  3. Phase-out of incandescent light bulbs - Wikipedia

    en.wikipedia.org/wiki/Phase-out_of_incandescent...

    The color temperature of incandescent bulbs – essentially the actual temperature of the hot filament – decreases as the voltage applied is reduced by a dimmer, and the light becomes visibly "warmer"; this does not happen with other technologies. However, Philips has designed LED bulbs that mimic this phenomenon when dimmed. [172]
