1. What is an LED driver for?
The main role of LED drivers is to provide a stable operating current for LEDs. Since LEDs are very sensitive to current, too high a current can cause them to be damaged or their lifespan to be shortened, while too low a current cannot guarantee brightness. Therefore, a suitable driver can ensure that the LED works under safe and efficient conditions.

2. 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. -
3. 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.

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.
