Lxcom Lighting G4 LED Bulb 1W 12V LED Light Bulb T3 10W Halogen Replacement Bulb G4 Bi-Pin Base Warm White 3000k No Flicker for Landscape Lighting,10 Pack

The stated measurements are accurate, but this bulb is just a little larger than the original halogen bulb. Since the bulbs outer layer is a rubber material,I was able to push the globe over it anyway, but if you need an exact size for size replacement, this one may be a little large. The bulb quality is great and I am happy with the light output, so 5 stars.

This LED modules are practically a perfect replacement for a 10w incandescent. The light output appears almost the same but disbursed more evenly. In my pictures the fist has this LED installed in the left with an incandescent on the right, then each light individually. The last picture is with LED installed in both fixtures.

Couldn't find a 20W LED that fit in the small puck light. Took a chance on these and they fit perfectly. Plenty of under cabinet lighting for me. No more lava-hot halogen that were melting the pucks.

The media could not be loaded.  Finally found an led that could fit in my kitchen chandelier. These are nearly exact in size and the color is warm and even. So happy!Update: purchased at end of April. It’s now August and I’ve replaced 4 bulbs. They flicker (video) and then die. Less than 4 months and I’m losing bulbs, which is way below the lifespan expected from an LED.

I installed 12 of these bulbs in my deck lights and they looked fantastic when they worked. I run them about 4 hours every night. In the nine months that they were installed 10 out of 12 are now dead. They claim a 30,000 hour life. That may be true of the LED itself, but I suspect that the switch mode power supply which converts 12VAC to somethin like 1.2V DC to power the LED is failing.

I bought these in Mar 2020 and installed 12 bulbs. First one failed after a couple months. A couple more failed a month later. Now in Sep 2020, four more bulbs have failed. I'm guessing the electronics contained in the bulb are not a good design and causes the LED to burn out. I would not recommend these to anyone.

I put 20 of these bulbs in chandelier. Flickered badly enough to be unusable. I went back to Philips incandescents.

These G4 bulbs are just the right size to replace G4 12V 10W Halogen bulbs used in many Ikea under cabinet light pucks. These run a lot cooler and produce about the same amount of light and color temperature.
