Choosing the Right Wire Gauge for Flexible Neon Lighting Applications

Selecting the appropriate wire American Wire Gauge (AWG) or gauge for your lighting applications is crucial to ensure safety, efficiency, and optimal performance. Wires come in various gauges, each designed for specific purposes. In your lighting projects, such as using our products with 12V, 24V, or 36V, the right wire gauge can make a significant difference. Let's delve into the details to help you choose the right wire gauge for your specific needs:

Understanding Wire Gauge (AWG):

Wire gauge, often represented as AWG, refers to the thickness or diameter of a wire. It's a standardised system used to classify wires based on their cross-sectional area. The lower the AWG number, the thicker and more robust the wire. Conversely, higher AWG numbers indicate thinner wires. Choosing the correct AWG is crucial to ensure your wires can safely carry the required current without overheating or voltage drop.

Factors to Consider:

1. Voltage Rating:

   • Determine the voltage requirements of your lighting system. All our wire at Flexible Neon is able to be used in any of our 12V, 24V, and 36V systems. We recommend, if using outside of specs or products, that you contact Flexible Neon for any assistance. 

2. Current Load:

   • Calculate the maximum current load your lighting components will draw. This is typically specified in the product's technical documentation.
   • Use the following formula to calculate current (I): I = Power (W) / Voltage (V). Ensure your wire can safely carry this current without overheating.

3. Wire Length:

   • Longer wire runs result in higher electrical resistance, which can cause voltage drop. To minimise voltage drop, choose a thicker wire (lower AWG) for longer runs.

4. Ambient Temperature:

   • Consider the environment where your wiring will be installed. High temperatures can affect a wire's ability to carry current safely. Choose a wire with a temperature rating suitable for your installation environment.

5. Wire Material:

   • Copper is the most common material for electrical wiring due to its excellent conductivity. Copper wires are typically used for lighting applications.

6. Voltage Drop Tolerance:

   • Some applications, especially those requiring precise voltage levels, may have strict voltage drop tolerances. Ensure your wire gauge can meet these requirements.

Choosing the Right AWG for Common Lighting Applications:

Here are recommendations for wire gauges based on common lighting applications and voltage levels:

1. 12V Lighting:

   • For shorter runs (up to 6 meters):

     • 0.75mm² (equivalent to approximately 20AWG),
     • 1.0mm² (equivalent to approximately 18AWG),
     • 0.35mm² (equivalent to approximately 22AWG) for distances up to 3 meters,
     • 0.25mm² (equivalent to approximately 24AWG) for distances up to 1.5 meters.

   • For longer runs (up to 15 meters for best performance, beyond, too much voltage drop may occur):

     • 1.5mm² (equivalent to approximately 16AWG) or
     • 1.0mm² (equivalent to approximately 18AWG).

2. 24V Lighting:

   • For shorter runs (up to 6 meters):

     • 0.75mm² (equivalent to approximately 20AWG),
     • 1.0mm² (equivalent to approximately 18AWG),
     • 0.35mm² (equivalent to approximately 22AWG) for distances up to 3 meters,
     • 0.25mm² (equivalent to approximately 24AWG) for distances up to 1.5 meters.

   • For longer runs (up to 15 meters for best performance, beyond, too much voltage drop may occur):

     • 1.5mm² (equivalent to approximately 16AWG),
     • 1.0mm² (equivalent to approximately 18AWG),
     • 0.75mm² (equivalent to approximately 20AWG) if voltage drop is not a critical concern.

3. 36V Lighting:

   • For shorter runs (up to 6 meters):

     • 0.75mm² (equivalent to approximately 20AWG),
     • 0.35mm² (equivalent to approximately 22AWG) for distances up to 3 meters,
     • 0.25mm² (equivalent to approximately 24AWG) for distances up to 1.5 meters.

   • For longer runs (up to 15 meters for best performance, beyond, too much voltage drop may occur):

     • 1.5mm² (equivalent to approximately 16AWG),
     • 1.0mm² (equivalent to approximately 18AWG),
     • 0.75mm² (equivalent to approximately 20AWG) if voltage drop is not a critical concern.

4. Floodlights:

   • Floodlights can vary widely in power consumption. Calculate the current load based on the wattage and voltage of your specific floodlight. Choose the appropriate AWG based on this calculation.

5. Dot less Strip Lights, Fairy Lights, and Festoon Bulbs:

   • These lighting types often have lower power requirements. 18AWG or 20AWG wires are typically sufficient for most installations.

6. Flexible Neon:

   • Flexible Neon may have varying voltage and current requirements depending on the specific product. Refer to the manufacturer's specifications and follow the guidelines provided.

Additional Tips:

• Always check the manufacturer's recommendations for wire gauge in the product's technical documentation. Some lighting products may have specific requirements.
• Consider using a slightly thicker wire (lower AWG) than the calculated minimum if you want to minimise voltage drop and ensure future scalability.
• Please note that these recommendations are based on typical voltage levels and wiring practices. Always check the specific voltage and current requirements of your lighting components and consider factors like wire length and voltage drop to ensure a safe and efficient lighting installation. If in doubt, consulting with a professional electrician or referring to local electrical codes and regulations is advisable.

Conclusion:

Selecting the right wire gauge (AWG) for your lighting projects is essential to ensure safety, efficiency, and optimal performance. Consider factors such as voltage rating, current load, wire length, ambient temperature, and voltage drop tolerance when choosing the appropriate wire gauge. Refer to the recommended wire gauges for common lighting applications mentioned above as a starting point, and always refer to the manufacturer's specifications for specific products. With the right wire gauge, your lighting installations will function reliably and safely.
