Image box

A box with luminous images of different brightness levels.

Button control

• If the light is in Sleep Timer mode, pressing the button exits this mode and switches to Night mode, restoring the previous brightness.
• If the light is not in Sleep Timer mode, pressing the button:
  • In Day mode, it switches to Night mode, and vice versa.
  • In Night mode, it switches to Day mode, and vice versa.
  • In brightness and color temperature control modes, it toggles between available settings.
• Double-clicking the button toggles between Day and Night modes.
• Triple-clicking the button reduces brightness or color temperature.
• Quadruple-clicking the button sets the light to Sleep Timer mode and saves the current brightness.
• Holding the button causes changes in brightness or color temperature depending on the mode.
