LED Neon Flex
The Look of Vintage Neon — Zero Fragility, Zero High Voltage, Silicone-Flexible in Any Shape
What Is LED Neon Flex?
LED neon flex is a flexible silicone-jacketed LED product that replicates the glowing appearance of classic glass neon tubing — without glass, without toxic gases, without the 3,000–15,000V transformers, and without the inevitable breakage. A dense LED strip inside a translucent silicone extrusion produces a continuous, uniform glow that is visually indistinguishable from real neon at normal viewing distances.
LED Neon Flex vs. Real Glass Neon
Why every new neon installation in India now specifies LED neon flex over hand-blown glass.
✅ LED Neon Flex (Nucleo)
- 12V / 24V DC — no high-voltage transformer needed
- Silicone — unbreakable, flexible, child-safe
- 80% lower power consumption than glass neon
- IP67 waterproof — outdoor use without enclosure
- 50,000 hour lifespan — no gas depletion
- 25mm bend radius — forms any letter or logo
- No UV emission, no mercury, no toxic gases
- Cut-and-connect in the field — no glass bending lab
- Ships safely as coiled reel — no breakage in transit
⚠️ Real Glass Neon
- Requires 3,000–15,000V transformer — shock hazard
- Glass tube — breaks on impact, difficult to repair
- High power draw — expensive to run continuously
- Not weatherproof — requires protective housing outdoors
- 3,000–7,000 hour lifespan — gas eventually depletes
- Must be glass-bent by specialist — slow, expensive
- Contains mercury — disposal is regulated waste
- Custom orders take weeks — no field modification
- Fragile in transit — expensive specialist packaging
Four Profile Types
Different bending directions and face shapes for different applications — choose the profile that fits your project.
Side-Bend
Best for LetteringBends horizontally in the flat plane. 25mm minimum radius. Used for channel letter fills, logo outlines, and 2D signage shapes that require tight curves within a flat design.
Top-Bend
Best for CoveBends vertically — upward and downward curves. 50mm minimum radius. Ideal for ceiling cove profiles, arched window surrounds, and vertical architectural outlines on building façades.
360° Round
Most FlexibleCircular cross-section bends in all planes simultaneously. For 3D sculptural signage, helix installations, and complex curving forms that need movement in multiple directions.
Square / Flat-Top
ArchitecturalFlat emitting face with square body profile. Clean straight lines for architectural cove applications, bar countertops, and geometric signage where a sharp-edged light is required.
20+ Colour Options
Single-colour, RGB colour-changing, and CCT tuneable variants — any aesthetic is achievable.
Why Choose Nucleo LED Neon Flex?
25mm Bend Radius
Side-bend profile achieves 25mm minimum radius — tight enough for small-font lettering, cursive scripts, and detailed logo curves that glass neon cannot replicate economically.
IP67 Waterproof
Silicone jacket withstands temporary submersion. Fully outdoor-rated for signage, building outlines, and garden features without any additional protective housing.
20+ Colours
Single-colour, RGB colour-changing (with remote), and CCT tuneable variants. Any brand colour reproducible — including custom RAL-matched translucent silicone jackets on request.
50,000 Hours
LED chip lifespan far exceeds glass neon's 3,000–7,000 hours. No gas depletion, no dimming over time. Remains at original brightness for the full rated life.
Field-Cuttable
Cut at marked intervals with a sharp craft knife. Seal with silicone end cap — IP67 maintained at cut points. No specialist glass-bending lab or minimum order required.
80% Less Power
LED neon flex consumes 8–14W/m versus 40–60W/m for equivalent glass neon. For a 10-metre sign running 12 hours/day, this saves approximately ₹15,000–20,000/year in electricity.
Technical Features
🔌 12V / 24V DC
Safe low-voltage operation. No specialist electrician required for most signage and display applications. Compatible with all standard LED drivers.
🎚️ Dimmable
PWM dimmable with any compatible CV dimmer or driver. Smooth dimming from 100% to near-off — no flicker or colour shift at low brightness levels.
🌡️ Wide Temperature
Silicone jacket rated –40°C to +80°C. Operates in extreme outdoor conditions without cracking, yellowing, or loss of flexibility.
📏 Uniform Glow
High-density LED chip spacing (480 chips/m in COB variant) ensures zero visible hot spots even at close viewing distances — true neon appearance.
🔗 Clip Mounting
Snap-in mounting clips every 150mm for walls and flat surfaces. Aluminium backing channels available for recessed cove and signage channel integration.
🎭 Custom Shapes
Neon flex aluminium bending channels allow pre-formed letter shapes. Supply flat-cut acrylic letter templates + neon flex to any sign-maker in India for rapid production.

Installation Guide
🪧 Signage / Lettering Installation
- Create or commission an acrylic or aluminium backing board cut to the letter/logo shape. Mark the neon flex routing path on the board with a pencil — plan the continuous single-run path that minimises cuts and joins.
- Cut the neon flex at the planned cut points using a sharp craft knife or hacksaw. Each cut must be square and clean — angled cuts prevent the end cap from seating correctly.
- Immediately seal cut ends with the silicone end cap and apply clear silicone sealant around the joint. This maintains IP67 — skip this step and moisture enters the LED strip inside.
- Mount clip anchors on the backing board at 150mm intervals along the routing path. Snap the neon flex into the clips — it should sit flush and uniform. For tight letter curves, use additional clips at 50mm intervals.
- Connect each neon flex section to the 12V/24V driver using push-in wire connectors. For multi-section signs, daisy-chain sections in parallel (not series) — all sections share the same +V and GND rails.
- Mount the completed sign board to the wall or hang structure. Conceal the driver and wiring in the sign housing or a weatherproof enclosure. Power on and verify uniform glow across all sections.
🏛️ Cove / Architectural Installation
- Prepare the cove channel or surface groove that will house the neon flex. The channel should be at least 5mm wider than the neon flex profile width and deep enough to recess the flex to the desired exposure depth.
- For top-bend profile in ceiling coves: pre-form the flex to the required curve radius by gently bending the reel before installation. Silicone has memory — hold the curve for 30 seconds before releasing.
- Apply a bead of neutral-cure silicone to the back face of the neon flex at 300mm intervals. Press firmly into the cove channel. Alternatively, use the clip-mount system if the cove surface allows clip fixing.
- Run the 24V DC power cable from the driver position to the start of the neon flex run inside the cove. Use cable conduit within the ceiling void. Strip 10mm of sheath from the flex connection point.
- Connect to the 24V CV driver with the push-in connector or bare-wire terminal. For runs over 8m, inject power at both ends (dual-feed) to maintain brightness consistency throughout the cove perimeter.
- Power on and assess the cove illumination. Adjust any sections that have lifted from the channel surface. Once satisfied, seal any remaining gaps in the cove channel with matching filler or plaster to create a clean shadow gap reveal.
✨ The Glow That Makes a Room Remember Itself
Neon has always been more than lighting — it is mood, memory, and character distilled into a glowing line. The problem was never the look. It was everything else: the fragility, the high voltage, the cost, the maintenance, the fact that one breakage meant weeks of repair by a specialist. LED neon flex removes every one of those constraints while keeping the only thing that ever mattered: the glow.
Nucleo's neon flex range is built for designers who want the neon aesthetic without the neon anxiety — for bars that want their logo on the wall and hospitality operators who want their brand to glow, for homeowners who want their name above their door and retailers who want their window to stop people in the street. Flexible, waterproof, in any colour, cut to any length — delivered Pan India.
