ᐅ Is a central 12V DC power supply for LED light strips practical?

sub-xeroHello friends of light ;-)
I want to use LED light strips in most rooms of a new building. Instead of hiding small transformers everywhere, I wondered if it would be technically sensible to install one central transformer per floor and run a separate 12V wiring with a switch for each room. Advantages from my perspective:
- Less power loss due to a central transformer
- Easier to install and maintain
What do you think about this idea? Has anyone done this before?

No, this is neither practical nor effective.
Although you will have lower power loss from using only one transformer, you will then need significantly thicker cable cross-sections to compensate for the higher power loss caused by the necessarily longer cables. This results in unnecessary expenses and potentially other issues such as interference, since the cables can act as antennas.
This approach is simply not done, and that is why there are hardly any examples of it.
