What Is LED Neon Flex?

LED neon flex is a flexible linear lighting product in which LEDs are encased in a continuous silicone or PU (polyurethane) body, producing a smooth, even, glowing line of light that replicates the appearance of traditional glass neon, but with the efficiency, safety, durability, and longevity of LED technology. Unlike LED strip lights, which need a separate aluminium profile and diffuser, neon flex is self-contained: the encapsulated body is the housing, diffuser, and environmental seal in one.

Rhea LED Linear neon flex eliminates the fragility, high voltage, mercury content, and energy inefficiency of glass neon, while preserving the seamless, dot-free glow that makes neon a timeless architectural and signage medium. It bends, shapes, and cuts to form letters, logos, curves, and continuous architectural lines that rigid lighting cannot achieve, and Rhea LED Linear’s range extends to IP68 underwater and in-ground applications most neon flex cannot survive.

The Rhea LED Linear Neon Flex Range, Named for Your Application

Rhea LED Linear AquaFlex, IP68 Underwater Neon Flex Fully submersible silicone neon flex for permanent installation in swimming pools, fountains, and water features. Chlorine-resistant, UV-stabilised, rated for continuous submersion. Proven in 8+ years of continuous underwater operation at the St Regis Maldives, the real-world evidence that lab-tested competitors cannot match.

Rhea LED Linear InGroundFlex, In-Ground & Walkable Neon Flex IP67/IP68 neon flex engineered for in-ground installation, pathways, driveways, landscape edges, and architectural ground-lines. Sealed against water ingress and rated for the demands of ground-level installation where drainage, pressure, and foot traffic challenge ordinary neon.

Rhea LED Linear FacadeFlex, IP67 Outdoor Architectural Neon Weather-resistant neon flex for building facades, landscape lighting, and exterior features. UV-stable silicone resists yellowing under sustained sun. Single colour, RGB, and RGBW for dynamic facade installations, in top-bend and side-bend orientations.

Rhea LED Linear CurveFlex, Dual-Bend Neon for Curved Surfaces Side-bend and dual-axis neon flex that grazes curved walls, arches, columns, and organic forms without kinking, the solution for domes, spirals, and sculptural architecture where standard top-bend neon cannot follow the surface.

Rhea LED Linear PixelFlex, Digital Addressable Neon Individually addressable neon flex with DMX512 and SPI control, enabling each segment to change colour independently for chase effects, colour waves, gradients, and programmable animations. Dual protocol: DMX512 for robust outdoor projects, SPI for flexible indoor installations.

Rhea LED Linear SignFlex, Neon Flex for Signage & Channel Letters Compact, bright neon flex optimized for signage, channel letters, logos, and custom illuminated lettering, with a tight minimum bend radius for forming letters and intricate shapes. Available across the full CCT and RGB range to match brand colours precisely.

Silicone vs PU Neon Flex: Which Should You Specify?

Silicone neon flex offers superior UV resistance, wider temperature tolerance, and longer outdoor lifespan. The silicone body resists yellowing, cracking, and degradation under sustained sun, making it the choice for permanent outdoor, in-ground, and underwater installations. Rhea LED Linear uses premium silicone for AquaFlex, InGroundFlex, FacadeFlex, and CurveFlex.

PU (polyurethane) neon flex is a lower-cost option for indoor and short-term outdoor applications where extreme UV exposure is not a factor, delivering the same diffused glow at a more economical price point for signage and temporary installations.

Rhea LED Linear manufactures both, so the choice is driven by environment and budget, not availability.

Step 6: Specify silicone or PU. Silicone for permanent outdoor, in-ground, and underwater. PU for indoor and budget signage.

Frequently Asked Questions

What is the difference between LED neon flex and glass neon? LED neon flex uses LEDs in a flexible silicone or PU body to replicate glass neon’s glow, but runs on safe low voltage (12V/24V) instead of high-voltage transformers, contains no mercury or fragile glass, consumes 60–80% less energy, lasts up to 50,000 hours, and ships and installs without breakage risk. Glass neon needs skilled glass-bending and high-voltage wiring; LED neon flex cuts and connects with simple tools.

Can LED neon flex be used underwater? Only IP68-rated neon flex can be used underwater. Rhea LED Linear AquaFlex is IP68 silicone neon flex for permanent pool, fountain, and water-feature installation, proven in 8+ years of continuous underwater operation at the St Regis Maldives. IP65 and IP67 are NOT suitable for submersion, IP65 is splash-resistant, IP67 handles temporary shallow immersion only.
