Summary
Knowing how to choose light fixtures for an interior requires aligning precise technical parameters from the design stage. Specifically, an 800 lumen source does not offer the same rendering depending on the perceived power and ceiling height. It is the geometry of the room, not aesthetics, that dictates this initial calibration of the lighting.
How to choose your light fixture room by room
A 35 cm ceiling light centered in an 18 m² space inevitably leaves the corners in shadow. The physical dimensions of your space determine the type of light fixture long before any discussion about finishes. This respect for proportions ensures lasting visual comfort, whether for a work or resting area.
Pendant, ceiling, or wall light according to the room
To choose your light fixture rigorously, the ceiling-to-floor measurement determines the decision. Below 2.50 m, a flush ceiling light clears the visual circulation path. Above that, a pendant light lowers the light flux and enhances verticality. To refine these settings in a living room, our guide choosing living room lighting details our implementation methods.
The diameter of a light fixture is always calculated based on the floor area. In a rectangular configuration, I prefer two distinct sources to distribute a homogeneous diffuse light.
- Less than 10 m²: a diameter of 30 to 40 cm is enough to light the center without overwhelming the space.
- 10 to 15 m²: a span of 40 to 45 cm, complemented by a wall light to open up peripheral shadows.
- 15 to 20 m²: diameters reaching 50 cm, or the alignment of two symmetrical pendant lights.
- More than 20 m²: an imposing 60 cm chandelier, supported by secondary sources on the walls.
In an entrance or hallway, the height constraint is strict: the bottom of the lampshade must remain 2.10 m from the floor. To circumvent a ceiling that is too low, a wall lamp placed at 1.70 m is the most suitable technical solution.
What lighting for the living room, bedroom, and bathroom
Understanding how to choose a pendant light for the living room involves stratifying the sources. The method consists of combining a main source, a directional floor lamp, and ambient lighting on the periphery. This superposition creates clear contrasts while structuring the space.
In a bedroom, the bedside lamp adjusts to shoulder height for reading without glare. In the bathroom, IP44 spotlights on the ceiling coupled with frontal lighting eliminate shadows on the face. This primacy of function over pure design also applies to technical areas, as illustrated in our designer kitchen lighting article.
Designer lamps and pendants for the kitchen and dining room
Functional lighting in the kitchen requires 500 lux at the preparation surface. Strips fixed under the high storage units eliminate the projection of your own shadow on the work surface. On a central island, the pendant light is positioned 75 cm from the countertop to ensure optimal visual comfort.
In the dining room, the size of the light fixture should not exceed the width of the table. A table lamp on a low cabinet will then soften the ambiance in the late evening. At Olibam, our selection of Scandinavian designer light fixtures allows you to customize each finish to precisely meet the requirements of your project.
Choosing the right color and light intensity for your lighting
A pendant light set at 2,700 K in a living room creates a relaxing ambient light; at 4,000 K in the same space, it makes any relaxation impossible. The light's hue, measured in kelvins, defines the atmosphere as much as the function of your lighting. In reality, this is the most frequently neglected setting in an interior, although it directly influences your daily visual comfort.
Color temperature and light ambiance by room
To know which light color to choose, the Kelvin value is your only reliable technical reference. I recommend a warm white around 2,700 K for the bedroom, to naturally support nightly rest. Conversely, a neutral white of 4,000 K is essential in the kitchen, with a Color Rendering Index greater than 90 to accurately reproduce the correct hue of food and surfaces.
- 2,700–3,000 K (warm white): in the living room, bedroom, or dining room, this setting creates a space conducive to relaxation and dining.
- 3,500–4,000 K (neutral white): in the kitchen or for work, this value ensures precise and unambiguous visibility.
- 5,000 K (cool white): in a bathroom for makeup, this very technical rendering is reserved only for functional areas.
- Mix of temperatures: a warm light source combined with a targeted neutral point concretely structures the space, without generating glare.
In practice, maintaining a consistent color temperature in the same room visually unifies the volumes. The crossing of temperatures should only be considered to emphasize a specific use, never arbitrarily. What matters here is to remember that a CRI below 80 irrevocably dulls your decor.
| Room | Recommended temperature | Minimum CRI | Main use |
| Living Room | 2,700–3,000 K | 80 | Relaxation, ambiance |
| Kitchen | 4,000 K | 90 | Cooking tasks, worktop |
| Bedroom | 2,700–3,000 K | 80 | Rest, reading in bed |
| Dining Room | 3,000 K | 80 | Meals, conviviality |
| Bathroom | 5,000 K | 90 | Makeup, shaving |
| Office / Workshop | 4,000–5,000 K | 90 | Concentration, precision |
Lumens, base, and LED bulb for your designer light fixture
To understand how to choose a designer light fixture without sacrificing utility, the choice of a bulb is evaluated in lumens, not watts. It is the light intensity that defines the true perceived brightness in your room. Electrical power no longer indicates the quantity of light emitted by the light fixture. For a work surface, the position we maintain requires aiming for a precise illumination of 500 lux.
Specifically, the E27 format equips a large classic lamp, while the E14 fits into a smaller wall light. Before defining which light fixture to choose, checking this mechanical constraint ensures the fluidity of installation. To choose the right bulb, an A-rated model reduces consumption without altering the design. Find official resources for choosing LED lighting according to ADEME criteria.
Dimmers, dimmability, and smart lighting
Dimmable modules allow you to adjust your lighting according to the time of day, without requiring equipment changes. The difference lies in the strict compatibility between the bulb and the wall dimmer: incompatibility generates uncomfortable flickering. At Olibam, we systematically validate this pairing to ensure perfectly stable dimming over time.
A connected system simultaneously adjusts the light flux and heat emission from a digital interface. In a confined space, a variable floor lamp cleverly replaces several fixed points, provided it is oriented towards a light-colored wall. In my opinion, the goal remains to control the diffusion before it becomes dazzling to the eye.
Matching the design, materials, and style of your light fixtures to your decor
Between two models at the same price, it's often the finish, not the shape, that determines whether a wall light fits in or clashes. Specifically, the material of the light fixture communicates with your faucets and furniture handles. It is this precise detail that structures an interior.
Materials and finishes to harmonize your light fixture with your decor
To understand how to match your light fixtures to your decoration, I recommend aligning the finishes with existing hardware. A golden brass pendant light naturally complements your kitchen handles. In fact, a matte black on a lamp immediately links the light fixture to the surrounding dark woodwork.
- Glossy black glass: I reserve it for high volumes, for precise and directional lighting.
- Golden brass: this finish warms neutral palettes and pairs well with a minimalist design.
- Brushed aluminum: a sober and functional option, which captures ambient light without glare.
Fabric lampshades produce a diffuse light particularly suitable for softening the atmosphere of a bedroom. Frosted glass redistributes the light flux uniformly, eliminating harsh shadows. Conversely, metallic reflectors concentrate the beam downwards: to be preferred when functional lighting becomes the priority.
How to match pendant, wall, and table lamps in the same room
Designer light fixtures with simple geometries tolerate mixed uses better. This sobriety facilitates the integration of a wall light or a table lamp near a strong zenithal source. In practice, this choice avoids stylistic dissonance when combining an imposing chandelier with secondary sources.
- Visual hierarchy: I advise placing a single strong piece, then surrounding it with more discreet light sources.
- Correct proportions: above the table, the pendant light should not exceed the width of the tabletop.
- Overall coherence: connecting the main source to the floor lamp with a common aesthetic stabilizes the room's volume.
- Metallic accents: coordinating chrome or gold details calms the eye and structures open spaces.
Geometries like our Sven or FUGL models adapt easily, from a narrow entrance to a nighttime hallway. For reception areas, the Brann or IDA suspended models modulate the dining room's volumes. The flexibility of finishes allows these pieces to serve their purpose without being obtrusive.
The difference lies precisely in the finish: this is where our approach at Olibam makes perfect sense. We validate every dimension and every thermal setting with you before manufacturing begins. This method secures your choice and guarantees careful monitoring, with shipping within 3 to 5 weeks.

Frequently asked questions
How many lumens should you plan for a well-lit 20 m² living room?
A 20 m² living room needs approximately 8,000 lumens, but concentrating all this power on the ceiling flattens the room's volume. In practice, I recommend distributing this light source: a pendant light in the center, complemented by a wall light or a floor lamp in the corners. As in an entrance, dividing to better light ensures visual comfort without leaving shadowy areas.
What color temperature should you choose for a kitchen open to the living room?
A worktop lit at 4,000 K facilitates cutting, while the adjoining living room calls for 2,700 K to promote relaxation. In such an open kitchen, the light fixture must precisely materialize this invisible boundary. Specifically, reserve the cool lighting for the technical area and position a warm-toned pendant light above the central island.
