Frequently Asked Questions

Frequently Asked Questions

1. What accessories do I require for a basic installation and how do I connect them?

For a general or basic 12V SMD RGB LED Strip Light installation, you would require:

1 × 12V DC Power Supply & Power Cord
1 × RGB Controller
12V SMD RGB LED Strip Light
Compatible RGB Cable and Connectors

See the installation diagram for guidance on the correct connection method.

2. Are there any other items or optional extras that I may need?

Depending on your application, you may also need:

Aluminium LED Profiles
Insulated 2-Core Flex to extend the cable between the Power Supply and Strip Light
4-Core RGB Cable for connecting the controller to the Strip Light
RGB Connectors or Terminal Blocks
Mounting clips or brackets
Additional double-sided adhesive tape
Soldering supplies and heat shrink tubing for custom connections

3. What Voltage Power Supply would I use?

Always use a Power Supply with the same voltage as the Strip Light.

For a 12V SMD RGB Strip Light:

12V Strip Light → 12V DC Power Supply

Never connect a 12V LED Strip Light directly to 230V AC mains power.

4. What size Power Supply would I need?

Calculate the required power using:

Strip Light Length (M) × Power (Watts/M) + 15%

Example:

5M × 10 Watts/M = 50 Watts
50 Watts + 15% = 57.5 Watts

Therefore, a 60W or 75W 12V Power Supply would be sufficient.

For additional headroom and long-term reliability, a slightly larger correctly rated power supply can be selected.

5. What are the benefits of installing Aluminium Profiles?

Aluminium Profiles help to:

Conceal wiring and create a cleaner installation
Act as an additional heat sink
Protect the LED strip from accidental damage and dust
Provide a professional, finished appearance
Help improve the lifespan and performance of the LED Strip Light

When using SMD RGB Strip Lights, an aluminium profile also helps create a neat, professional installation while improving heat dissipation.

6. Can I install 12V SMD RGB LED Strip Lights myself?

Yes. The low-voltage side of a 12V LED Strip Light installation is relatively straightforward when using compatible components.

However, any connection of the Power Supply to 230V AC mains electricity should be completed according to local electrical regulations. If you are unsure, consult a qualified electrician.

7. Do you have DIY Kits with everything included?

Yes. We have a variety of DIY Kits designed to simplify LED Strip Light installations and include easy-to-follow instructions for basic applications.

For RGB installations, ensure the kit includes a compatible RGB controller and the required RGB connections.

8. Can I shock myself?

The 12V DC output side of the Power Supply is low voltage, so the risk of a dangerous electric shock under normal conditions is significantly lower than with mains electricity.

However, the 230V AC input side of the Power Supply is dangerous. Always complete and check the low-voltage and RGB connections before connecting the Power Supply to mains electricity.

9. Can 12V SMD RGB Strip Lights bend around corners or curved shapes?

12V SMD RGB LED Strip Lights are flexible and can be used for many curved and decorative applications.

However, they should not be sharply bent, folded or twisted. Always follow the manufacturer's recommended bending radius and avoid putting excessive stress on the PCB, LEDs, or solder joints.

10. Can I cut the Strip Lights?

Yes. 12V SMD RGB LED Strip Lights can be cut at their designated cut points.

Always cut directly along the marked cut line using suitable scissors or a sharp blade. Cutting anywhere else may damage the circuit or cause sections of the strip to stop working.

After cutting, ensure the power and RGB connections are correctly reconnected before operating the strip.

For hassle-free installations, our Cut & Solder Customising Service can cut the Strip Lights to your required lengths, solder the connections and test them before installation.

11. How are the Strip Lights mounted?

The Strip Lights feature double-sided adhesive backing for quick and convenient mounting onto a clean, smooth and dry surface.

For a more secure and professional installation, an Aluminium LED Profile or suitable mounting system is recommended where applicable.

12. Can they be dimmed and colour controlled?

Yes. 12V SMD RGB LED Strip Lights can be dimmed and colour controlled using a compatible RGB controller.

Depending on the specific controller, RGB control can provide brightness adjustment, colour selection, colour-changing effects, and dynamic lighting programmes.

The RGB controller and power supply must be correctly rated and connected according to the manufacturer's wiring instructions.

Installation & Setup

12V SMD RGB LED Strip Light Installation & Setup

Installing a 12V SMD RGB LED Strip Light is straightforward when the correct components are used.

Step 1: Plan Your Installation

Measure the installation area, determine the total strip length required, and calculate the total wattage to select a suitable 12V DC power supply with at least 20% spare capacity. Plan the RGB controller and cable routing before installation.

Step 2: Prepare the Mounting Surface

Ensure the surface is clean, dry, and free from dust or grease. For the best performance and longest lifespan, install the strip inside a suitable aluminium LED profile where possible.

Step 3: Cut the Strip (If Required)

Only cut the LED strip at the marked cut points. Cutting elsewhere may damage the strip or prevent sections from operating correctly.

Step 4: Connect the Strip

Connect the strip to the 12V DC power supply and compatible RGB controller using suitable connectors or by soldering wires to the designated connection pads. Always observe the correct power polarity (+ and –) and ensure the RGB connections are correctly wired.

Step 5: Test Before Mounting

Power the system briefly to confirm that the strip illuminates correctly and that the RGB controller can select colours, adjust brightness, and operate the required colour-changing effects before permanently fixing it in place.

Step 6: Secure the Strip

Remove the adhesive backing and press the strip firmly onto the mounting surface or into the aluminium profile. Avoid excessive bending, twisting, or folding during installation.

Step 7: Connect to Power & RGB Control

Connect the 12V power supply to the mains according to local electrical regulations and connect the RGB controller according to the manufacturer's instructions. If you're unsure about mains wiring, consult a qualified electrician.

Installation Tips

Avoid sharp bends and do not exceed the minimum bend radius.
Use aluminium profiles where possible to improve heat dissipation and protect the LED strip.
For longer installations, use appropriate power injection points to help minimize voltage drop.
Ensure the RGB controller and connections are correctly wired for reliable colour control.
Do not power the strip while it is still tightly wound on the reel.
Choose an IP-rated strip suitable for the installation environment, especially in damp or outdoor locations.
Ensure all power and RGB connections are secure and properly insulated.
Always test the colours, brightness, and RGB effects before permanently mounting the strip.

Following these steps will help ensure reliable performance, consistent illumination, accurate colour control, and a long service life from your 12V SMD RGB LED Strip Light installation.
