Quel plafonnier éclaire le mieux ?

Celui dont le flux couvre la surface sans créer d'ombre dure. Comptez 100 lumens par m² pour un salon, 200 pour un plan de travail, et répartissez la lumière sur deux ou trois points. Un plafonnier encastrable éclaire large et uniforme ; il éclaire mal un détail précis.

Est-il possible de poser des spots sans faux plafond ?

Oui, à condition qu'il reste une réserve au-dessus du plafond fini. Un spot encastrable se loge dans un vide de 2 à 8 cm selon le modèle ; dans une dalle pleine, il faut noyer un boîtier. Sans réserve, mieux vaut assumer la saillie que forcer un encastrement.

Est-ce que les spots LED chauffent ?

Oui, mais bien moins qu'un halogène de flux équivalent. La chaleur part par l'arrière du module, d'où la nécessité de laisser de l'air. Coincé dans un coffrage isolé, un spot LED s'use plus vite et peut déclencher sa protection thermique.

Quels sont les différents types de spots encastrables ?

Trois familles : le fixe, l'orientable et l'extra plat. Le fixe éclaire droit vers le sol ; l'orientable se braque vers un mur ou un plan de travail ; l'extra plat se contente de 2 à 3 cm de réserve. La hauteur disponible tranche avant le style.

Comment installer des spots encastrables au plafond ?

Coupez le courant, repérez l'arrivée existante, tracez les axes au crayon, puis découpez à la scie cloche au diamètre exact du produit. Espacez les modules régulièrement et gardez 50 à 70 cm du mur pour éviter un mur trop éclairé. Le reste tient au calepinage.

Recessed ceiling light: choosing the right ceiling lighting

This article is also available in French: Plafonnier encastrable

06/10/2026 · 8 min read · By the Designix team

Check the clearance above the ceiling before buying anything: 2 to 3 cm for an ultra-slim module, up to 8 cm for a GU10 bulb spotlight. Also measure the space between the slab and the finished ceiling. That constraint decides what you can install, not the style.

Which ceiling light gives the best light?

The one whose output covers the surface without casting hard shadows. Allow 100 lumens per m² for a living room, 200 for a worktop, and spread the light across two or three points. A recessed ceiling light gives broad, even light; it lights a precise detail poorly.

Recessed, surface-mounted or pendant: which to choose?

The mounting changes the effect before it changes the budget. If you are revisiting a lighting plan for a living room and living space, start from the room plan and how it is used rather than from the product sheet.

Recessed: the source disappears, only 3 to 5 mm of trim sits flush
Surface-mounted: no cut-out, 3 to 10 cm of height lost
Pendant: the light comes down, best kept for tables and islands

What our catalogue survey shows

The Grand plafonnier collection has 378 references as of 6 October 2026. On a survey of 222 of those listings on the same date, 97% declare a surface mounting and 1% a recessed mounting: recessed remains a niche choice, often dictated by ceiling height.

The declared durability points the same way: on those 222 listings, 78% advertise a 5-year warranty and 100% mention CE marking. As for looks, many of these models read as a minimalist ceiling light, white or black, blending into the plaster.

Recessed, surface-mounted or pendant: what each mounting requires

	Recessed ceiling light	Surface-mounted ceiling light	Pendant
Effect on the ceiling	Flush, disappears	Visible and deliberate	Hangs down into the volume
Clearance needed above the ceiling	Yes, a free air gap	None	None
Nature of the light	Direct, often adjustable	Direct and diffuse	Diffuse, carried by the drop
Rooms where it is essential	Hallway, bathroom, kitchen	Living room, bedroom, entrance	Dining room, island, large volume
Protection rating to favour	IP44 in wet rooms	IP20 is enough in dry rooms	IP20 is enough, outside wet zones
Maintenance	A cloth on the trim	The whole bowl to clean	The shade, more often
Share in our survey of 222 ceiling lights (6 October 2026)	1%	97%	2%

Our selection of large-format ceiling lights brings both families together, dimensions included, so you can compare like for like.

Can you install spotlights without a false ceiling?

Yes, provided there is clearance above the finished ceiling. A recessed spotlight sits in a void of 2 to 8 cm depending on the model; in a solid slab, a housing has to be sunk in. Without clearance, it is better to accept surface mounting than to force a recess.

The three scenarios

Suspended plasterboard ceiling: 6 to 10 cm of void, recessing is straightforward
Slab with a service void: 3 cm is enough for an ultra-slim module
Solid slab: no chasing possible, either a sunk housing or switch to surface mounting

Beamed ceiling, ceiling that holds nothing: what alternatives?

Exposed beams break the alignment of spotlights and intercept the beam. Aim the light upwards, or choose a ceiling light for beamed ceilings, fixed between two joists.

When the ceiling can take nothing, light is built in layers: wall lights, floor lamps, reading lamps. Our guide to lighting a room without a ceiling light details this distribution.

Do LED spotlights get hot?

Yes, but far less than a halogen of equivalent output. The heat leaves through the back of the module, hence the need to leave air. Trapped in an insulated box, an LED spotlight wears out faster and may trigger its thermal protection.

Air clearance matters more than wattage

An LED module dissipates its losses through the rear heatsink. Allow 2 to 3 cm of free air around the housing and do not pack insulation against it. A module kept cool lives up to its promised lifespan.

IP20 or IP44: what the room demands

IP20: dry rooms, living room, bedroom, hallway, office
IP44: bathroom outside the shower zone, kitchen near the sink
To check: the same rating on the module and on its bulb

In a damp room, the module is often replaced without removing the housing: IP44 bulbs exist in common caps.

In which room should the light disappear into the ceiling?

What are the different types of recessed spotlights?

Three families: fixed, adjustable and ultra-slim. The fixed one lights straight down; the adjustable one can be aimed at a wall or a worktop; the ultra-slim one needs only 2 to 3 cm of clearance. Available height decides before style does.

Fixed, adjustable, ultra-slim

Type	What it lights	Clearance needed
Fixed	a regular cone, no adjustment	5 to 8 cm
Adjustable	a precise point, a wall, a worktop	5 to 8 cm
Ultra-slim	broad and diffuse, no relief	2 to 3 cm

On an ultra-slim model, the trim sits flush with the plaster. That detail is what makes the light disappear, and it is also the hardest to fix if the cut-out is too wide.

GU10 cap or integrated LED module?

GU10: interchangeable bulb, you change the colour without changing the spotlight
LED module: slimmer, but the source is sealed in the housing
E27 and G9: on large diameters, when you want to keep control

Several sources in the same ceiling complement each other well: recessed LED downlights light the circulation while a central fixture sets the mood.

Once the module is chosen, looks remain. Flat shapes and large curves dominate the season, to the point of inspiring the sleekest trending ceiling lights.

And if you prefer a single fixture to a line of spotlights, an LED ceiling light covers the same surface with far fewer cut-outs.

How do you install recessed spotlights in a ceiling?

Switch off the power, locate the existing supply, mark the axes in pencil, then cut with a hole saw at the exact diameter of the product. Space the modules evenly and keep 50 to 70 cm from the wall to avoid an over-lit wall. The rest comes down to layout.

Reusing the existing supply and drilling the right diameter

A central light point often feeds the whole line: spotlights tap off it, in parallel or in series depending on the wattage. The cut-out diameter is given to the millimetre on the product sheet, and that is the one to follow, not the trim diameter.

Our guide to the diameter of a recessed spotlight covers the usual matches between cut-out and ceiling result.

If you are replacing a central point with several sources, the tapping logic is the same as for changing a ceiling light.

In a living room, alignment matters as much as technique: installing recessed spotlights in a living room means starting from the sofa and the rug before marking anything.

How many spotlights, and at what distance from the wall?

The number is calculated in lumens, not in number of housings. Aim for the equivalent of 100 lumens per m² for general lighting, then spread that total. Our method for working out how many spotlights per m² gives the full calculation.

One module every 1 to 1.50 m on a standard 2.50 m ceiling
50 to 70 cm from the wall to avoid an over-lit wall
Two parallel lines in a wide room rather than a central alignment

Spacing tightens above a worktop and widens in a circulation area. The distance between ceiling spotlights is always read according to the mounting height.

Frequently asked questions about the recessed ceiling light

Can you install spotlights without a false ceiling?

Yes, provided there is free clearance in the slab or in the void above. Otherwise, an ultra-slim model that needs almost nothing, or a surface-mounted ceiling light, takes over without major work.

Which ceiling light gives the best light?

The one that suits the room. A recessed model gives direct, discreet light, while a surface-mounted model lights the whole surface. Spreading several sources beats a single source, however powerful.

Do LED spotlights get hot?

Less than a halogen of comparable wattage, but the module does heat up and dissipates through the back. Hence the importance of leaving free air behind the light rather than packing insulation against it.

Is a recessed spotlight cover mandatory?

It is not required everywhere, but it protects the insulation and nearby materials from the heat of the module. In an insulated ceiling, it is what stops the wool being pressed against the fixture.

How do you install recessed spotlights in a ceiling?

You mark the position, drill at the diameter stated by the manufacturer, connect to the existing supply and then clip the spotlight into its housing. Switch off the power at the breaker before any work.
