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. Is an LED driver just a power supply?
Not exactly. Although the LED driver does provide power, it is more than just a simple power converter. It also contains complex circuits to accurately control the output voltage and current, and sometimes includes dimming, temperature protection and other functions.

4. Do all LED lights need a driver?
Not all LED lights require independent drivers. Some small or integrated LED lamps may already have built-in driver circuits. However, for most high-power LEDs or applications that require specific current control, using a dedicated driver is very necessary.
