An LED that really dims

Works as advertised in that it really does start out as bright 2700 degree Kelvin white light then dims to a warmer color. In a dining room where candle-light and LEDs might mix, this is a real solution. 40watt LEDs from many other companies do not dim well at all, but make a depressing, icy, shadowy "white" that's really unacceptable. (Only a very few, very special LEDs dim like incandescents and they have double light sources, namely a 2700 K LED combined with a 2400 K one. This Philips product has one set of 2700 K LED "filaments" that must serve both cases from white light to warm). It cannot match an incandescent bulb in dimming, but it comes close enough. Apparently LEDs need direct current. So, in the base of each bulb Philips packs in a tiny AC to DC power supply complete with a dab of (what?) to allow the heat the miniature semi-conductors make to transfer quickly to the metal light socket. No wonder such a bulb costs $5 or so apiece. Lire l'avis complet...
