Open-Plan Kitchen–Living Room Lighting: Zones, Scenes and Numbers
7 min reading time
One chandelier cannot light an open-plan space. Split it into zones — worktop 400-500 lux, island pendants at 70-80 cm (28-31 in), dining 200-300 lux, sofa 100-150 — tie them with warm 2700-3000 K and wire separate dimmed circuits for scenes.
In short: an open-plan kitchen–living room cannot be lit with a single chandelier — it is several scenes of life in one space. Split the light into zones (worktop 400-500 lux, the island, the dining table 200-300 lux, the sofa area), tie them together with one warm colour temperature of 2700-3000 K, and wire them as separate dimmed circuits so you can cook under bright light and dine under a soft one. In tropical villas and condos, where the kitchen often opens onto a terrace or pool, this zoning is what keeps the evening atmosphere intact. Here is the zoning, the layers, the pendant heights and the scenes — with numbers.
Not one chandelier but zones: worktop, island, table, sofa
One warm temperature 2700-3000 K ties the space together
Separate dimmed circuits: cook bright, dine soft
The main principle: one space, several scenes
An open-plan space combines three different scenarios — cooking, eating and relaxing. Each needs its own brightness and mood, yet everything must read as one space.
Why one chandelier is not enough
A central chandelier gives flat, even light — and kills the atmosphere: the sofa zone is overlit while the worktop sits in the shadow of your own hands. An open-plan room is lit in layers and zones, each for its own task.
Cooking needs bright functional light on the counter
Dining needs a warm intimate accent over the table
Relaxing needs soft diffused light, floor and table lamps
Transitions between zones should never be abrupt
What ties the space into one
Three moves that make different zones read as one interior rather than a set of rooms:
One colour temperature — 2700-3000 K everywhere
One CRI (90+) — colours stay honest across all zones
A repeating fixture material (brass, glass, rattan) as the visual thread
A shared ambient layer of light on top of the accents
Mismatched temperatures are the number-one mistake: a cold kitchen next to a warm living area looks like two different homes.
Zone by zone: numbers and heights
Four zones, each with its own target level and its own technique.
The kitchen work zone
Here you need bright, functional light directly on the counter — 400-500 lux. The golden rule: light must reach the surface from in front, not from behind your back, or you will work in your own shadow. The best solution is under-cabinet lighting plus downlights or a track above the work line.
Worktop illumination — 400-500 lux
Under-cabinet strips — light from the front, no hand shadows
Downlights or track above the work line
CRI 90+ — to see the true colour of food
The island and bar zone
The island is the visual centre of an open-plan space, so its light is both functional and decorative. Hang a row of pendants 70-80 cm (28-31 in) above the countertop: they light the surface and act as the jewellery of the room. For serious prep on the island, add concealed functional light as well.
Pendants over the island — 70-80 cm (28-31 in) above the counter
2-3 pendants or one linear fixture for a 2-2.5 m (6.5-8 ft) island
Decorative and task light in one
Its own dimmed circuit
The dining table
Over the table — a warm, intimate accent of 200-300 lux that gathers the family. Hang the pendant or chandelier 70-90 cm (28-35 in) above the tabletop, with a diameter roughly one third narrower than the table. This light always sits on its own dimmer: dinner calls for a glow, not a bright ceiling.
Table illumination — 200-300 lux, warm accent
Pendant at 70-90 cm (28-35 in) above the tabletop
Fixture diameter ≈ 1/3 of the table width
Always a separate circuit and dimmer
The sofa zone
Here the light is soft and diffused — 100-150 lux of ambient plus 300-500 lux of local reading light. Floor lamps, wall lights, table lamps and concealed cove lighting do the work. This is the zone that switches the whole space into evening mode, when the bright kitchen light is off and the terrace doors are open.
Ambient light in the lounge zone — 100-150 lux, soft
Evening scene: kitchen dimmed, the sofa zone lives
Scenes, circuits and typical mistakes
Scenes on dimmers
Split the space into lighting circuits, then combine them into one-touch scenes:
"Cooking" — bright work zone and island, living area dimmed
"Dinner" — warm accent over the table, kitchen almost off
"Guests / evening" — decorative and concealed light, minimal background
"Clean-up" — full bright light in every zone
"TV / relax" — only the sofa zone and cove lighting
The minimum is 3-4 separate dimmed circuits; the maximum is full scene control through a smart-home system or DALI.
Five open-plan lighting mistakes
One chandelier for everything — no zones, no atmosphere
Different temperatures in kitchen and living area — the space tears in two
Light from behind at the worktop — you cook in your own shadow
Everything on one switch — you cannot dim just the living area
No concealed or decorative layer — the interior falls flat at night
For a complex layout, a proper lighting design pays for itself: circuits and levels are resolved before the electrical first fix, not after the finishes.
FAQ
How do you light an open-plan kitchen–living room properly? Split it into zones and light each for its task: worktop 400-500 lux, island with pendants, dining table 200-300 lux as a warm accent, sofa zone 100-150 lux of soft light plus local reading light. Tie it all with one warm 2700-3000 K temperature and wire separate dimmed circuits.
Can one chandelier light an open-plan space? No — a single chandelier gives flat light and kills the atmosphere: the sofa is overlit and the worktop is in shadow. Open-plan spaces are lit in layers and zones: functional light in the kitchen, decorative over the table and island, soft diffused light in the lounge.
What colour temperature should an open-plan space use? One warm temperature, 2700-3000 K, in every zone. Mixing a cold kitchen with a warm living area visually rips the space into two rooms. One temperature and CRI 90+ bind it into a single interior.
How high should pendants hang over the island and the table? Over a kitchen island — 70-80 cm (28-31 in) above the counter; over the dining table — 70-90 cm (28-35 in). The light lands on the surface without glaring in your eyes or blocking the view of the person opposite. The fixture over the table should be about a third of the table's width.
How many lighting circuits does an open-plan space need? At least 3-4 separate dimmed circuits: kitchen work zone, island, dining table, sofa zone (plus concealed lighting). That is what makes "cooking", "dinner" and "relax" scenes possible — only the zones you need, at the brightness you need.
Do I need a lighting design for an open-plan space? For a complex layout — yes: the design resolves circuits, calculates levels and places outlets before the first-fix electrical stage. Redoing wiring after finishes is expensive. RODESIGNE prepares such lighting schemes and manufactures the fixtures to match.
