1. How can I tell if an LED driver is broken?

If the LED does not light up or the brightness drops significantly.
The driver is heating abnormally.
There is a distinct burnt smell.
Measure the input and output voltage/current and it does not meet the specification.
Test the status of its internal components through professional equipment.
2. Why do I need to program an LED driver?

Programming is usually for advanced drivers with programmable functions, such as achieving finer dimming control, color adjustment or other intelligent functions. This allows users to customize the behavior of the driver according to specific needs.
3. Can I use an LED light without a driver?

As mentioned before, in theory yes, but in practice it is strongly recommended to use a proper driver to ensure optimal performance and extend life.
4. Are there LED drivers with audio output?

Some high-end LED drivers do have the ability to synchronize with audio signals and change the lighting effects to the rhythm of music. This type of driver is usually used in occasions such as entertainment lighting or stage lighting.
