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. 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.
