cabinet lights, but it was very old and sometimes had odd results. So I got a smart dimmer, and now the LEDs dim and brighten perfectly, and I can control them with my Echo Dot. Nice!
