A statement light does not have to begin as one enormous object. Modular lighting builds visual presence by repeating a smaller unit—then changing the number, spacing, direction or height of those units to suit the architecture.
That idea is receiving a timely demonstration at London Design Festival 2026. The festival's official programme describes Lee Broom's forthcoming The Chant Chambers as an expansion of one lighting concept into oversized chandelier compositions, wall lights, linear pendants and continuous architectural structures. The installation is scheduled for September 15–20, 2026, during the wider festival.
This article is not a review of an installation that has not yet opened, and it does not recommend copying a specific designer fixture. Instead, it uses the verified programme announcement and the designer's explanation of repetition as a starting point for a practical residential question: how can repeated light modules create scale without making a room feel crowded?
What modular lighting means in a room
A modular fixture uses a repeatable component or visual unit within a larger composition. The module might be a glass block, globe, tube, shade, frame or illuminated bar. The final installation can grow horizontally, vertically or in layers while retaining one recognizable design language.
Modularity is different from simply hanging several unrelated pendants. A successful composition has rules: consistent geometry, intentional spacing, a readable alignment and a clear relationship to the room. The modules may vary, but the variation feels controlled.
Why this 2026 design event matters
The official London Design Festival description says the Chant concept is being extended from a singular design into a family of illuminated forms. It identifies large square formations, linear arrangements, wall-mounted versions and sections that can connect at right angles. Those details show three broader design directions worth watching:
- A product becomes a system. One visual language can address a dining table, wall, corridor and double-height void.
- Scale comes from aggregation. Repetition can create a substantial chandelier without relying on one oversized shade or crystal body.
- Light becomes architectural. A modular composition can follow an axis, turn a corner or define a zone rather than merely occupy its center.
In an interview accompanying the announcement, Broom describes simple geometry as a framework for exploring repetition, material and proportion. That is a designer's viewpoint, not a universal rule, but it gives homeowners and project teams a useful way to evaluate complex lighting: first identify the compositional rule, then decide whether it supports the room.
Four controls: scale, spacing, rhythm and hierarchy
| Design control | What it changes | What to verify |
|---|---|---|
| Scale | The perceived visual weight of the complete composition relative to the room and furniture | Overall width, height, depth, ceiling volume and important sightlines |
| Spacing | Whether individual modules read as separate lights, a continuous line or one luminous mass | Center-to-center distance, gaps, glare and shadows between units |
| Rhythm | How the eye moves through repeated elements | Regular, alternating or graduated sequence—and where that sequence begins and ends |
| Hierarchy | Which light is dominant and which layers support it | Relationship to wall lights, downlights, table lamps and architectural illumination |
These controls are related but not interchangeable. Adding more modules increases quantity, but it does not automatically improve scale. Reducing the gap may create a stronger visual mass while also increasing brightness and glare. A stepped arrangement can fit a staircase, yet feel restless over a rectangular dining table.
Choose the composition from the architecture
Over a dining table: use the furniture as the organizing line
A linear or compact rectangular composition usually belongs to the table, not the full room. Check the table length, fixture width, end clearances, hanging height and views between seated people. A modular pendant can be long without being visually heavy when the units are small and well spaced.
Start with our dining room lighting guide, then use the modular decision table in this article to refine the form.
In a double-height living room: design for volume and viewpoints
A tall void may need a composition with enough vertical depth to remain legible from the lower floor and an upper landing. But a larger object also creates more suspension points, cable coordination and maintenance work. Review the fixture from the entry, seating area, staircase and upper level—not just from a front elevation.
Our guides to chandeliers for high ceilings and chandelier drop length cover the dimensional questions that a festival photograph cannot answer.
Over a stair or in a foyer: let the sequence support movement
A cascading or staggered modular composition can follow vertical circulation, but the lowest unit still needs safe clearance and a logical relationship to landings. Avoid adding drops simply because the ceiling is tall. Each level should contribute to a readable whole.
Across an open-plan room: repeat a language, not necessarily one fixture
Using the same module over a dining table and in a living-room chandelier can connect two zones. The compositions should not compete at equal scale. Let one become the focal point and allow the other to be quieter, smaller or more linear.
A practical modular-lighting worksheet
- Draw the occupied zone. Mark the table, seating group, stair opening or circulation path the light must serve.
- Record the available envelope. Note maximum width, depth, drop, clearances and visible ceiling conditions.
- Choose one compositional rule. Grid, line, cascade, cluster or right-angle path are different starting points.
- Test three module counts. Compare a restrained, balanced and dense version rather than approving the first rendering.
- Check the unlit appearance. The frame, cables and glass remain part of the architecture during daylight.
- Separate visual effect from useful light. Confirm task illumination, glare and controls instead of assuming more modules solve every lighting need.
- Document the installation system. Record total weight, canopy or ceiling plate, suspension points, driver access, dimming and replacement parts.
- Review maintenance access. A dramatic void composition may require lift access or special cleaning procedures.
Module count is not a sizing formula
There is no universal equation that turns room area into the correct number of modules. Two modules can differ in output, material, transparency, size and visual weight. Ceiling height, surrounding finishes and daylight also affect perception.
Use numerical rules as early checks, not final proof. The existing chandelier sizing guide can establish an initial envelope. Then evaluate the complete modular composition with scaled drawings, reflected ceiling plans, elevations or mockups.
What designers and contractors should request
- overall assembled dimensions and total weight;
- module dimensions, quantities and spacing;
- ceiling fixing and suspension-point layout;
- canopy, remote driver and junction-box requirements;
- light output, distribution, color quality and dimming data;
- control grouping if modules operate separately;
- replacement-module availability and finish consistency;
- cleaning, relamping or driver-access method; and
- shipping sequence, on-site assembly and installation tolerances.
Place those fields in a residential lighting brief and preserve decisions in the project procurement record. Professional teams planning customized compositions can contact the LuminexHome Trade Program.
When modular lighting is—and is not—the right choice
It can work well when the architecture needs a specific length or depth, several zones should share one design language, a high ceiling requires visual volume, or the project benefits from phased and documented customization.
It may be the wrong choice when the ceiling cannot support the assembly, maintenance access is poor, the room already has several competing focal points, the supplier cannot document replacement modules, or the installation complexity exceeds the project's budget and schedule.
For a more atmospheric approach, our article on material, reflection and movement explains how a room can feel visually rich without filling every part of the ceiling.
LuminexHome takeaway
The useful lesson from modular lighting is not “more lights make a better statement.” It is that a simple element can become architectural when scale, spacing, rhythm and hierarchy follow a clear rule. Begin with the room, test the composition in context, and treat support, controls and serviceability as part of the design—not details to solve after purchase.
