Lighting·32 guides
Ceiling lights and home lighting
Lighting is judged on three quantities: luminous flux in lumens, colour temperature in kelvins and the colour rendering index. Knowing them is enough to read a spec sheet and compare two ceiling lights.
These guides answer lighting questions room by room, and the one that comes up most: what to do when the ceiling offers a single light point.

Changing a ceiling light yourself: the six steps, and the two mistakes to avoid
Cut power at the breaker, not at the switch. Check the mounting before ordering. The rest takes half an hour.

How many lumens do you really need per room?
Watts have meant nothing since LEDs arrived. The right benchmark is lumens per square metre, and it changes from living room to kitchen.

CRI: the number that explains why your colours change at night
Under low-CRI light, a wooden floor turns grey and a sofa loses its shade. What that number measures, and why almost nobody displays it.

Ceiling light for a modern living room: four families, one question to ask
Pendant, ceiling light, recessed spots, track. What decides is not style but available height and the number of electrical points.

The best LED ceiling light: how to recognise one without relying on reviews
Five values are enough to rank any model. The ones a good manufacturer displays, and the ones it hides when they are bad.

Wooden ceiling light: what separates real wood from a printed finish
Wood overhead warms a room like no other material. Three checks so you do not pay for plastic film at walnut prices.

Bedroom ceiling light: the central light is the one that bothers most
Above a bed, strong frontal light before sleep delays falling asleep. What to look at, and why dimming comes first.

How much does a ceiling light cost per year? The calculation in three lines
A 30 W LED ceiling light on five hours a day costs around €8 a year. What really weighs on the bill is elsewhere.

Kitchen ceiling light: why your worktop stays in shadow
The ceiling light is behind you when you chop, so your body casts the shadow. The answer is two levels of light, not a stronger one.

The luminaire that disappears: why the best ceilings are the ones nobody looks at
A striking ceiling light draws the eye upward, where there is nothing to see. The opposite school, and what it demands.

Hallway and entrance ceiling light: the one room where nothing else works
Passage, limited height, short and repeated switching. The three constraints that rule out everything but a flat profile.

Ceiling light for a large open-plan room: why one is never enough beyond 30 m²
Beyond 30 m², two luminaires beat one very large. The rule of zones, and how to avoid lobby lighting.

Dimmable LED ceiling light with remote: what to check before ordering
Not every model advertised as dimmable dims the same way. Three checks, and what you get under €200.

LED ceiling light flickering: the three causes, in order
Nine times out of ten it is the wall dimmer, not designed for LEDs. The other two causes are diagnosed in five minutes.

Black ceiling light: stunning in a photo, subject to two conditions in a real room
On a white ceiling, black becomes a permanent point of fixation. The two setups where it works, and the ones where it weighs.

Ceiling light or recessed spots: the calculation nobody does before the works
Spots need a hollow ceiling, six to ten points, and a permanent decision. A ceiling light swaps out in twenty minutes. What that really implies.

Ceiling light or pendant: what actually decides, and it is not taste
Ceiling height and what the room is for settle it before aesthetics. The height rules, and the special case of walk-through rooms.

Ceiling light for a small 10 m² room: the too-small trap
In 10 m², a tiny luminaire does not lighten the room, it shrinks it. The right diameter, and why warm light enlarges.

Ceiling light and low ceiling: the height you must not go under
Under 2.50 m, every centimetre counts. The clearances to respect, and the luminaires that become impossible.

A ceiling light that dazzles: where the discomfort comes from and how to end it
Glare comes from contrast and a visible source, not from output. Three causes, three remedies, two of them free.

Round white ceiling light: the best-selling shape, and what separates the models
They all look alike switched off. What tells them apart comes down to three figures that never appear in the photograph.

Lighting a dining table: the one room where a ceiling light is not the answer
Above a table you need light brought down and a defined circle. The exact dimensions, and the case of a table that sits elsewhere.

Living room ceiling light: the four figures to check before ordering
Diameter, lumens, kelvins, CRI. The living room is where a bad ceiling light shows most, and where it stays longest.

Does a ceiling light that is also a fan really exist?
Yes, and since retractable blades, without looking like a fan. How it works, what it costs, and the honest limits.

Lighting a conservatory: the room where artificial light comes second
Flooded with daylight, pitch dark at night, and overheated in summer. The three constraints of a conservatory and what they impose overhead.

How much to spend on a ceiling light? Count over ten years, not on the label
A luminaire stays up for ten to fifteen years. What costs you is not the purchase price, it is the integrated LED you cannot replace.

What ceiling light for a 25 m² living room? The exact figures
90 cm in diameter, 2,500 to 3,750 lumens, 2700K in the evening. The full calculation, and what it means in real models.

Replacing a ceiling light: the question nobody asks before buying
Changing a ceiling light means opening the only fixing point in the ceiling. What goes there decides your summer and your winter, not just your lighting.

Replacing a chandelier with a ceiling light: three surprises when you take it down
The weight, the mark on the ceiling and the drop in light. What you find when unhooking a chandelier, and how to anticipate it.

2700K, 4000K or 6000K: which light temperature for which room?
Colour temperature sets the mood more surely than wattage does. The room-by-room benchmark, and why a single value is never enough.

One room, one light point: how to manage without building work
Most homes offer a single feed at the ceiling. Three ways to get real light out of it, without drilling or running cable.

Living room lighting: the golden rules for perfect light at every hour
Three layers of light, colour temperatures, common mistakes: master living room lighting like an interior designer.
