  • Replace the Driver with a Compatible Model if Needed: If the driver is the problem, replace it with a new, compatible model. Make sure the new driver matches the light’s specifications, including voltage and wattage, to avoid further issues.

By verifying the wiring and testing the LED driver, you can troubleshoot and fix issues with round high bay LED lights that aren’t turning on. Proper diagnosis and repair will restore the lights to optimal functioning, ensuring bright and effective illumination for your gymnasium or other spaces.


Overheating is a common issue with round high bay LED lights and can significantly reduce their lifespan or performance. Proper ventilation and power management are key to preventing overheating.  Check for Ventilation Issues: LED lights generate heat, and without adequate ventilation, they can overheat.  

  • Ensure the Fixtures Have Adequate Airflow: Make sure the light fixtures are installed in a way that allows for proper airflow. Crowded or enclosed installations can trap heat, leading to overheating. Clear any obstructions and ensure the lights have sufficient space for cooling.  
  • Adjust or Reposition the Lights for Better Ventilation: If the lights are overheating due to poor ventilation, try adjusting or repositioning them to improve airflow. This might involve changing the orientation of the fixtures or moving them to a more open area where they can cool down effectively.  

Ensure Fixtures Aren’t Overloaded: Overloading the fixtures can also cause them to overheat, as excessive power can strain the components.  

  • Check the Power Ratings and Adjust if Overloaded: Verify that the power ratings of the fixtures match the power supply. If the fixtures are overloaded, reduce the power input or upgrade to higher-rated fixtures that can handle the electrical load.  
  • Use Appropriate Drivers and Power Supplies for the Lights: The power supplies and drivers should match the requirements of the LED lights. Using inappropriate or mismatched components can lead to overheating. Ensure that the drivers and power supplies are compatible with the lights’ specifications to prevent overloading and overheating.
