Warm dimming LED downlights, or dim-to-warm LED downlights, warm glow dimming LED downlights, are dimmable LED luminaires capable of replicating the color shift behavior of incandescent lamps as they are dimmed to a lower intensity. It is well-known that thermal radiators glows white hot when they are heated at full rated power. At full brightness the light produced by incandescent lamps has a color temperature falling within the range of 2700 K to 3300 K. However, when incandescent lamps are dimmed to produce a lower light output, the color temperature changes to as low as 1700 K. To the human eye, the light produced by incandescent lamps over the course of dimming appears to go from the neutral shade of white to orange-ish which is approximately the color of a match flame or light from the setting sun.
