I was looking for an LED lamp which lights up all around, while also making a pleasant light. Round brilliant is because I want to use the lamp as a substitute in a ceiling light. I had previously installed an LED lamp, which had only 160 degree beam angle. That looks very unsightly, not for the entire lampshade is illuminated. This LED lamp is the illumination of the entire Screen no problem.
Pro: very bright pleasant warm light (subjectively) no humming very good all-round illumination
Cons: so far nothing, but may vary.
Since I have the lamp only just used of course I can not make any statements about the durability. Should something arise, I'll resent that at this point.
