TAIYALOOG4 LED Bulb JC Type Bi-Pin Base Light Bulbs 1.5W 12V AC/DC 10W T3 Halogen Bulb Replacement for Under Cabinet Puck Light, Chandeliers, Landscape Lighting, Warm White 3000K, 10 Pack

Update: They contacted me after posting this review and offered to send brighter replacements that were 1mm larger in diameter if that was acceptable. I agreed that the slight extra size would fit my holders and they sent them. The replacements were indeed brighter and equivalent in brightness to my prior 20W halogens. Therefore, I would recommend that if buying this type of LED for replacing under-cabinet halogens, you definitely go with the largest possible size that will fit within the holder. If you do that, I think you will be satisfied. Due to their customer service providing replacements and correcting the description from saying equivalent to 20W to a more appropriate 10W, I am updating the star rating on my original review below...If these had been just a little less bright than 20W halogens I would have been fine with that BUT they are a LOT less bright. Furthermore, I also compared them side-by-side with some 2W G4 LEDs we have in under-cabinet puck lighting and they're even less bright than those even though these are 3W LEDs.So... much less bright than our 20W halogens (despite claiming "Equivalent to 20W-25W G4 Halogen Bulb" at the time of purchase) and also less bright than our 2W G4 LEDS, even though these are consuming 50% more energy! In other words, no matter how you look at it, these are very disappointing.

Eight months later and all 28 bulbs I installed still work. None has gone out and there is no flickering. Time will tell how much longer they last. So far so good.Update - Shortly after posting the original review, I had a concern with a bulb. The customer service was excellent and very responsive. Within a couple of days, I received a replacement pack. Buy with confidence as they stand by their product and warranty,

I have no data on longevity, but I was delighted with the pack of lights when received. I needed one, ASAP for a light with a burned out halogen bulb. I ran it overnight and found the light housing to be much cooler than usual with this new LED light. The intensity was excellent, the light "temperature" rating of 3000 K seemed to be accurate. I would buy these again. The manufacturing quality seems to be very good. The distance between the pins was exactly 4 mm, and it fit just fine in the light fixture.

The description says dimmable but they don’t work with standard furniture 3 level touch lights.

Product is exactly what I looking for. I will reorder another set.Thanks.

Very pleased with this purchase. Installed in under cabinet lighting to replace 20W halogens.

Sick and tired of replacing Halogen bulbs in my landscape lights that last less than a year. This 10 pack of LEDs cost what 2 halogens go for in the big box home stores, so a great value. These were only slightly taller than the halogens that they replaced, and still had plenty of room in my landscape lights. Nice warm color that matched perfectly with the halogen bulb right next it, and just the right lumens output. With these you don't have to worry about getting finger oils on the glass causing premature burnout like in halogens, plus these aren't even glass, but a soft, flexible plastic. Can't wait for my other halogens to burnout, so I can replace them with these. Let's just hope they last a lot longer than the halogens.

Actually I ordered these tiny bulbs because they put out less light that my previous bulbs in those fixtures. I am using them in landscape lighting fixtures that wash up a blank white wall at the side of my house. There are no architectural features there that deserve highlighting. So these will just provide a softly diffused glow on the wall in front of which will be silhouetted the shrubs planted there.My previous bulbs were rated at 2 watts each. These being rated at 1.5 watts each should reduce the overall brightness by about 25% resulting is less of a bright, white glare.For what it is worth, my wife thought these tiny, little boxes containing these bulbs were "so cute" that I almost expected her to want to be the little boxes on display!
