Keep in mind that you need a native application to enable special modes, such as the permanent color change mode. The Dawn mode was also very useful, for 15 minutes the light bulb changes color temperature and brightness, simulating dawn, at the end the brightness is set to 100%. Helps to get up easier if administered 10 minutes before the alarm. Different pros: Excellent quality of materials; High brightness* (1 bulb per approx. 15m²); Working with Alice But here it is worth considering that there is nothing but a change in color and brightness. Has cons: For an ordinary room (15m²), you need at least 2 light bulbs for a bright glow. Of course, one is enough, but keep in mind that insufficient brightness strains your eyes, and you can always reduce excess brightness.
