The brightness is good, a 50W halogen spot at least equal, if not even a little brighter. The wide viewing angle ensures a few shadows or the famous "halos", very even light in the room. Only the light color is everything, but not a warm white. If one excludes that the bulbs have not been delivered by mistake wrong times - on the individual packaging was "warm white", they would therefore have been already packaged incorrectly - similar to the color of light very strongly the typical fluorescent tube. So in about the wish which sell a popular LCD TVs with LED lighting as a neutral white. If on the package "cold white" (cw) stood and I would purchase as I say "Respect, made clean." So the manufacturer needs almost certainly a clever colorimeter to the light color to be measured. Because his is defective.
