Modular Pendant Lighting: The Dune System

Modular pendant lighting solves a problem that fixed luminaires cannot: it lets a single lighting language scale from an intimate dining table to a six-metre hospitality volume without changing product. The Dune collection from MOSS Objects, co-designed by Daniel Becker and Elisa Bakaniev and awarded the iF Design Award 2025, is built entirely on this principle. Rather than a catalogue of finished sizes, Dune is a system of individually formed aluminium shades that link into configurable compositions. For interior architects and specifiers, that distinction changes how the fixture is chosen, drawn, and integrated into a space.

Modular Pendant Lighting as a Specification Tool

The phrase modular pendant lighting describes a fixture assembled from repeated units rather than produced as a single closed object. In the Dune collection, each unit is a hand-formed aluminium shade, and the composition is built by connecting these shades in chains. The number in each model name, from Dune 4 to Dune 20, states how many shades the composition contains. Because the system is additive, the same design vocabulary covers a small residential pendant and a large architectural installation, with no break in material or detailing between them.

This matters at the specification stage. A conventional pendant forces a choice between fixed sizes, and a space that falls between them ends up either over-lit or under-scaled. A modular system lets the specifier match the exact module count and configuration to the volume, the activity plane, and the sightlines. The fixture is sized to the room rather than the room being adapted to the fixture. It also means one finish and silhouette can run across a whole project, from the restaurant to the lobby to the private suites, while each space receives a composition scaled to its own proportions.

The Dune collection is the most technically involved product MOSS Objects makes, and that complexity is the point. The flexibility that makes Dune useful to architects is the same flexibility that asks for early, deliberate specification rather than a last-minute fixture selection. Treated as a system from the start of design development, it rewards the planning; treated as an off-the-shelf pendant, it loses most of its advantage.

Five Configurations, One System

Beyond module count, Dune offers five spatial configurations, and each produces a distinct relationship between the fixture and the room. Curve arranges the shades along a sweeping horizontal arc, well suited to dining tables, bar counters, and long reception desks where the light should follow a line. Cluster groups the shades into a dense, organic mass that reads as a single sculptural focal point, closer in spirit to a chandelier. Spiral winds the modules into a three-dimensional helix that shifts as the viewer moves around it, giving the composition presence from every angle.

The two vertical configurations address height rather than spread. Vertical Line stacks the shades in a descending column, designed for double-height atriums, stairwells, and entrance halls where the fixture should occupy the vertical axis without a wide horizontal footprint. Vertical Cluster concentrates that same vertical mass into a denser grouping for a more dramatic effect. Crucially, the same number of shades produces entirely different spatial results depending on the configuration: a Dune 20 reads as a generous horizontal feature in Curve and as a compact vertical helix in Spiral. The architecture of the space determines which configuration is correct, not the module count alone.

Each configuration also casts its own pattern of light and shadow. Because the aluminium shades are closed on top, the light falls in overlapping modular cones below while the bodies cast quiet geometric shadows above. A horizontal Curve spreads those pools across a surface; a Spiral layers them at different heights. For a designer, this means the configuration is a lighting decision as much as a formal one, and it is worth drawing in section before it is committed.

In practice, the configuration tends to follow the geometry of the space. Long, low rooms and tables take a Curve. A square volume that needs a single anchor takes a Cluster. Tall, narrow volumes such as stairwells and reception cores take Vertical Line or Vertical Cluster. Spiral is the choice when the fixture will be seen in the round, in the centre of a room rather than against a wall. Starting from the geometry of the volume, rather than from a preferred shape, usually points to the right configuration quickly, and it keeps the conversation with the client focused on the space instead of the catalogue.

Seven Sizes, from Dune 4 to Dune 20

Dune is produced in seven sizes: 4, 6, 8, 10, 12, 16, and 20 modules. At the small end, Dune 4 creates an intimate focal point for a side table, a banquette, or a compact residential dining setting. Through the middle of the range, Dune 8 and Dune 10 suit standard dining tables and reception zones. At the upper end, Dune 16 and Dune 20 reach architectural scale, spanning several metres in a Curve configuration or descending through a full double-height volume in a vertical arrangement.

Because each shade is individually formed rather than machined from a single block, no two shades in a composition are precisely identical. At scale, this produces a subtle variation across the piece that resists the mechanical uniformity often associated with modular products. Only the connectors between shades are CNC-machined; the shades themselves are shaped from aluminium sheet by hand in Berlin. The result is a system that behaves predictably from a planning perspective while keeping the irregularity of a handmade object.

Scale carries planning consequences. Larger compositions distribute mass across more connection points, and the total drop and span have to be coordinated with the ceiling structure and the activity plane below. As a rule, the lowest point of the fixture sits roughly 700 to 900mm above a dining surface and at least 2200mm above circulation routes. Drawing the chosen size against both the ceiling and the surface it serves is the most reliable way to confirm proportion before an order is placed.

Finishes, Material, and Light Quality

Dune is offered in five standard finishes: Silver Anodised, Silver Polished, Gold Tone, Copper Tone, and Dark Bronze Tone. Silver Anodised is the only anodised variant in the range, and Silver Polished is mechanically polished, uncoated aluminium. The Gold, Copper, and Dark Bronze tones are wet-lacquered over aluminium rather than anodised, which gives them their warmer surface character. Custom finishes are available on request for projects that need a specific match.

Finish choice is not only aesthetic. Silver finishes tend to recede in bright, daylit interiors, while the metallic tones gain presence and warmth under evening light, which makes them a natural fit for rooms with dark stone, timber joinery, or low-key lighting. The finish also affects how sharply the shadow pattern reads, so it is worth deciding alongside the configuration rather than as a final cosmetic step.

The structural and optical materials are consistent across the range. Each shade is formed aluminium, the diffuser on the underside of every module is PE, and the canopy is steel. Light comes from LEDs at a fixed colour temperature of 2700K with a colour rendering index above 90, warm white light that suits both residential and hospitality contexts. The closed aluminium body shapes that light into overlapping cones, warmer than a fully directional pendant but more contained than an omnidirectional source, while the PE diffuser softens the distribution below each shade.

Specifying the Dune Collection

Specifying Dune begins earlier in the design process than a standard fixture. Module count, configuration, finish, and total drop should be resolved during design development, with time allowed for material samples and technical drawings. The two largest sizes, Dune 16 and Dune 20, are wired as two separate LED chains so that each chain stays within safe extra-low-voltage limits, which means two driver positions need to be planned in the ceiling void. All Dune luminaires are dimmable; Triac drivers are supplied as standard, with DALI or 0-10V available depending on the market and the building management system.

Cabling and canopy detailing also belong in the early coordination. Dune uses standard cable and a steel canopy, and the driver for each chain sits within the canopy, so the electrical layout and the ceiling fixings should be confirmed with the structural and electrical teams before the ceiling is closed. Lead time for a configured Dune typically runs 10 to 14 weeks from order confirmation, reflecting the hand assembly involved, and finish samples on small aluminium plates can be supplied beforehand to confirm colour and surface under the project's own lighting.

Most projects are well served by the standard sizes and configurations, but the modular logic also makes bespoke variants straightforward. A custom drop length, a non-standard cable run for a tall atrium, or a specific finish match can be accommodated without redesigning the product, because the underlying module stays the same. In those cases the longer end of the lead time applies, and an early sample approval is worth building into the programme. The practical result is that one product family can carry a project from the most constrained residential corner to its largest public volume, with a single point of contact for drawings, samples, and delivery.

For architects and interior designers, the value of a modular pendant lighting system is the ability to treat light as a primary spatial element, scaled and configured to the volume rather than chosen from a fixed range.
