How to install LED Neon Flex lighting

If you're looking to create impactful signage or exciting décor for your business or home, LED Neon Flex kits are a great option.

After buying your LED Neon Flex kit, it needs to be assembled and installed, so we've provided all the information you need to make installation quick and easy. Neon Flex kits are an excellent replacement for traditional glass neon signs and, when assembled properly, can look incredible for years.

In this guide you will find information on:

• What you'll need
• Installing your LED Neon Flex kit
• What to remember during installation

What you'll need

Before installing your lighting, gather all the tools and parts you'll need.

LED Neon Flex Kit Components

The most important items are included in your LED Neon Flex kit:

• LED Neon Flex tube in your chosen length and colour
• Power lead with connector
• End caps and mounting accessories (sized to match your flex)

Mounting Materials

For sign-making projects, you'll typically need:

• Acrylic backing board or mounting surface
• Template or design guide (optional - see alternative methods below)
• Mounting clips sized for your flex, or adhesive

Power supply

You will need a compatible 12V or 24V power supply. Check your kit specifications - some kits include the power supply, while others require separate purchase.

LED Neon Flex uses low power—never more than a 24V connection is required.

Tools and Adhesives

You may need sharp scissors (for cutting flex to length), soldering iron and solder (for power connections), generic superglue for bonding to acrylic, appropriate primer for your chosen glue, drill and screwdriver (for hard surface mounting), wire strippers, and silicone sealant (for outdoor installations only).

Installing your LED Neon Flex kit

There isn't one set method for installation - find the approach that works best for your project. Here are the main steps and alternative approaches:

Step 1: Prepare Your Materials

Gather your LED Neon Flex kit components, mounting surface, and tools. Ensure you have the correct size end caps and mounting accessories for your specific flex.

Step 2: Choose Your Mounting Method

Template Method: Create a template or mark out your design on the mounting surface for accurate placement.

Groove Method (Alternative): Mill a groove in your acrylic backing board, wide enough for the flex to slot into. This eliminates the need for a template and holds the flex in place while you work with it.

Step 3: Position the Flex

Place your LED Neon Flex along your desired path or design. If using the groove method, slot the flex into the milled channels. This allows you to check the layout and make adjustments before securing.

Step 4: Connect the Power Lead

Carefully connect the power lead to your LED Neon Flex through soldering. Ensure all connections are secure and properly insulated before proceeding.

Step 5: Bond to the Surface

Apply primer if using (different glues have different primers - check your adhesive specifications). Bond the LED Neon Flex to your acrylic surface using generic superglue. The primer will help the glue work more quickly and effectively.

Step 6: Fit End Caps and Mounting Accessories

Install the appropriate size end caps and mounting clips for your flex. Ensure they're properly fitted and secure.

Step 7: Seal Connections (Outdoor Signs Only)

For outdoor installations only, seal all connection points with silicone sealant to prevent moisture ingress. This step is not necessary for indoor installations.

Step 8: Test Your Installation

Connect your power supply and test the installation. Check that all sections illuminate evenly and connections are secure.

What to remember during installation

Although easier than traditional glass neon, keep these points in mind:

• Always keep the strip facing outward with no twists—twisting breaks the even light spread and can damage the tube.
• Avoid sharp bends; use gentle curves to prevent damage. Complex designs may require creating a template or consulting a professional.
• Cut only at designated cutting points (marked lines) to avoid damaging internal wiring.
• Ensure you select the correct size accessories for your specific flex dimensions.
• Verify you're using the correct power supply voltage, and double-check all connections before powering up.
• Connection sealing is only required for outdoor installations.
• Once bonded with superglue, repositioning becomes difficult, so plan your layout carefully.

Follow these steps and your LED Neon Flex kit installation will look stunning and last for years—whether it's for a restaurant sign, home accent, or retail display. Remember, there isn't one set method - experiment and find the approach that works best for your specific project.
