SUNTHIN 10 Pack Dimmable GU10 LED Light Bulbs for Track and Landscape Lighting, with 38 Degree Spotlight Bulb and 500lm Output, 60W Halogen Replacement, ETL Listed

I'm not usually one to gush over products purchased on Amazon. In fact, I rarely rate products at all. Most of them do what I expect, some are just OK, but expected for the price paid, and a small percentage get returned when they don't work as described (or don't work at all). But these bulbs really outperformed my expectations.In the mid 2000s I finished my basement, and lit two rooms using an array of GU-10 fixtures purchased at one of the big box home stores (they were inexpensive and I liked the way they looked). I didn't really think about energy usage, even though at the time I had been swapping out our incandescent bulbs in all our other fixtures for CFLs. Each fixture used a 50W halogen bulb, which gave me a total of 500-600 watts per room. Considering the rooms weren't all that large, that seemed excessive, and I began regretting my choice, especially when my kids would leave the lights on for hours or days at a time (since it was the basement, we didn't always notice). A year or two ago I purchased a few GU10 LEDs during one of Amazon's lightning deals, but I didn't notice that they were a much cooler color and really didn't go with the room.Fast forward to a few days ago when I started looking again. I found these bulbs that were actually less expensive per bulb than the lightning deal LEDs I bought a couple of years ago, and purchased a few boxes. Well, was I pleasantly surprised! Not only did the bulbs fit the fixtures perfectly and put off very little heat (expected with LEDs, but some LED bulbs put off more heat than they should, even those purchased at warehouse clubs), but they actually put out more light than the 50W halogens that were originally in there. Now, I didn't measure the light output, so I don't know if they're putting out exactly 500LM per bulb, but they've got to be close. Not only that, but they worked beautifully with two different types of dimmers: one Leviton dimmer designed for incandescents, and a much newer FEIT dimmer (purchased from a warehouse club) that is designed specifically for LEDs. No flickering, and they dim down almost to nothing before going off. And I'm now only using 65-77 watts per room, assuming full brightness.Now obviously I can't rate the longevity based on a recent purchase, so that will have to wait for a future update. But these are definitely highly recommended!

so far, the LEDs work well as replacement GU20 bulbs from former halogen/xenon. the warm variety most closely resembles the former hue at full lighting. like all LEDs that I know, they do not dim to an amber-ish hue like halogen/Xenon, and they also do not dim as much in brightness, so expect that if you're transitioning bulbs in a room. I still have half the switch on former halogen/xenon, and the swith now buzzes/hums in dimming positions. I'll report if the single pole dimmer switch continues to function when I transition all bulbs over to these sunthin LEDs. different mfgr on a different 3-wayswitch in home requires enough noise on the circuit that I had to keep a halogen or incandecent inline. Overall: happy so far with color, function & company.

We’ve tried to find LEDs to replace our halogen bulbs for years, with nothing quite working. These are excellent! They are bright at full blast, which makes it easy to use the kitchen. They dimmed further than I anticipated, creating a low warm atmosphere for late at night or early mornings. Only issue is turning them on when dimmed, you have to turn them up for the bulbs to turn on and then dim them back down. But I believe that’s to be expected with LEDs. The color is perfect. Feels like incandescent lighting without replacing bulbs every few months (or days it seems).

The bulbs are not warm in tone. They seem well constructed and all worked, just should not have warm in the title at all

I guess I didn't read the product description fully about compatible dimmer switches but I just got my Maxcio smart dimmer switch installed and found that the bulbs have a pretty awful flicker which gets worse at lower brightness levels. I can't knock these bulbs completely as I'm not entirely sure if it might be my switch or the power to my house. The bulbs worked awesome otherwise before I started dimming them and I'm just outside of return date so I'm going to keep them but not use them as dimmable bulbs. They out perform the output of the halogens we had and are similar in color which I like. They're much cooler to the touch which makes me think it's going to help my energy bill in more than one way! I feel bad giving them 4 stars but the flickering is super annoying. I'll change it to 5 stars once I rule out my switch and power source by purchasing a different bulb.

So far, so good for these bulbs. installed 9 of these in track lighting in my living room to replace old 50 watt halogens. Also installed a Smart Dimmer switch by Martin Jerry so I could control all of it via google home. Initially I was concerned about the pair and possible flickering of the bulbs, but this combo works great and I can dim all the way down to 2% with no flickering. The bulbs are functioning great and can get really bright when turned all the way up - much brighter than the 12 50w halogens I was using before. We'll see how they are for longevity and I'll update if I have any failures.

I bought these bulbs a year or so ago and they were fantastic. I wanted more but they were unavailable for a while. The new ones are now the horrible cold bright white light of every other led bulb. I’m really disappointed in the change. Back to my never ending search for an LED that’s ACTUALLY A WARM WHITE.

I've tried other inexpensive GU-10 LED bulbs and found that they had a very short lifespan. I was leery of the Sunthin bulbs because of the low cost, but I'm very glad I tried them. We've had our first set in use for about 8-10 months and they're all still working, so we just bought a second batch to switch all of our kitchen and living room bulbs to the Sunthins. My wife is very happy with the warmth of the light, and I'm very happy with the much lower electric bill.
