Ambient layers
The outer ring of the stack — soft room fill for Basel evenings and deep Altbau plans.
Layer stack
Why ambient comes first
Ambient light lets you move through a flat without hunting for switches. In Basel apartments with long corridors and rooms set back from the street, a single pendant rarely reaches the far wall. We build fill from walls and ceilings first, then add task and accent.
Plans mark which circuits belong to ambient so dimming does not kill the kitchen when you only wanted a softer living room.
Kelvin guide for room fill
Colour temperature choices keep plaster readable without turning winter evenings harsh. Typical bands we discuss on site:
| Kelvin | Use | Mood |
|---|---|---|
| 2700–3000 K | Evening ambient in living rooms and halls | Warm, settled after dusk |
| 3000–3500 K | Day-evening bridge in mixed Altbau rooms | Neutral fill without clinical white |
| 3500–4000 K | Higher ambient where courtyards stay dim | Clearer walls, still soft if diffused |
Rhein glare and winter dusk
Flats facing the Rhein can feel bright at noon and hollow at dusk when water reflection disappears. Ambient layers bridge that drop with low-glare uplights and wall washes that sit quietly beside sheer curtains.
Kleinbasel courtyard rooms
Courtyard rooms receive less sky. Ambient levels need to rise earlier in the afternoon, yet stay gentle for television and talk. Diffused sources and bounce from pale walls beat clusters of spotlights. On low ceilings we favour shallow fittings that keep headroom clear.
Materials and mounting
Timber floors and historic plaster need careful fixings. We note which walls can take weight and which need freestanding ambient lamps when landlords limit drilling. Schedules list lumen ranges so Basel suppliers order the right gear the first time.
Linking ambient to scenes
Ambient groups usually form the evening-base scene that stays on while task lights come and go. That habit keeps Swiss winter nights comfortable without every lamp at full output.
