How to Wire an LED Lamp
Connecting LED lights can be done in different ways, depending on the type of lamp and the power supply. There are three common wiring methods: two-end connection, single-end connection, and staggered connection.
The two-end connection is one of the most commonly used methods. It is convenient for wiring and easy to install. Many LED tube manufacturers use this method. In this setup, the two pins of the lamp base are shorted and connected to the internal constant current power supply. This method only requires removing the traditional starter, and the LED will work normally without any issues.
The single-end connection involves leaving one end of the LED lamp unconnected. The other two pins are connected to the constant current driver. There is no direct connection between the two lamp bases. The main advantage of this method is safety—when one end is connected to AC power, the other end remains safe and not charged. When replacing a traditional fluorescent lamp, you need to remove the original starter and replace it with a fuse before installing the LED lamp.

The staggered connection is a more modern wiring method. It requires a specific internal driver design and uses two AC input channels. The biggest benefit of this method is that it allows the starter to function properly. When replacing the lamp, it’s very straightforward and user-friendly.
Is LED Light Wiring Positive or Negative?
Do LED lights have positive and negative wiring? Yes, they do—but it depends on whether your LED is powered by DC or AC. If it's DC, then polarity matters. Current flows easily from the positive terminal to the resistor, but if it goes the other way, it could damage the LED. LEDs are actually light-emitting diodes, which are made of a PN junction formed by p-type and n-type semiconductors. This means current can only flow in one direction, hence the distinction between positive and negative terminals.
Understanding the correct wiring method is essential to ensure the LED functions properly and safely. Whether you're replacing old fluorescent lamps or installing new LED systems, knowing the basics of LED wiring can help you avoid common mistakes and improve efficiency.
