How to tell if an LED driver is bad?

How to Tell if Your LED Driver is Bad - Complete Guide

You can tell an LED driver is bad by observing the lights, which may be flickering, dim, bright, or completely off. You can also diagnose a faulty driver with a multimeter by measuring a lack of voltage, unstable voltage, or no resistance (a short circuit) at the output terminals, especially if the LEDs themselves are working correctly. Other signs of a failing driver include excessive heat, buzzing, or the driver leaking or showing physical damage.

This video demonstrates how to troubleshoot LED drivers and check for a lack of voltage:

Inconsistent or failed lighting: The most common signs are flickering, strobing, or the lights not turning on at all.
Overheating: The driver feels excessively hot to the touch, or its output current is too high.
Audible noise: The driver may produce a buzzing or humming sound.
Physical damage: There is visible damage, such as leaking liquids, to the driver's casing.
Short lifespan: The connected LEDs burn out much faster than expected.

Safety first:
Power off and disconnect the driver from its power source before testing.
Measure output voltage:
Set your multimeter to DC voltage mode. With the power still on, touch the probes to the output terminals. A working driver will show a stable voltage output; a bad one will show zero volts or unstable voltage.
Measure resistance:
Set your multimeter to the resistance (ohms) setting. With the power off, touch the probes to the output terminals. A good driver will show a high resistance. A low resistance or zero reading indicates a short circuit.
Check input voltage and current:
Use the AC voltage setting to test the input side and the DC current setting to measure the output current. Compare these values to the driver's specifications to check for a stable power supply and correct current delivery.

Nov 24, 2020 — A 3.6 watt (or 3.6 VA) transformer can only supply 60 LEDs if each LED is rated at 0.06 watts. So, something is wrong somewhere and this cannot be answered.

1 answer · Top answer: The set rating of 3.6W cannot be right. You need about 30W of power (assuming per lamp 3v - 0.06w you posted is correct). As for the voltage of 31V, it ...
