LED Cable
LED Cable – High Quality Waterproof Connector Cable Factory Direct
The LED cable is an essential part of each LED lighting system. It is used to connect power, signal and control components to enable stable current flow and consistent lighting performance.
Whether you are working with single colour LED strips, RGB lighting, or addressable pixel LEDs, using the correct cable helps prevent voltage drop, overheating, and signal failure.
All cables are high-purity tinned copper conductors and premium PVC/TPU insulation, low resistance, long service life. The waterproof series is IP68-rated and performs well in harsh outdoor or underwater environments. We have CE, ROHS and UL certificates and we support OEM/ODM service like custom cable length, connector type and terminal crimping etc. Volume discounts available. Contact us for samples.

How to Choose the Right LED Cable
1. Current Capacity
The cable must support the total current of your LED system. Higher power systems require thicker cables.
2. Wire Gauge
Lower AWG numbers mean thicker wires and lower resistance.
- 22AWG for low-power short runs
- 20AWG for medium installations
- 18AWG or thicker for high power or long distance runs

3. Cable Length
Longer cable runs have more resistance. And give voltage drops. For longer runs, you need a thicker cable.
4. Type of Voltage
In 5V systems, use thicker cables because of higher current. Standard cables can be used and they are better for long runs in 12V and 24V systems.
5. Number of Conductors
The number of conductors depends on the design of the LED strip circuit, not on the type of lighting. Always check the wiring specification before selection.
Common configurations:
2 conductors: For single colour LED strips.
3 conductors: For LED strips with CCT.
4 conductor: For RGB LED strip lighting.
5 conductors: For RGBW LED strips.
Cable vs Connector vs Soldering
The LED cable is flexible, can be run long distances, and carries a high current. It is hand-wired and installed with care, and is best suited for long runs and power distribution.
LED connectors are quick and solderless. They are good for quick and/or temporary connections. They can come loose over time and can only handle lower current.
Soldering is a strong, low resistance, stable connection. It requires skill, time and the right tools. And it is best for permanent and high-reliability setups.

LED Cable Voltage Drop Explained
Voltage drop is one of the most common issues in LED installations. It occurs when electrical resistance reduces the voltage along the cable.
| Effects of voltage drop | How to reduce voltage drop |
| • Reduced brightness • Uneven lighting • Color shift in LED strips | • Use thicker cables • Shorten cable length • Use higher voltage systems (24V or 48V) • Add power injection for long runs |

Frequently Asked Questions
1. What kind of wire is used for LED strip lights?
The right cable depends on the voltage of the LED strip, the power consumption, the distance of installation and the type of control. A single colour LED tape will usually use a 2-conductor cable, but an RGB, RGBW, CCT or addressable LED tape will require more conductors. For long runs and high-current systems, it is recommended to use thicker wire to reduce voltage drop and increase stability.
2. Can you extend an LED strip light with a cable?
Yes, led cable is used to extend the distance between the power supply, controller and LED strip. This allows for more flexibility in installation where the strip can not be installed close to the driver or controller. If you’re using long extensions you may need to use a thicker cable or inject power to avoid voltage drop.
3. What is the difference between the aluminium LED strip and the copper LED strip?
Copper cable is better than aluminium because it has less resistance and better conductivity. Reliable for long range high current LED installations.
4. Do I need to use a waterproof cable for an LED light outdoors?
Yes. Using waterproof cables to power outdoor LED devices can avoid moisture, rainwater and dust entering so as to avoid corrosion and short-circuiting.
5. Can I use a cable that is too thick?
Yes. It is usually safe to use a thicker cable than is necessary and it also helps to reduce voltage drop. Cost is the main downside and a little less flexibility. Most commercial installations use a thicker cable to improve overall system performance.
