TROUBLESHOOTING LED DOWNLIGHTS TROUBLESHOOTING LED DOWNLIGHTS Troubleshooting LED Downlights From time to time issues arise with the performance of LED recessed lighting products after installation. Due to the newness of LED technology it can be difficult to diagnose and remedy these problems. Below is a list of problems that may occur, how to diagnose the cause and what the remedy might be: Problem: Flickering or Flashing Possible Cause #1: Incorrect Voltage LED downlights have a specified input voltage. Incorrect voltage to the driver can cause the LED to flicker or to flash on and off. remedy ? Check the input voltage of the driver (Ex: 120V) then check the voltage being delivered to the fixture (Ex: 277V). There may be a mismatch. If possible, replace the driver on the downlight for one with the correct input voltage to match the line voltage or, if that is not an option, install an applicable voltage transformer to the line voltage to achieve the required input voltage for the original fixture. Possible Cause #2: Incompatible Dimmer If the LED downlight was not designed for a particular dimming load or if the driver is not compatible with the dimming control then issues may occur. remedy ? Try bypassing the dimming circuit. If the LED functions normally then an incompatible dimmer or dimming load may be the issue or the driver is not a dimming driver. Consult factory to determine whether the driver is dimmable and, if so, what kind of dimmer is compatible with the driver.
