Installing a chandelier on a DCL box: step by step

Switch off the circuit breaker, unscrew the cover of the DCL box, then connect the three conductors to the terminal block: earth, neutral and live. The box already carries the weight of the light fixture, and the chandelier is then fitted in a few minutes. Tighten each screw, tug gently on the wires, then restore the power.

How do you wire a chandelier to a DCL box?

Three conductors arrive in the box: earth, neutral and live. You identify them, slide them into the corresponding terminals on the chandelier, tighten, then tug gently on each wire to confirm the contact. The box is already screwed to the ceiling: no improvised connector block, no wire to pull out of the wall.

What the DCL box contains

• A terminal block with three positions, one per conductor, with colour coding.
• A base plate screwed onto the flush mounting box, which takes the load of the light fixture.
• A cover to unscrew, closed again once the chandelier is in place.
• A hook on some models, invaluable for hanging light fixtures.

Wiring, step by step

1. Switch off the circuit breaker and check that there is no current.
2. Unscrew the cover and identify the three conductors.
3. Connect each wire to the terminal with the same function on the chandelier.
4. Tighten, then pull gently on each conductor.
5. Clip everything back and restore the power.

Unsure about the colours? The method for wiring a ceiling light sets out the colour coding step by step, including the case of old wiring with no earth conductor.

The procedure is the same for a model with several light points: each socket runs from the same terminal block. Our guide to fitting a pendant light on a DCL box details this slightly denser assembly.

What is a DCL in electrical terms?

DCL stands for dispositif de connexion pour luminaire, a connection device for light fixtures. It is a plate fixed to the ceiling, in place of a socket or bare wires, which brings together the terminal block, the mechanical support and sometimes a hook. It allows any ceiling light fixture to be connected without altering the installation.

What a DCL box replaces

• The screw socket, which only supports the weight of a bulb.
• The improvised connector block, often poorly tightened and with no load support.
• The bare wires hanging down, to be stripped every time the light fixture is changed.
• The hook alone, which holds the light fixture but not the wiring.

New or old: what you find on site

In new builds, the light point is installed at the same time as the wiring and simply awaits its chandelier. In older properties, you still come across sockets, connector blocks or a wire coming out of the ceiling. Our guide to installing a light fixture on a DCL box describes these three situations and how to start cleanly from an existing point.

There is no obligation to redo an installation that works. However, a point with no mechanical support makes every intervention harder, and changing a chandelier then becomes a DIY job rather than a simple replacement.

How do you fix a chandelier to the ceiling without a hook?

The light fixture is then held on its mounting plate, or on a ceiling rose fitted in place of the hook. The mounting plate comes with the chandelier: it is screwed into the box and takes the mechanical load. The light fixture's instructions state the intended fixing method and the permitted load, and they are what decides.

Mounting plate and ceiling rose: what holds the light fixture

• The mounting plate, screwed directly into the holes in the box.
• The ceiling rose, a block fixed to the ceiling, for chandeliers hung on a chain.
• The steel cable, tensioned between the ceiling and the body of the light fixture.
• Suitable wall plugs for the ceiling material, solid concrete or hollow board.

Box present but without a hook

Some models include only a terminal block and two fixing holes. This is not a defect: many chandeliers are surface mounted and need no high-level anchoring point. For a heavy model or one hung on a chain, the fixing is supplemented with an added hook, as explained in our guide to fixing a chandelier to the ceiling with a hook.

If your box has no hook and you are still unsure which model to fit, describe your ceiling and the room to us: simply contact the workshop.

At what height should a chandelier hang?

The principle comes down to one sentence: the bottom of the light fixture must stay out of the line of sight of seated people, without overwhelming the room. Above a table, it is lowered until it creates a visual link with the tabletop. In a passageway, it is raised as high as possible.

Above a table

The right height is judged standing, then seated: the light fixture must not hide the faces of the people opposite. A wide chandelier is hung higher than a narrow model, otherwise it closes the room instead of opening it up.

A rectangular tabletop calls for an elongated model, a round tabletop for a circular or spherical shape. Our selection of dining room chandeliers brings together both families, with the matching cable lengths.

Before drilling, mark the centre of the tabletop on the floor and then transfer it to the ceiling. This marking out, described in our guide to hanging a chandelier, prevents the light fixture from being offset by a few centimetres.

In a passageway or corridor

Nobody sits there: the light fixture simply has to let a standing adult pass. A short model works better than a chain chandelier, and the choice is based on the volume to be lit rather than on a number.

Which chandelier should you choose for a DCL box?

Almost anything, on one condition: that the light fixture connects to the ceiling and that its weight stays within what the box accepts. In a survey of 66 chandelier references in our catalogue as of 1 October 2026, 94% are hanging models and 100% are rated IP20, so for indoor use only.

Caps and bulbs

In the same survey of 66 references as of 1 October 2026, 56% have an E27 cap, 14% an E14 and 12% a G9. E27 remains the easiest to live with: the bulb is available everywhere and can be replaced without tools.

Our collection of E27 bulbs covers warm white to cool white, enough to adjust the mood of a room without touching the light fixture.

Materials, styles and warranties

Again in this survey of 66 references as of 1 October 2026, steel features on 55% of models and glass on 24%. Warranties are split between 2 years for 53% and 5 years for 47%: a criterion to check before comparing two similar-looking models. Glass pendants are among the most viewed pieces; their transparency lets light through without weighing down a low ceiling.

Style is chosen after the room. Product pages state the recommended room, the cap, the material and the warranty, which avoids ordering blind. The Affordable Chandelier collection has 2,411 references as of 1 October 2026, more than enough to find the right size without settling for a generic model.

To filter, start from the use rather than the style: our lighting range is organised by room, which avoids comparing a hallway ceiling light with a living room chandelier. Reviews left by our customers can be found on our Google listing.

A well-chosen pendant light brings light down where it is needed instead of spreading it across the ceiling. That is often what makes the difference between a lit room and a finished room.

There remains the check that saves you from coming back down the ladder: power off, wires tugged one by one, screws tightened, light fixture stable. This check comes down to five points.
