Amazon Basics MR16 LED Light Bulb, 50 Watt Equivalent, Energy Efficient 7W, GU 5.3 Base, Warm White 3000K, Dimmable, 10,000 Hour Lifetime, 12V Low Voltage|6 Count (Pack of 4)

I have been waiting for LED MR16 bulbs to get cheap enough to make it worth while making the switch to LED. These dont quite dim as low as incondescent MR16s, but good enough. There are no LEDs that truly replicate the warmth of incondescent bulbs, but these still do a good job. They give off a warm light that is as good as it gets for LEDs. One note... you have to get a dimmer switch that is designed to work with LEDs. My old one did not work correctly with these bulbs. They flikered at full high, and would not completely shut off. Once I replaced the dimmer switch with LED dimmer, there was no more problems. They work great. And I would say that they are brighter than the 50W incondescents that they replaced. Well worth the money.

I've installed these in a kitchen track-lighting system. The light fixtures have rose-colored glass lampshades which are normally prettily lit by the semi-transparent reflector in a GU 5.3 halogen bulb. Firstly, these LED bulbs do not have a semi-transparent reflector, so the lampshade is dark, not lit. This was expected, based on the photos of the bulb. Secondly, these bulbs are slightly longer than halogens, thus protrude slightly from the lampshades. Therefore, they do not look quite as refined as a halogen bulb in this particular fixture. Also, this bulb is a little heavier than a halogen, so it might slip out of an old, worn fixture that relies on friction to hold the bulb by the 2 electrical pins. Thirdly, some of these bulbs have a random flicker when the dimmer is cranked all the way up. It's very weird because all 6 bulbs are on the same 12V DC dimmer, and not all of them flicker. Turning the dimmer down to the 3/4 position solves the flicker without much of an impact to the brightness. This may be due to older dimmer technology supplying more than 12V, which can cause the bulb to overheat and throttle back the brightness. Aside from these issues, the bulb design looks nicer than many others, they are plenty bright, have a wide and even light distribution, dim well enough, and the "Warm White" color is slightly whiter than the original halogen bulbs. Not bad, but not perfect.

Just received the six pack. I removed a halogen lamp from the spotlight in front of a tree in the front and replaced it with this one. The halogen was HOT!!! Waste of energy. This bulb is brighter. Doing a little math, this one bulb will save $9 in a year over the halogen one.

Bought 3 more boxes after changing out one of my track light strips, was very happy with the result, only negative at the time was no light filters through the backside of the bulb so the glass canopies do not “glow”. After receiving the next boxes, one bulb blew in a big flash when turning the fixture on, change bulb and all was ok. Move onto the next track light strip, all seems to go fine, fixture turns on, turn it off, now the entire strip is dead, did the bulbs just kill the transformer? The old MR16 bulbs are over 20 years old. The LED lasted minutes. Very disappointed and partially in the dark with no light.

I keep a string of bollard walk lights along my driveway and I assume the bulbs have a shorter life than if they were indoors. So, obviously, I need replacement bulbs periodically. These are awesome! The 3000K is neutral enough for me (prefer 4000K, though) and they are unexpectedly bright. Do not install bulbs at night; you will blind yourself for several seconds! I cannot evaluate the longevity, yet. Over time, I expect them to last as well as previous brands have.

Great bulb if they would last- nice looking, good wwhite. but 2 have failed in a year. SO much for LED longevity. They just blink on and off. Happens in the beginning when switched on so not a thermal problem. Bummer

I bought a set of these lights from a different vendor. They were a nice color and brightness. Of course, you can never find the same vendor again (not available any more) and so you end up buying what you think are the same lights. But unfortunately, they’re not quite the same color (a little more white), and therefore not quite the same brightness, and don’t dim the same way. This is no judgement on these lights which are fine in and of themselves, but it’s a judgement on the industry which can not get its act together by producing homogeneous lights.

I have tried a bunch of different LED MR16s over the last several years… most without success and most just aren’t bright enough and many are just not reliable. Longevity with a lot of them is frankly no more than halogen and sometimes they just do funny stuff…. Blinking, buzzing, etc. Which just defeats the purpose of paying for LEDs. I have probably used 25-35 of these Amazons MR16s so far (about a year into using them) and I have found them pretty solid (the best of have found so far). Brightness is better than many others I have used, I like the color temp and so far they have been pretty reliable. However, I just had my first bulb start blinking/flashing on occasion… sometimes it works, sometimes it started flashing on and off every few seconds. And I have been using it for probably less than a year. Personally, I have not found ANY MR16 LEDs that work without issues, but these are the best I have found so far with this level of brightness. So far I give them pretty solid rating, but if I see more failures, my rating will obviously go down.

We bought a house with these fixtures that require MR16 bulbs. Researched quite a bit and the upgrade is as simple as replacing the bulbs. The original Halogen bulbs are so hot and burns tons more energy. These new LEDs are not as warm but brighter in comparison. It's good to point out that while it's brighter, it is brighter when dimmed. Do wear gloves when replacing the bulbs because you'd need to pull quite hard. The halogen bulbs can burn your hands badly. Also prepare a garbage bag when you take out the cover because there would be dust and debris coming off from your ceiling.

Halogen light 12v transformer is not compatible with LED lights. It will cause LED lights to overheat, flicker or not working at all (may work at first and then fail). Do your self a favor by replacing the old transformer with LED compatible transformer. I learned this lesson after trying different brand of LED lights with the old transformer. Youtube has good info on this topic.

Good quality, great price. Only thing is I find that they are a more bright white then warm white.

They feel high quality. I replaced all the halogen pot lights with these along with smart Wi-Fi dimmers. Much brighter and run much cooler. Zero flickering and dimmable to 10%. All @ very good price. What else more can you ask for?

The lights are bright & white, but I wouldn't call them "warm". At least they didn't have a discernible blue cast to my eye. A much bigger problem is that they barely dim at all before turning completely off. I used them with a universal LED/Halogen/Incandescent dimmer switch from HomeSeer (WD100+), which is a high-quality product. Fine for use with an ordinary (non-dimmer) switch, though.
