One Technology. Every Scale.
Silicone neon flex transforms a bare LED strip into a seamless, continuous line of light. The LED strip sits inside a silicone extrusion that diffuses the point light of individual LEDs into an even glow — no hot spots, no visible dots, no harsh shadows. The silicone body is flexible, UV-resistant, and weatherproof, making the same product equally at home in a residential cove reveal and on an exposed exterior facade.
Nucleo supplies seven silicone neon flex profiles covering everything from a 12×12mm compact square for tight ceiling channels all the way to a 50×25mm high-output profile for large-scale architectural work — plus a side-bending variant for tight horizontal curves and a 360° round profile for column wraps and all-direction signage. Every size runs at 24V DC and accepts standard LED strips.
Profile Range
12 × 12 mm
Top BendingThe smallest square profile — fits into narrow ceiling channels, shadow-gap reveals, and furniture grooves where larger profiles won't seat cleanly. Produces a fine, precise line of light ideal for close-range accent work.
- Shadow gap coves
- Ceiling reveals
- Furniture edges
- Stair nosing
16 × 16 mm
Top BendingThe most widely used neon flex profile — versatile enough for interior coves, staircase edges, and architectural reveals, while compact enough to fit standard ceiling channel grooves. A reliable all-rounder for most residential and commercial projects.
- Interior cove lighting
- Staircase lighting
- Wall reveals
- Column wrap
20 × 14 mm
Top BendingA wider, lower-profile rectangle — presents a broader face of light while keeping a reduced height for shallow-channel installations. The wider face produces a more generous light band, visible from greater distances without increasing the channel depth required.
- Wide ceiling coves
- Shallow reveals
- Retail shelf edges
- Outdoor accents
30 × 20 mm
Top BendingThe mid-to-large format — delivers noticeably higher light output than the 16×16mm while remaining manageable in typical architectural cove channels. Popular for hotel corridors, commercial cove lighting, and exterior base-of-wall wash applications where brightness needs to carry across a room or outdoor space.
- Hotel cove lighting
- Commercial interiors
- Exterior wall base
- Large staircase
50 × 25 mm
Top Bending · High OutputThe largest standard profile — produces a substantial band of light visible over long distances. Used for large architectural cove channels, exterior building perimeters, signage lettering at significant scale, and applications where the neon flex itself is a visible design element rather than a concealed source.
- Building facades
- Large cove channels
- Exterior signage
- Architectural feature
12 × 20 mm Side Bending
Side BendingA tall, narrow profile optimised to bend easily along its wide axis — making tight horizontal curves and plan-view corners far simpler to execute than with a standard 3D bending profile. The 20mm height presents a taller face of light, creating a more prominent line visible even in bright environments.
- Tight corner curves
- Circular plan layouts
- Curved reception desks
- Arched openings
22R Round 360°
360° EmissionThe only profile in the range with a circular cross-section — light radiates outward in a full 360° halo from the tube body. Wherever the neon flex needs to be seen from any angle simultaneously — column wraps, pendant hanging, letter outlines, or standalone decorative features — the round profile is the correct choice.
- Column wraps
- Signage letters
- Pendant features
- Decorative hanging
Top Bending vs Side Bending — Choosing the Right Flex
Top Bending profiles (all standard rectangular sizes) flex upward and downward — ideal for following ceiling coves, wall curves, and vertical surface undulations. Use these wherever the profile needs to rise and dip along its length. Side Bending (12×20mm) is optimised for tight horizontal curves — the profile bends easily in the plan view, left and right, making it the correct choice for curved reception counters, arched openings, and any layout that curves in the floor plan.
Size Comparison
| Profile | Width | Height | Bending Type | Emission | Best Scale |
|---|---|---|---|---|---|
| 12 × 12 mm | 12 mm | 12 mm | Top Bending | Front face | Fine / close-range |
| 16 × 16 mm | 16 mm | 16 mm | Top Bending | Front face | Versatile / residential |
| 20 × 14 mm | 20 mm | 14 mm | Top Bending | Front face (wide) | Shallow reveal / wide band |
| 30 × 20 mm | 30 mm | 20 mm | Top Bending | Front face | Commercial / hotel |
| 50 × 25 mm | 50 mm | 25 mm | Top Bending | Front face (large) | Facade / large-scale |
| 12 × 20 mm Side Bend | 12 mm | 20 mm | Side Bending | Front face (tall) | Tight horizontal curves |
| 22R Round 360° | Ø 22 mm | Ø 22 mm | All-axis flex | 360° all-round | Columns / signage / pendant |
22R Round — Light in Every Direction
All rectangular profiles emit primarily from one face. The 22R Round profile emits in a full 360° circle — wrapping a column means every viewing angle sees an even, continuous glow. For signage letter outlines and decorative hanging features, 360° emission creates a luminous object rather than a lit surface. No face is brighter or darker than any other.
