How to Connect LED Neon Flex: Complete Installation Guide

LED Neon Flex is the modern alternative to traditional glass neon - offering the same vibrant glow with added flexibility, durability, and energy efficiency for both indoor and outdoor installations.

Think of it like this: LED Neon Flex is like a bendable light rope that emits light from all angles (top, bottom, and sides) - perfect for creating custom neon signs, architectural accents, or decorative lighting without the fragility and cost of traditional neon.

📋 WHAT'S IN THIS GUIDE:

Why Choose LED Neon Flex Over Traditional Neon?

360° Light Emission
Light from top, bottom & sides

💪 Shatterproof
No fragile glass tubes

Energy Efficient
Up to 80% less power usage

🎨 Fully Flexible
Bend into any shape needed


🔧 Essential Tools & Equipment

Before starting your installation, gather all necessary tools and components to ensure a smooth, professional finish.

🛠️ Soldering Tools

💡 PRO TIP: Buy 10% extra Neon Flex length to account for cutting mistakes and test connections. It's better to have spare material than run short mid-project!


⚡ Soldering Connection Process

All connections on 6mm & 8mm LED Neon Flex require soldering. You can solder at the cut ends or create mid-length connections by exposing solder points along the strip.

💡 TWO CONNECTION OPTIONS:

  • End connections: Solder directly to exposed copper pads at cut ends
  • Mid-length connections: Cut away silicone edge to expose solder points without cutting through the flex

Step 1: Prepare Your Tools

What you'll need:

Step 2: Prepare the Neon Flex

For end connections:

  • Locate the cutting marks on the strip
  • Make a clean, straight cut at the designated mark
  • Copper solder pads will be exposed at the cut end

For mid-length connections:

  • Carefully cut away a small section of silicone on the edge
  • Expose the solder points without cutting through the flex
  • Keep the main body intact - only remove edge silicone

Step 3: Solder the Connections

Soldering process:

  1. Pre-tin the exposed copper pads with solder
  2. Strip and tin the ends of your connection wires
  3. Hold wire against the pad and apply heat
  4. Allow solder to flow and create a solid joint
  5. Observe polarity markings (+ and -) if present
  6. Let connections cool completely before handling

⚠️ IMPORTANT: Don't overheat the pads - apply heat for just 2-3 seconds to avoid damaging the LEDs

Step 4: Insulate the Connections

Finishing the joints:

  • For indoor use: Cover solder joints with electrical tape or heat shrink tubing
  • For outdoor use: Apply silicone sealant over connections for waterproofing
  • Use end caps on any exposed cut ends to seal the flex
  • Allow any sealants to cure fully before installation

✅ PRO TIP: Test your connections with a multimeter before final installation to ensure proper continuity

Step 5: Final Testing

Before permanent installation:

  • ✓ Check all solder joints are solid and shiny (not dull/cold)
  • ✓ Verify polarity is correct throughout
  • ✓ Test with appropriate voltage power supply
  • ✓ Ensure no exposed conductors are touching
  • ✓ Confirm all sections light evenly

🔌 Choosing the Right Voltage

Voltage Best For Max Run Length Shop Options
12V Shorter runs, automotive, small signs Up to 10m View 12V Options →
24V Long runs, commercial, architectural Up to 50m View 24V Options →

⚠️ IMPORTANT: Always check product specifications before purchasing. Most of our LED Neon Flex requires 24V, but some strips only need 12V. Using incorrect voltage will damage your installation!


🌈 RGB LED Neon Flex Special Instructions

RGB LED Neon Flex follows similar connection steps but has important bending limitations you need to know about.

Standard Neon Flex

Bending capabilities:

  • ✅ 90-degree angles
  • ✅ 180-degree curves
  • ✅ 360-degree knots
  • ✅ Any direction

RGB Neon Flex

Limited bending:

  • ⚠️ Only lateral bending
  • ⚠️ 90-degrees minimum
  • ❌ No tight knots
  • ❌ Follow copper wire direction

💡 RGB TIP: Plan your design with gentle curves rather than sharp angles. For complex RGB installations, consider using corner connectors instead of bending the strip.


🛡️ Safety Tips & Best Practices

Critical Safety Checklist

❌ NEVER:

  • Cut anywhere except designated marks
  • Operate with voltage higher than specified
  • Connect with exposed wires showing
  • Work on live circuits

✅ ALWAYS:

  • Test connections before final installation
  • Use proper waterproofing for outdoor use
  • Allow heated connections to cool fully
  • Double-check voltage requirements
