Frequently Asked Questions

What is an LED driver?

An LED driver is the essential power supply for modern, energy-efficient LED lighting. It converts your building's high-voltage AC power into the low-voltage DC power that LEDs need to operate. It regulates the power, protecting the sensitive LED chips from fluctuations that could cause them to flicker or fail prematurely.

What is a light ballast?

A light ballast is the traditional power supply for fluorescent and HID (High-Intensity Discharge) lamps. If you have older tube lighting, you have a ballast. It provides a burst of high voltage to get the lamp started and then controls the electrical current to keep it running steadily.

How do I choose the right wattage for my LED driver?

To ensure safety and longevity, it's best to follow the "80% Rule." Add up the total wattage of all the lights you will connect to the driver, then choose a driver with a maximum wattage rating that is at least 20% higher. For example, if your lights total 80 watts, you should select an LED driver rated for 100 watts or more.

What is the difference between a constant current and a constant voltage driver?

The key difference is what they keep stable. A constant current driver maintains a fixed output current (e.g., 700mA) while letting the voltage change. A constant voltage driver maintains a fixed output voltage (e.g., 12V or 24V) while the current varies. Use constant current for high-power LEDs and constant voltage for fixtures like LED strip lights.

How do I know if I need to replace my fluorescent light ballast?

Common signs of a failing light ballast include your lights flickering, making an audible humming or buzzing sound, taking a long time to turn on, or not turning on at all. If you've already tried replacing the bulbs and the problem persists, the ballast is the most likely cause.
