Blackened after one month
Reviewed in the United States on April 3, 2019
These bulbs looked great, and I really wanted to like them. However, after using one for one month in a desk lamp it blackened significantly, to the point that I was afraid it would burn soon, so I put it away. I noticed that a second one, which I used for a few hours to test a lamp, also had a slight yellow tint after that (see attached image for reference). Are all these bulbs supposed to be like that, or was this just a bad batch that I got by chance? Is it possible to have a replacement from the vendor? They seemed to have a great customer service.
