Good to know

The THE DIMAX 540 plus B is a flush-mounted device, meaning it fits into a standard wall box behind a pushbutton cover. It is compatible with a wide range of dimmable LED lamps, but for best results, use lamps that are explicitly marked as dimmable. The minimum brightness can be adjusted to prevent flickering or drop-out at low levels. Installation should be carried out by a qualified electrician in accordance with local regulations.
