Silicone Neon Flex & Strip: The Modern Replacement for Glass Neon
LED neon flex — also called flexible neon, neon rope light, ou silicone neon strip — is a flexible silicone tube with SMD LEDs sealed inside. The diffused silicone produces a continuous, dot-free glow that looks nearly identical to hand-bent glass neon, without the glass, gas or high-voltage transformer.
Because it runs on safe low voltage, neon flex is brighter, tougher and roughly 80% more energy-efficient than glass neon — which is why sign makers and lighting designers now specify it for channel letters, building outlines and outdoor decoration.
LED Neon Flex & Strip by Bend & Emission
Match the bend direction and emission face to your sign or outline. Helian covers top bend, side bend, 3D bend, 360° round, two-sided, side-view, top-view and standard profiles — plus high-voltage AC and RGB addressable lines.
Top Bend Neon Flex
Bends vertically (up and down) for letterforms, logos and building outlines that need a clean upright glow line.
View Top Bend Models
Side Bend Neon Flex
Bends horizontally (left to right) for facades, walls and signage where the strip follows the surface plane.

Integrated extrusion seals out rain, dust and salt spray. IP68 models handle permanent submersion.
Uniform Dotless Glow
Opal silicone diffusion produces a smooth, continuous light line with no visible LED dots or hot spots.
24V & High-Voltage AC
24V DC for safe long runs; high-voltage AC for direct mains use with no power supply needed.
RGB / RGBW / Addressable
Single color, constant-current RGB/RGBW, DMX512 pixel, SPI and Bluetooth control for chasing and dynamic effects.
Cuttable & Bendable
Marked cut points, 25–50mm bend radius, and full accessory system — end caps, clips, connectors.
Stable Batch Quality
±3% color consistency and 100% pre-shipment inspection — no batch difference for repeat orders.
3-Year Warranty
CE & RoHS certified, 30,000–50,000 hour rated life, factory-direct with 3–7 day bulk lead time.

* Bend direction and emission face are independent — a strip can be top-bend or side-bend while emitting from its top, side or multiple faces. Standard series uses a top emission face with horizontal-only bending. High-voltage AC models run at AC230V (220–240V) for direct mains connection with no power supply. Custom sizes, CCT and control on request.

Neon flex fails at the cut end — so we supply the accessories and guidance to keep every run waterproof.
Marked Cut Points
Cut only at the marked intervals (typically 25–50mm) for a clean, reconnectable end. Clean perpendicular cuts give the end cap a flat sealing surface.
Seal Every Cut End
Fit a matched silicone end cap and bond with neutral-cure RTV sealant. Neutral cure won’t corrode copper — generic acetic sealant will.
Mount & Connect
Snap into aluminum profile or mounting clips, make IP-rated connections, and form drip loops so water never tracks into the driver.

LED Neon Flex — Common Questions
What is LED neon flex and how does it differ from glass neon?
LED neon flex is a flexible silicone tube with SMD LEDs inside, producing a continuous dot-free glow that mimics glass neon without the glass, gas or high-voltage transformer. It runs on safe 24V DC, uses about 80% less energy and lasts 30,000–50,000 hours.
What bend directions are available for LED neon flex?
Helian offers top bend (vertical), side bend (horizontal), 3D bend (both directions), 360° round emitting, two-sided and side-view/top-view profiles, so you can match the bend direction to your sign or building outline.
Is your LED neon flex waterproof for outdoor use?
Yes. Helian silicone neon flex is available in IP65, IP67 and IP68. IP67 suits outdoor rain exposure; IP68 models handle permanent submersion, saunas and harsh coastal conditions.
How do I cut and seal LED neon flex outdoors?
Cut only at the marked cut points, then reseal the exposed end with a matched silicone end cap bonded with neutral-cure RTV sealant. Helian supplies end caps, mounting clips and connectors for a waterproof finish.
Do you offer high-voltage AC and DMX512 addressable neon?
Yes. We offer high-voltage AC neon flex for direct mains use without a power supply, plus DMX512 pixel RGB/RGBW and SPI addressable neon for chasing and dynamic effects.
What is the difference between neon flex and neon rope light?
Neon flex is a flat or shaped silicone extrusion that bends in a defined direction (top, side or 3D), giving a cleaner, brighter, more precise light line. Rope light is a round PVC tube with lower brightness and less color accuracy — fine for DIY décor, but neon flex is what professionals specify for signage and architectural work.
