TAIYALOO GY6.35 LED Bulb 5W Equivalent to 50W Bi-pin Base Halogen Bulb, AC/DC 12V Warm White 3000K for Pendant Light, Chandelier, Desk Light, Accent Lights, Landscape Lighting, Non-Dimmable (4 Pack)

Moved to this home in nearly 3 years ago. House and fixtures are from 2005. There are 6 pendant lamps matching those in another review on this page. Bulbs were 35w 12 volt halogen. Replacement with LEDs became imperative because the heat generated by the halogens was gradually deforming the metal contacts within the porcelain bulb sockets. Two of our 6 lamps already were intermittently going dead. Tried a variety of 12v LED bulbs from various sources. None of them filled the glass globes evenly while still directing enough light downward. These bulbs do. Thanks to Evan Sermos, Jr. for his review and photo! Compared to the native 35w halogens, these produce very slightly less illumination, not enough to notice unless comparing simultaneously. White balance is good, likely close to the claimed 3000K. CRI is fine, with good rendition of reds and of fruit colors. They dim smoothly from our wall switch without flicker. Since they do not produce intense heat the sockets are working properly. Follow-up: After 4 months one bulb failed. Since I had extra bulbs from the original order I replaced it. Then I wrote the seller via Amazon and immediately a replacement package of 4 more bulbs was sent. Spo the bulbs are pretty good, and it pays to shop at Amazon. The seller, TAIYALOO, represented by Cherry was excellent. When UPS lost this replacement package, she quickly send another via USPS and it was delivered in 3 days.

I ordered these LED bulbs for a desk lamp, to replace the original 12V Halogen bulb with an LED. The package arrived quickly and the fitting was GY6.35 as specified. However, because the base of the LED bulb is circular (and the GY6.35 Halogen bulb has a flat base), the LED did not fit in the desk lamp. I wrote to the seller (email details and a request for feedback in case of any issues were included on the package) and received an immediate response. Seller offered to replace the bulb with a smaller LED with the same specs (i.e. 12V, GY6.35 base) but smaller brightness (the bulb I ordered originally was a 50W equivalent; the smaller one is a 35W equivalent). A package of 6 replacement bulbs arrived (free of charge) a day after I confirmed my interest in this replacement. The smaller bulb fits my lamp perfectly and provides more than enough light. The moral of this story: check the drawings with bulb sizing provided with the product images, and make sure to order a bulb that fits your lamp. The second take away is that customer service is not dead after all; seller did an awesome job solving my issue, even though it was of my own making.

I got a pack of these LED bulbs, deployed one and loved it; you can see my original 5-star review, posted Feb. 1, 2020, below. Sadly now, in April 2021, 15 months later, I join the ranks of the many reviewers here experiencing first flickering, and very quickly then substantial bulb failure, getting under 10% of the expected bulb life on this one bulb. However, the great news is that Sunaifa, the seller, just immediately sent me a whole, second, replacement pack of these bulbs AND refunded all my money, if you can believe it. Wow! Just the very best customer service! I’m a big believer that the really best customer service is that which isn’t needed - but if you need it, it doesn’t hardly get any better than this. I can’t continue to rate these bulbs 5 stars, since I’m not sure at this point about their longevity, can’t exactly recommend them. But they are very nifty bulbs while they last, and, again, the service is just fantastic. So now 4 stars. —— here below is my original 5-star review of these LED bulbs —— —— from February 2020, 15 months ago —— Great bulbs, at least for me. Compared to the 12v, 50w halogen bulb that this LED replaced, this LED uses only 1/10th the power, but yields 10% more lumens (light output), runs comfortably warm instead of hellishly hot, and doesn’t threaten to explode if touched. And I haven’t seen any flickering. On the other hand, this LED is about twice the diameter and 5x the weight of the halogen bulb, in case that matters to you. An easy 5 stars from me.

The bulbs are great. They are larger than the halogens they replaced but do the job perfectly. On top of that, the seller was SUPER RESPONSIVE AND HELPFUL! I had some problems with the bulbs flickering. The lights they went into are almost 20 years old, and the transformer feeding them was never designed to supply bulbs with low current needs (the old bulbs were 50W halogen bulbs). After a few emails back and forth with the seller, I finally decided to pick up a couple of these transformers: https://www.amazon.com/gp/product/B08YDCL87G/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&th=1 which comfortably fit within the housing and completely solved the flickering issues. Highly recommended!

If it wasn't for Cherry in customer service and her willingness to stand behind this product, it would have been two star instead of three. She sent me replacement packs twice when these bulbs kept burning out prematurely, but they never lasted. I loved the color and the brightness, but they only lasted anywhere from several weeks to a few months in a pendulum light over my kitchen sink (there is a glass cover surrounding the bulb). I do leave that bulb on nearly 24/7, but for comparison, the halogen bulb I bought these to replace lasted about two years. LEDs are supposed to last longer than that. I think they would have kept sending me replacements, which is great, but this bulb is time consuming to replace. I don't want to do that every couple of months. Once my replacement bulbs are all used up, I'm just going to try my luck with another brand.

The halogen bulbs in our pendant lights were very hot and burned out frequently. Recently I had to have the bulb holder in one of the lamps replaced because it no longer worked, which I attributed to the heat. I started reading about LED replacement bulbs for 12V 2-pin lamps, and noted that one of the sellers said that the LEDs I was interested in weren’t dimmable, and would flicker if used with a dimmer switch and that the only way to fix that was to replace the switch with a regular, non-dimming switch. However, one user said in a review that he had no problem with flicker, so I thought I’d give these a shot and replace the switch if I had to. Once I installed these bulbs I pushed the slider up to high and turned them on. At first they were fine, then a barely-perceptible flicker started. I pushed the slider down a bit and the flicker turned into a blink. I pushed the slider up to high and went back to my computer to shop for rocker switches. When I came back, the flicker was gone. After a while it came back, but it’s really not noticeable unless you’re looking right at the light (which I don’t normally do). They aren’t quite as bright as the LEDs they replaced, but close enough and the color is good. I’ll give them a little more time before I spring for a rocker switch. UPDATE 02.27.23 The flicker was perceptible from time to time, so I installed a rocker switch and that helped. However, shortly after I did that the transformer failed and I had to replace it. The new one looks just like the old one, but it is marked for use with LEDs which the old one was not. I have had no issues with the bulbs since.

UPDATE 2: I have gone through SIX of these bulbs in the last 3 years. they all fail at the exact same spot. do not waste your money ------------ Update: they sent me a replacement set. I have now burned through FOUR of these bulbs in two years. I thought LEDs were supposed to last 25 years. the future is not here --------------- I Bought these less than a year ago and they have already started to flicker and go out.

Got these to replace halogen bulbs in small pendant lights over dining room table. The halogen bulbs would burn out or fail fairly quickly I believe due to excessive heat. These bulbs match the brightness and color exactly. They produce relatively little heat The diffusers that went over the halogen bulbs would not fit over these but they are not necessary. They look fine in the fixtures, the light is uniform with no bright spots. They are obviously much more efficient and should last a long time. I highly recommend these
