Obsessed with some other LEDs, which I have also purchased from Amazon, I tried it again with this one. They are bright as verprochen, one has a clear light, not the least bit diffuse. Unfortunately, it's freezing cold white - as you might expect in a laboratory. Retrieved from "warm white" can be no question.
If you need only good view of the work, these lamps are exactly right. However, it should be clear that they do not allow any "feel good" atmosphere. for the living room, for example, they would be an impertinence.
There inzwsichen other LEDs that produce a pleasant living light.
