I have ordered three of the lamps for the ceiling light in the kitchen and to very impressed. Similarly, bright as 75W bulbs (or perhaps 100W? I miss just the comparison). The light is quite warm, no artificial white light. I particularly like the large viewing angle, which makes it very similar to a conventional bulb.
Since the bulbs are with me for only two months of use, I can say nothing about the longevity. Abnormalities I will supply later here.
