How to Maintain and Clean LED Light Tubes for Maximum Efficiency

By  //  March 21, 2025

LED light tubes are an affordable and energy-efficient lighting solution. However, to be sure they perform at their peak and last as long as possible, proper maintenance and regular cleaning are essential. Dust, dirt, and other contaminants can accumulate over time, reducing their brightness and efficiency. 

Here’s how to maintain and clean your LED light tubes effectively.

Why Regular Maintenance is Important

LED light tubes and a LED light diffuser have a long lifespan, often lasting up to 50,000 hours. However, their performance can degrade if they are not maintained properly. Dust and grime on the surface can block light output, reducing brightness and energy efficiency.

Poor maintenance can also lead to overheating, which can shorten the lifespan of the LED components. Regular cleaning and inspection can help prevent these issues and keep your lights running efficiently.

Precautions Before Cleaning

Before you begin cleaning LED light tubes and LED light diffuser, safety should be your top priority. Follow these precautions:

  • Turn off the power – Always switch off the light and unplug the fixture if possible. This prevents electrical shocks and reduces the risk of damaging the light.
  • Allow the lights to cool – LED tubes generate some heat, and handling them immediately after switching them off can cause burns. Wait a few minutes for them to cool down.
  • Use a sturdy ladder – If the LED tube is installed in a high place, use a stable ladder or step stool to reach it safely.
  • Avoid harsh chemicals – Strong cleaning agents can damage the protective coating on LED tubes, so it’s best to use mild cleaning solutions.

Step-by-Step Cleaning Process

Remove the LED Tube (if necessary)

  • If your LED tube is easily detachable, carefully remove it from the fixture. If it is integrated into a fixture, you will need to clean it while it remains in place.

Dust Off the Surface

  • Use a dry microfiber cloth or a feather duster to wipe off any loose dust. Avoid using rough or abrasive materials that could scratch the surface.

Wipe with a Damp Cloth

  • Lightly dampen a soft cloth with a mixture of water and a small amount of mild dish soap.
  • Gently wipe the LED tube, making sure not to let any liquid seep into electrical connections.

Dry Immediately

  • Use a dry microfiber cloth to remove any moisture, ensuring no water spots are left on the surface.

Clean the Fixture and Surroundings

  • Dust and dirt can accumulate in the fixture and surrounding areas, so it’s important to clean them as well to prevent further contamination.

Reinstall and Test

  • If you removed the LED tube, place it back in the fixture securely.
  • Turn the power back on and check that the light is functioning properly.

Additional Maintenance Tips

  • Inspect for Damage – Regularly check for flickering, dimming, or discoloration, which may indicate issues with the tube or fixture.
  • Avoid Frequent Switching – Turning LED tubes on and off frequently can reduce their lifespan, so try to minimize unnecessary switching.
  • Ensure Proper Ventilation – Overheating can reduce LED efficiency, so make sure the fixture allows for proper airflow.

By following these steps, you can keep your LED light tubes clean and bright for years to come.
