G8 LED Bulb Dimmable, 20W Halogen Equivalent, 120V T4 JCD Type Bi-Pin G8 Base, Warm White 3000K (6 Pack)

I have searched for LED replacement bulbs (instead of the original halogen bulbs) for my under cabinet puck lights, for a long time! First I ordered these. https://www.amazon.com/gp/product/B07PPFG3CL/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1. They were thicker and had a rounder design that fit, but wouldn't allow me to use the glass lense covers. I will be returning them. They were the Daylight White color and I really didn't care for the cool/cold intensity or tone of that style.Then I found and ordered these and my seathe was finally over! No more dark areas on my kitchen countertops! At first, I didn't think this flatter style was going to work because the first one I installed only worked for a few minutes, then just dimly flickered. I got a response from customer service a few hours after I reached out via the email address on the front of the package of bulbs. Then I tried another one from the same package and it worked perfectly! I replaced all the remaining bulbs except one as instructed and all the bulbs worked fine and we're compatible with my dimmer. I contacted customer service again to inform them that my problem turned out to be a faulty bulb. I asked for a replacement for the defective bulb. I also asked if I needed to return the bulb. Lily told me that wouldn't be necessary and she would send another package of bulbs. They arrived a few days later!I purchased the soft/warm white and I like it much better than the original warm halogen lighting. It is a little cooler tone, but brighter and still soft. It is pleasant and I really like it! It has been a pleasure doing business with this company, as it is obviously very important to them to please their customers. I couldn't be happier with the finished effect!

UPDATE: 11/11/2020I have updated my review form 1 star to 5 stars. As I noted below I really liked the bulbs but was frustrated with several bulbs failing quickly. I responded to the seller using the email provided with the bulbs. They very quickly and politely responded to me. As they indicated below they did indeed quickly replace the bulbs that had failed. They indicated that they have a new remanufactured bulb product with improved performance and reliability. I have replaced the problem bulbs and so far after a couple of weeks they are all functioning great.Wonderful customer service! I will come back and update later if anything changes.................................................................................................................................................................I liked these bulbs initially but have had nothing but problem. They look great for about a month or two...and then they start either flickering on and off...or dimming to where they are just barely glowing. Replaced with new bulbs and exact same thing happened.

I bought these bulbs to replace the old Xenon G8 bulbs in my fixtures. These fit perfectly, and the light output is bright and good color. The advantage is that they do not get at hot as the Xenon bulb and use much less electricity.. I assume since they are LED they will last a very long time also.The only issue with the bulb is that on the "dim" setting they make a very slightly detectable flickering. On the "bright" setting on my fixture, no flickering. Their customer service is VERY RESPONSIVE and explained why, although I do not think the "dim" setting flickering will be fixed. They said to leave one Xenon bulb in the fixture as a possible fix. I plan to do that in the future but I will leave my fixture on "bright" setting and they work just fine.Another item to look at is their "disk shaped" bulb with all the LED's one one side. Ive tried these and will be my go-to replacement in the future. All the light is directed downward, as you want in an under-counter fixture and they are so small they fit fine in the sockets.Summary: excellent quality and customer service. 5 stars except for technical issue but not a stopper on bright setting.

UPDATE (6 weeks after original review): All of the bulbs have now failed. These are junk; avoid them.UPDATE (two weeks after original review): Three of these lights have now failed. I have one spare left; fingers are crossed. Lowered to 2 stars.Original Review:I have these installed in those little puck lights that normally take halogen bulbs. The first one I installed looked great - nice and bright, though a little cooler than the halogen. I have some photography gels to warm it up a bit.The second one was a dud - would not light up at all.The third one was...finicky. It would only light up half of the LEDs until I jiggled it into the magic position. Maybe the pins are slightly too small in diameter so it didn't get a solid connection? In any case I found the magic position and both pucks were nice and bright.Until a few days ago when suddenly the 2nd puck was at like 1/3 brightness. I shook my head and resolved to investigate it later. Except later - by about 2 hours - the puck was back to full brightness (I did not observe its behavior in the meantime). Then the other day *both* pucks were at reduced brightness for a short bit. Tapping one of the pucks (the outer shell, not the bulb) caused it to brighten up.So it seems like I may have to do some fiddling and maybe some slight pin-bending to make sure there is solid contact, though with the minimal current these should require I'm surprised they are so touchy. I am glad I still have a few extras as I'm not very optimistic about their longevity.
