You do not. This is a common misconception. An authentic sunset simulation requires a specific far-red channel. The lamp must be able to extend the far-red glow longer than all other colors. In the SeriesX, however, the far-red is integrated into the bloom channel. Many other manufacturers already refer to a simple dimming function as sunset simulation. This means that the light is gradually dimmed instead of going out abruptly and directly. This function is also possible with our GC-SIGNAL. However, we do not want to explicitly call this a sunset simulation.
