Lighting design: My personal experience is that electricians believe they can do this on the side by themselves, and that is absolutely not the case. This plan practically screams at me, I am from the electrician.
There are a few basic rules:
- As you get older, you need more brightness. How much more, the lighting designer must know and do correctly.
- Illuminate corners, humans perceive what is bright, the rest of the room is basically dismissed by the brain. There are studies with a dining table in a room and guests sitting there. They recorded movement patterns. If the corners were illuminated, e.g. with a floor lamp or an up/downlight, they were entered and used. With a light strip above the dining table, people basically stayed in the cone of light.
- Situation-related lighting; if more than one situation, then more than one lighting.
- Decentralized, adapted to living habits. Were these queried?
- Glare-free.
By considering these, a lot of electricity and fixtures can be saved, by the way. I saw examples where the lighting costs were halved without users missing any brightness.
Although I have taken professional training courses in lighting design, in the end we commissioned a lighting company. That was worthwhile! Naturally, the half offended electrician believed we could have easily gotten that from him as well. In the past, there was a central light bulb in the middle; now the electrician practically makes the modernized form of that, nicely symmetrical pulled strips. That does not count as lighting design!
