  • 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. 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. Does an LED strip require an LED driver?

    Yes, LED strips usually require a suitable driver to provide the correct voltage and current. Especially for long strips, because they are often composed of multiple small LEDs in series or parallel.

  • 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.
