I can only confirm that this LED lamps is top notch. Absolutely suited for living rooms. Fantastic color of light, convincing brightness, in a price range, in which otherwise such performance can not be expected - in this, at least obvious - quality workmanship. The heat dissipation seems to have been carried out properly. Despite the much higher light output of the base is not felt warmer than those of base lamps with 60W light output, for example from Philips. 100% buy recommendation.
