absolutely precious ...

In quality and finish, this panel does not need to hide behind the well-known manufacturers.
A classy brushed stainless steel surface covers the board, in the middle of an LED film, as is used in laptop computers for display lighting, the translucent surfaces of the panels is a highlight in a looking-bluish, very bright light.
The entrance area benefits from this, as you. At night, only the illumination is active (built twilight switch), both the key on the Bund, and the keyhole is readily light
There is not necessarily a must, but a small switch box behind the panel facilitates the installation when the cable is greater than a 2 x 2, which is sufficient in theory for the installation.
The wiring for the different connection possibilities is doorbell detail in all variants.
