The brightness can be adjusted in three levels (100% - 40% - 10%) via the wall switch (standard rocker wall switch), so you can always create the atmosphere you want.
Switching on: When first switched on, the light shines at 100% of its output. Second level: Switch the light off and back on within 2 seconds to reduce the brightness to 40%. Third level: Repeat the process to dim the light to 10% of its output.
For optimal use of the dimming function, switch the light off and on within an interval of less than 2 seconds to enter dimming mode.
Please note that the dimming function has no memory function. This means that after a complete switch-off (e.g. disconnection from the mains), the light does not save the last brightness level you set. When switched on again, the light always starts at 100% brightness.
The light must not be dimmed via an external dimmer or a smart home system, but only in three levels via a normal rocker wall switch.
