LEDs equivalent to 25-watt incandecents? Yes!
LED bulbs do not usually come in a form equivalent to an incandescent 25 watt bulb (they are always 40 watts or 60 watts). So these are special. And special too because they dim to a warm low light, not gray whiteness! Are these a good value! Yes. Remember LEDs have to have direct current. Philips has to build a power supply into the base of each bulb ready to reduce 120 VAC from the wall plug to low volts DC for the LEDs. And the miniature circuity, moreover, needs a dollop of goo to transmit heat efficiently from the semi conductors to the bulb's metal socket. Really, I don't know how manufacturers can do it for just $4 per bulb.

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.
