Sebastian Bergne is a London-based industrial designer known for clear, playful objects that balance engineering, craft and human interaction. For Curl he set out to rethink the archetypal table lamp: not just a light source with a shade, but a single gesture that joins lamp and reflector into one flexible, sculptural object.
What Curl is — product snapshot
Curl is a compact, sculptural LED table lamp with an articulated, curl-like reflector that joins the light source and reflector in a single elegant form. The lamp is dimmable and features a central dimmer switch; it also includes a tuneable LED module that lets the user adjust the white light temperature across a warm-to-cool range. Curl was developed for Luceplan and is presented as a well-resolved product that reads equally as lighting and as small sculpture.

Why the idea matters — simplicity as interaction
The core design move of Curl is an economy of gestures: combining reflector and body into a single element reduces visual clutter and invites playful repositioning. Because the lamp has no fixed “base” orientation the object can be nudged, tilted or rotated to change character and beam direction — interaction that feels immediate, intuitive and tactile. This simplicity increases emotional attachment: a lamp you can gently re-pose becomes an active object in daily life rather than a static appliance.
Designer mindset — function, emotion and human scale
Bergne’s thinking for Curl synthesises three priorities: functional clarity (glare shielding, diffuse light), emotional presence (a soft sculptural silhouette), and human scale (easy to move and interact with). He treats the lamp as a small stage: its proportions, weight and tactile switch all contribute to a pleasing user ritual — turning the light on, dimming it, or rotating the diffuser to change warmth. That ritual focus is why seemingly small choices (switch location, material feel, curvature) carry outsized importance in the product’s success.

From sketch to industrial product — the development path
Curl’s path from idea to market followed a pragmatic design engineering loop:
• Concept sketching & form studies — quick maquettes explored how to fold reflector and body into a single shape that still allowed light control.
• Optical and LED engineering — designers worked with Luceplan’s lighting engineers to specify an LED module that could be tuneable in color temperature and pair with an internal diffuser to avoid hotspots.
• Material and mould testing — die-cast aluminium bodies and injection-moulded diffusers were prototyped to validate finish, thickness and thermal performance.
• Ergonomics & interaction tuning — the central dimmer and the lamp’s balance were iterated so users could operate the lamp easily while repositioning it.
• Certification and production validation — thermal, photometric and safety testing completed before scale production and distribution.
This multi-disciplinary loop ensured Curl was both delightful to use and manufacturable at Luceplan’s quality level.
Materials, optics and technical highlights
Curl’s visible materials and technical features are carefully chosen: a die-cast aluminium body provides a solid, weighty feel and precise finish; the reflector/diffuser is injection-moulded technopolymer to shape light softly; and the integrated LED module supports dimming plus adjustable color temperature (warm → cool) through a simple rotation of the diffuser. The dimmer is positioned centrally for tactile access and the lamp’s internal optics produce a wide, even beam suited to reading and ambient light.

Prototyping challenges and how they were solved
Key production and performance challenges included heat management for an integrated LED module, avoiding glare while keeping the object compact, and ensuring consistent finish quality across aluminium castings. The team addressed these by selecting efficient LEDs with low thermal output, int
egrating heat paths into the aluminium body, testing diffuser geometries to eliminate hotspots, and refining die-cast tolerances to preserve the lamp’s refined silhouette at scale. These engineering moves preserved the design intent while meeting safety and longevity targets.
Use cases — where Curl performs best
Curl works beautifully as a bedside lamp, a study or desk lamp, and as sculptural ambient lighting in living rooms or hospitality settings. Its tuneable color temperature and dimming make it versatile: warmer, dimmed light for relaxed evening moods; brighter, cooler white for focused tasks. Because it reads as a small object of art, Curl also performs well in curated retail and showroom environments where form and story are important selling points.

Why juries, buyers and editors like Curl
Curl’s appeal is threefold: a clear conceptual move (join source + reflector), solid technical execution (LED tuneability, dimming, thermal design), and a tactile, human-centred interaction model (rotating diffuser, central switch). These combined attributes explain why lighting editors and specifiers highlight Curl as an example of contemporary lighting that balances novelty with everyday utility.
Presentation tips for product pages and press
To present Curl effectively online or in print: start with a hero image showing its sculptural profile; add a short gif or video that demonstrates rotating the diffuser to change color temperature and dimming; include a technical spec panel (dimensions, LED output, Kelvin range, dimming range, materials); and provide context shots (bedside, desk, lounge) that show scale and mood. This mix communicates both emotion and evidence — a must for lighting products.

Design takeaways — lessons for product teams
- Small gestures matter: a single, well-resolved interaction (rotating diffuser) can make a product memorable.
- Integrate optics early: light behavior determines form and user experience, so work with lighting engineers from day one.
- Prototype materials for finish and thermal performance — look and reliability are equally important.
- Design for ritual: intuitive tactile controls (like a central dimmer) improve daily satisfaction and perceived quality.
