Neon Flex & LED Flex Guide
Neon Flex (also called LED Flex or Flexible Neon) is a modern alternative to traditional neon — offering flexible, energy-efficient, and durable lighting for signage, architecture, and design.
In this guide, we’ll explore:
- The 3 main types of LED flex based on bending direction
- Use cases, advantages & disadvantages
- Mounting tips and compatibility notes
➰ 1. Types of Neon Flex
🔹 Front-Bend (Top-Bend)
Bends in the vertical direction — like folding a ribbon up/down.
This type emits light from the top (flat surface).
| ✅ Best For | ⚠️ Not Ideal For |
|---|---|
| Text signs, curves, vertical loops | Side-facing applications |
| Wall lettering, channel letters | Corners that bend sideways |
🔸 Side-Bend (Lateral-Bend)
Bends horizontally — like wrapping around a column.
Emits light from the side surface.
| ✅ Best For | ⚠️ Not Ideal For |
|---|---|
| Outlines, signs, edge lighting | Vertical curves or loops |
| Following letter contours | Front-facing glow needed |
🟢 3D-Bend (Triaxial Flex)
Bends in both directions — horizontal and vertical.
Some advanced types also twist slightly.
| ✅ Best For | ⚠️ Not Ideal For |
|---|---|
| Complex shapes, logos, art | Sharp corners or flat-only designs |
| Sculptural or architectural | Price-sensitive projects |
🧠 Summary Table
| Type | Light Direction | Bends | Use Case Example |
|---|---|---|---|
| Front-Bend | Top / upward | Vertical | Wall lettering, signage |
| Side-Bend | Sideways | Horizontal | Edge outlines, curved signs |
| 3D-Bend | Top / sides | 3D flex | Sculptural lighting, logos |
✅ Advantages of LED Neon Flex
- Durable: Silicone/PVC casing is weather-resistant
- Flexible: Can follow complex curves and shapes
- Low Voltage: Safe and easy to power (12V or 24V)
- No Glass or Gas: Unlike traditional neon
- Uniform Glow: Dot-free light diffusion
- Custom Cuttable: Usually every 2.5–10 cm
⚠️ Disadvantages
- Limited Sharp Bends: Can kink or damage if bent too tightly
- Fixed Colors (in some types): RGB/W not always available
- Cut Restrictions: Only cut at marked intervals
- Dimming & Control: Requires compatible drivers/controllers
🔧 Mounting & Compatibility Tips
- Use mounting tracks or aluminum channels for precise placement
- Always test-bend before installation to ensure fit
- Avoid twisting flex in unsupported directions
- Check bend direction before cutting or ordering
- Compatible with DMX, SPI, or PWM control depending on model
💡 Popular Applications
| Application | Flex Type |
|---|---|
| Channel letters | Front-Bend |
| Logo outlines | Side-Bend |
| Artistic installs | 3D-Bend |
| Retail signage | Front-Bend |
| Cove lighting | Side-Bend or Front-Bend |
📦 Product Selection Notes
When choosing a Neon Flex model, consider:
- Voltage (12V vs 24V)
- Wattage per meter
- Color or RGB capability
- Bending direction
- IP Rating (indoor vs outdoor)
