Shunted vs. Non-Shunted Lamp Holders

The difference lies in the electrical connection within the lamp holder itself. Shunted lamp holders have a short (shunt) between the contacts, allowing the electrical current to pass through a single path.

They are typically used with fluorescent tubes that operate with a ballast. Non-shunted lamp holders, on the other hand, have separate contacts that do not connect internally, creating two distinct paths for the electrical current. This type is required for most direct wire LED tube installations, where the tube is wired directly to the power source without a ballast.

Using the wrong type of lamp holder can prevent LED tubes from lighting up or cause them to malfunction. For instance, installing a direct wire LED tube into shunted lamp holders without removing or bypassing the ballast can lead to electrical shorts and potentially damage the LED tube.

Overlooking Ballast Compatibility

A frequent mistake in LED tube installation errors is neglecting to consider the compatibility between the LED tubes and the existing lighting fixture’s ballast. This oversight can lead to a range of issues, from non-functional lighting to unnecessary energy consumption.

Understanding the distinction between direct wire and ballast compatible LED tubes, as well as knowing how to correctly remove or bypass a ballast, is essential for a successful installation.

Direct Wire vs. Ballast Compatible Tubes

LED tubes mainly come in two types based on how you install them: direct wire (ballast bypass) and ballast compatible. Direct wire LED tubes need you to remove or bypass the old fluorescent ballast, letting you connect the tube straight to the power source.

People often prefer this for its reliability and energy efficiency, as it avoids compatibility issues and the energy used by a ballast.

Ballast compatible LED tubes, however, can work with the existing fluorescent ballast. This plug-and-play method makes installation easy because you can just put the LED tubes into the current fixture without changing the wiring.

However, this convenience can come at the cost of compatibility issues, as not all LED tubes may work with every type of ballast, leading to potential operational issues.

Common errors include not verifying the type of LED tube and its compatibility with the existing ballast, resulting in flickering lights, reduced lifespan of the LED tube, or complete installation failure.

Removing or Bypassing the Ballast

For direct wire LED tube installations, removing or bypassing the ballast is a crucial step.

Here’s a simplified guide to safely accomplish this:

  1. Safety First: Ensure the power is turned off at the circuit breaker. Verify with a non-contact voltage tester.
  2. Access the Ballast: Open the fixture cover to expose the ballast and wiring.
  3. Disconnect the Ballast: Cut the wires connected to the ballast, leaving enough length for rewiring to the power source. Remove the ballast from the fixture.
  4. Rewire the Fixture: Connect the power source directly to the lamp holders. For single-ended tubes, ensure that the live (hot) and neutral wires are connected to the correct end of the fixture. For dual-ended tubes, connect live and neutral wires to both ends as per the manufacturer’s instructions.
  5. Secure Connections: Use wire nuts to secure the connections and electrical tape to insulate them.

Eliminating the ballast reduces energy consumption and maintenance costs, as ballasts can fail over time and are not needed for LED operation. This approach also avoids compatibility issues, ensuring a smoother and more efficient lighting system.
