1. What is the difference between an LED driver and a ballast?
LED drivers: Designed specifically for LEDs, they are usually used to adjust the output current to meet the requirements of LEDs.
Ballasts: Traditionally used for fluorescent lamps or other gas discharge lamps, they control the high voltage at startup and limit the operating current. Although some modern electronic ballasts can also provide constant current, their original design and application areas are different from LED drivers. -
2. 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. -
3. Can I run an LED without a driver?
Yes, but additional circuits (such as resistors) are required to limit the current. However, this method is less efficient and difficult to maintain a stable current, which may lead to poor LED performance or shortened life.

4. 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.
