G4 LED Bulb 3Watt led Halogen Replacement 12V AC/DC,2700K Warm White Light Dimmable, led Replacement for Halogen Bulb 30W 6Pack (3Watt)

I have these as landscape (path) lights for about 3 years now. The color, brightness, life has been great. Zero failures. They are a little bit taller than the 20W G4 halogen bulbs which came with the lights.I just purchased the 4W for some additional lights, and, sadly, it appears they are discontinued. I hope that they bring them back. I also have the 5W ones, and they are great, too.I have not had the failures or problems that others have. I run my landscape lighting at 12V (not 15V).

I use these in puck light for under cabinet lighting that used halogen bulbs. They barely fit the fixture. I had to put them in at an angle to get them to fit. Actually the very end of the tip of the bulb is touching the side of the housing above the bulb but work fine. They do have a plastic type coating on them so I'm really not concerned about that. They're definitely brighter than the original bulbs. I can tell you that an incandescent type dimmer will not work. I purchased the Lutron Skylark dimmer for LED's This has a separate range setting on the side of the switch for different dimming options depending on your fixture. Even with that at the lowest setting the lowest they dim to is around 50% brightness which is fine for my application without any flickering.

Used 8 of these in cabinet puck lights replacing dimmable halogens. These do dim, but they blink at various brightness levels. I didn’t have this issue with Feit LED bulbs purchased at Home Depot.

Bought these as advertised at 5w to be brighter than my current 3W. But testing on the bench with DC supply shows they only pull 3W. Viewing them installed, they are quite a bit whiter than my 2700K lamps which is this products stated color temp. the box the bulb is packaged in has check boxes to indicate wattage, color temp, etc. but none are checked, and bulb is unmarked. So who knows what the specs are for what was delivered. Gave 2 star because they seem well made.

If you are looking for LED replacements for under-counter halogen bulbs, these will fit! Most LED replacement bulbs are about a quarter to a half inch too big for many under-counter lights (most of the bulbs sold on Amazon will helpfully have the dimensions--look at them carefully!). These are very close to the size of the actual halogen bulbs, perhaps an eighth of an inch longer, and they fit in my small round under-counter fixtures. The light is very nice--warm, bright but not harsh. Highly recommend.

I used these for a light fixture for my Mother's dining room. They work great.Only negative thing I would say is, one of them burnt out. and they don't have a huge range of dimming, but that might have as much to do with my dimmer than the bulbs.

I have purchased many of these bulbs and unfortunately many were defective and began to strobe or burn out after just a few days. In addition, there were significant color variations within each individual order. I had been returning these to Amazon for refunds but eventually contacted the seller asking if they were aware of these issues. Seller asked me to send photos which I did. Then I was told because Amazon fulfilled the order they wanted nothing to do with it. No very good customer service, but still no big deal because Amazon was giving me refunds. Bulbs continued to burn out and then today one caught fire. It was lucky I was home other wise the fire might have spread. The whole room filled with smoke. See the photo. These bulbs are dangerous and therefore I cannot recommend them. I pulled everyone of them out of my fixtures. I also reported the fire to Amazon in the hope they will investigate and pull the product.

I replaced all of my Quartz Halogen bulbs in my RV. Over 50 of the these particular bulbs. The color rendition is reasonable but varies a bit from one bulb to the next as does brightness, but in general they are acceptable and much safer and economical then the Quartz bulbs we replaced. Over the past 2 years I placed 5 orders. The bulbs began failing as soon as 2 months after installation. Presently, I have 26 failed bulbs as shown in the attached photo. I would like to request the company replace them as none of even the most recent failures have more than a small fraction of the stated 20,000 hour lifetime but cannot seem to find a way to contact them.
