MASTERY MARTGU10 LED Bulbs Dimmable, 50 Watt Halogen Equivalent, 2700K Soft White, 4.5W Flood Light Bulbs, MR16 Spot 400lm 40° Beam Angle for Recessed Track Lighting, 10 Pack

These are a great, energy-efficient replacement for traditional halogen GU10 bulbs. They are significantly brighter with a much wider throw angle, so they provide quite a bit more light per fixture. We regularly keep ours dimmed to about 75% because they’re so bright. Even though they are listed as 2700k, they feel more like bright white than the halogen alternative. At full brightness there is not a noticeable difference, but at the dimmest settings halogens turn a warm orange color, while these stay the same soft white all the way down.My fixtures have a frosted glass housing, so I’ve spent a lot of time looking for an LED option that would throw a little light to the side and illuminate the housing. The glass casing on these does allow a little light to reflect back along the sides, and in my fixtures the frosted glass glows slightly, but it’s nothing like the original halogen bulbs that provide a bright hot spot on the side. I don’t think there’s an LED GU10 out there that will look just like halogens in a frosted fixture, but these are the best option I’ve found.

The media could not be loaded.  We originally bought 5000k dimmable from another brand were too white for our liking (did not dim to zero ), so we bought this Pack of 10, 2700K Soft White which looks like halogen yellow tint almost exactly (fooled my daughter when they were side by side lit) . They are as close to my original halogens as I could expect and dimmed all the way down to zero. no buzzing or flicker that i could see. Pardon the noise in the background daughter in the other room with hair dryer haaa. only had them a few days no problems. will update if i do have any issues. Some dimmer switches dont go to zero including mine but these bulbs will likely dim down to zero with any dimmer switch. also some dimmers are adjustable under the cover plate see pictures (this is the switch i have). I'm a contractor/ electrician +.

Nice color. Works well in ceiling fan and dining room table lights facing down

Really like these bulbs. I bought and tested 4 different GU10 LED bulbs on Amazon and these are the best overall. Good, even cast, accurate color (i bought the 2700k version), no loud buzz, dims to practically zero with Lutron Diva dimmer. Size and design most closely matches traditional halogen bulb as well which helps with compatibility. And to top it off, the price is pretty good to. My new favorite bulb and has de-throned Hyperikon in my view. Hyperikons have very similar color, but the new ones don't dim quite as well and have a little more buzz.

We were cautioned about the "rim" of the bulbs potentially overlapping the surface of the installation on a range hood. That did not happen and they fit nicely. Dimmable. They are brighter than the original bulbs even at the lowest setting, and not quite as "warm" a light. Of course no one could rate "longevity" just after purchase, and I don't know why they would include that as a category, but until we find out otherwise, we will assume LED's last a long time. We'll see.

These lights are nice and bright. The light is a very bright white, almost like being out in direct sunlight, but no signs of yellow. I only use them on the high setting on my range hood because the low setting flickers. Getting the old lights out was challenging because of their flush mounting, how tight they are in, and how much grease had accumulated over the years. I needed a special suction-cup lightbulb changer to help get the job done.

No window kitchen. Incandescent and flourescent lights don't cut it. Got these bulbs today for track lights in my kitchen. I have two tracks which were not helpful. I installed three of these bulbs in the three bulb track and it all came to life. I can see what is on my stovetop now. I will install remaining 7 bulbs on the other track and expect to have to use the dimmer switch. Light is crisp, bright, and daylight. The vendor includes a url address to register one's purchase! I have read reviews which say that the vendor is very responsive.

We have halogen lighting in our kitchen and I just could not tolerate the heat they gave off any more. We had tried a different type of LEDs from a big box store a couple of years ago, but the sides were opaque and looked ugly in this particular light fixture. I decided to try again in 2020 to see if anyone had produced a better solution, found these, and ordered these new LEDs that are surprisingly wonderful. The sides are see-through when the light is on and look nice in the sockets (see photo), the lights are almost as bright as the halogens and I can actually can see and read better with these LEDs, and the dimmer function works. The best part of all is that I'm not sweating as much while I'm cooking and we no longer have to dim the halogen lights to half their wattage and turn up the AC to cool off the room. I cannot give a review on their longevity, since I just purchased them, but so far I am very pleased with this purchase. They come well-packed, and my order arrived very promptly. A huge "Thank you!" to the manufacturer, the seller, and the shipper.

The media could not be loaded.  These lights are priced just right! FULLY DIMMABLE. I got the soft white 2700K bulbs to go with the rest of my apartment. Looks good!Payed a little under 60$ for 12 (2x 6packs) and they came much before the delivery date.Old lights were halogen. The bulbs being used in my potlights were 50W or 35W bulbs. After my calculation, I just cut my hydro bill for lights by 90%. This will save me hundreds of dollars during the year.If you're looking for bulbs on a budget that will help you cut costs and beautify your space, buy these bulbs now!

These lights do exactly what you'd expect for a decent price. Bright, efficient, exact replacements for GU10 tungsten bulbs. Pop them in with a push & twist, turn them on, see things.I have a teensy issue with dimmer compatibility and flicker but that seems to be the Achilles heel of LED based lamps in general and we're all probably used to that by now. These ones are better than average in that regard.

I noticed that the light coming from my Philips halogen bulbs had "yellowed" over time. I use the bulbs to illuminate a picture and need a more "neutral" white for truer colour representation. I wanted the brightness to match a chandelier on the same dimmer circuit and the colour temperature to be harmonious with my other halogen lamps in the room (Reference bulb: Radium Skylight, 12V, 50W). I have included pictures using a Mastery Mart bulb 2700K to light 1/2 of the picture and my reference light the other half (more or less). The light fixture holding the Mastery bulb is on the ceiling and not in frame of the photo. In the second photo I use a Dewenwils 3000K vs my reference light. To my eye the 3000K is too white / gray when compared to the reference light.The Dewenwils is a very fine bulb, especially the 400LM as it illuminates the back of the light fixture very much like a true MR16 bulb, has excellent dimmer performance, great dimmer range, and completely flicker free (on my old school circa 1978 dimmer switch). The Mastery bulb is excellent in most of these categories as well, but boasts lesser wattage and higher life expectancy. But the clincher was the 2700K of the Mastery bulb, it is more harmonious with my existing lighting.

I got these to replace the halogen bulbs in my living room and kitchen pot lights. Their colour temperature (I got the 2700k version) matches the halogens quite well. I paired them with a Wemo dimmer, and at their lowest, they're almost as bright as the halogens were when switched on (without the dimmer) - at their brightest, they appear to produce considerably more light. I feel that they could be dimmer at their lowest setting, but I can't necessarily complain here, since there's no proper way to compare. Overall, can definitely recommend them - will update this review if I run into any issues/concerns!**EDIT (2018-12-15)**: So far, I've had 2 bulbs fail on me.**EDIT (2019-03-02)**: The Mastery Mart customer service reached out and offered a replacement. Very impressed by the support - I definitely encourage anyone having troubles to reach out to them!

We had stuck with halogens for probably longer than we should've for our track lighting, but as we change our households lighting to LED one by one it was a eventual changeover. The price for LEDs have become very competitive as in the past there was quite a big price gap and more incentive to stay with halogens. I'll stress that the competitive price point seems to be inclusive to brands such as these on Amazon, as I couldn't find anything this affordable at say Canadian Tire. These were slated to replace our 50W halogen bulbs, and thus far they are doing a tremendous job.The aesthetics of the light produced is a bit different, not as sharp and cutting but more of a glow and spread - we quite like it. Aside from the energy savings, it's also not volcano hot and it's supposed to last a lot longer - the halogens we have seemed to need replacing very often.  Also worth noting that they Energy Star and UL certified. If it does as it says, it will likely outlast our tracking lighting itself.The set came very fast and very well packaged. So much so that I thought it warranted a picture shoutout. Sometimes you get things from off brands here and it comes in the most questionable of presentation, but this felt professional grade. The lights themselves feel solid too, so far we're very pleased - bright, comfortable, no lag, flickering or buzzing of any kind.
