The seven most common lighting design mistakes – and how to avoid them
Hardly any trade is considered as late and regretted as long as lighting. The good news: almost all lighting mistakes follow the same pattern – and can be avoided in the planning phase with little effort. Here are the seven we encounter most often.
1. The lonely outlet in the middle of the ceiling
The classic from the building shell: one ceiling outlet per room, dead center. With that, the most important decision has already been made – against good light. Rooms need light where things happen: above the table, on the wall, in the shelf. Whoever plans outlets and empty conduit early keeps every option open.
2. One layer of light for everything
General lighting alone makes rooms as flat as an office corridor. Good light is built in layers: ambient light, zone light, accent light – only their interplay creates atmosphere. As a rule of thumb: every living space deserves at least three layers of light, separately switchable and dimmable.
3. Color temperatures that don't match
2700 Kelvin in the living room, 4000 in the hallway, something cold white in the kitchen – and the home looks thrown together. Color temperatures should be defined like wall colors. And wherever light is meant to follow the day, plan Tunable White from the start – retrofitting it is expensive.
4. Glare ignored
The brightest luminaire is useless if it glares: downlights above the sofa, spots aimed toward the bed, reflective worktops. Good planning thinks from the perspective of use – sitting, lying down, at the stove – and chooses optics with appropriate shielding.
5. Dimming forgotten – or badly matched
Undimmed light is like music with only one volume. And where dimming happens, the technical trap lurks: luminaire, driver and dimming method have to match, or the light flickers. In our designs, dimming is the default – done properly via DALI, not with makeshift solutions.
6. Banks of switches instead of scenes
Six rockers next to the door, and nobody knows which one does what: the most visible symptom of missing lighting design. Whoever thinks in scenes – cooking, dinner, cinema, night – gets by with one elegant keypad and still controls more light than ever before.
7. Shading treated as an afterthought
Daylight is the best luminaire in the house – if you control it. Whoever plans exterior blinds and curtains separately from artificial light gives away both: glare protection at the workplace, passive cooling in summer, soft light in the evening. Light and shading belong in one hand and one logic.
The pattern behind all seven
Each of these mistakes arises when light is treated as a parts list instead of a concept. The order of good lighting design is always the same: first use and moods, then layers of light and control, and only then the luminaire. The most beautiful object comes last – and works twice as hard for it.
