I replaced several outdoor 12v halogen lamps with the 18 smd warm white leds. I installed the last four on May 14th and one has failed already after just two weeks. To be fair I have not yet contacted led wholesalers to see if they will replace it. I did expect much more use before failure.
I got these to replace 6 halogen lights in a fixture over my dining table. They replace 20W halogen bulbs, for only 2.6 watts. Thats 1/10 of the power. At 216 Lumens Compared to the 300 of a halogen, the resulting light loss was hardly noticeable to me. They are definitely a whiter light than the more orange halogen that it replaced. If you follow the $1/watt/year estimation for the cost of electricity, these will save me 17.4 watts per light, so $104.4 for the year. Paying for themselves in under a year in energy savings.
