Kitchen Lighting: The Rules That Change Everything
Alborra
Successful kitchen lighting goes unnoticed: you can see, and that is all. Failure, on the other hand, shows in a second, in the shadow falling on the chopping board or the single ceiling light that flattens the whole room. Four rules settle almost every case, and none of them calls for major works.
How many lumens for kitchen lighting
The first rule comes with figures. Kitchen lighting needs about 300 lux on average across the room and 500 lux on the worktop, where you handle knives and judge a cooking job. To move from lux to the lumens printed on the packaging, multiply the area by the target level: a kitchen of 10 square metres therefore calls for roughly 3,000 lumens of general lighting, with the task lighting over the worktop on top. Allow generously for your kitchen lighting, because wall cabinets, matt tiles and a dark ceiling absorb a share of the light that no calculation accounts for. Conversely, very light kitchen lighting over gloss white cabinet doors will look brighter than the figure suggests. Hold on to the principle: you add sources, you do not overload a single point.
Three layers rather than one point: the real rule of kitchen lighting
A single central fitting cannot light a kitchen properly, because you work with your back to it. Good kitchen lighting is built in three superimposed layers. The general layer comes from the ceiling, a designer flush ceiling light or spread-out spotlights, and lets you move around without bumping into a unit. The functional layer, placed under the wall cabinets, is the one that removes the shadow cast by your torso: that is the subject of our guide to worktop lighting. The decorative layer of the kitchen lighting, finally, comes down over the island or the table as a pendant light, and it is what gives the room its character in the evening. Each switches on separately, and it is precisely this independence that makes the quality of kitchen lighting: in the morning you want everything, at 10 pm you want only the island. For the choice of the fittings themselves, our guide to kitchen light fittings goes through it zone by zone.
The mistakes that ruin kitchen lighting
There are four, and they come up every time. The first is kitchen lighting placed behind the user: spotlights lined up down the middle of the ceiling throw your shadow exactly onto the worktop, and no amount of power will correct that. The second is a jumble of colour temperatures, a worktop in neutral white at 4,000 kelvins and a pendant in warm white at 2,700, which gives the impression of two rooms badly stitched together. The third is the total absence of dimming: kitchen lighting that knows only on and off stays utilitarian, whereas a dimmer on the decorative layer alone is enough to make it liveable. The fourth, the most expensive to put right, is forgetting colour rendering: below a CRI of 80, food loses its sparkle and real travertine and solid walnut alike look washed out. Check this index before the power.
Switches and circuits: controlling your kitchen lighting
Well-planned kitchen lighting is controlled from at least two places: the entrance to the room and the worktop, so you never cross it in the dark. Each layer deserves its own circuit, and therefore its own switch, which is planned at the time of the refit and costs very little at that stage. If the walls are already finished, kitchen lighting can be completed without chasing: rechargeable or motion-sensor strip lights under the wall cabinets avoid running a new cable. Think, finally, about the height of the controls: a two-way switch at 1.10 metres is found by feel, whereas at 90 centimetres it disappears behind a base unit. And if you fit a dimmer on the kitchen lighting, check that the sources carry the word "dimmable", otherwise they will flicker or buzz, as our guide to the G9 bulb explains.
Conclusion
Three independent layers, 500 lux on the worktop, light that comes from in front of you and a CRI above 80: that is the essence of kitchen lighting that lasts. The rest is a matter of taste, not technique. For the visible part of the scheme, Alborra's pendant lights and flush ceiling lights state the diameter, the cap and the adjustable drop, the three dimensions that decide the final height.
