1. Understanding Power Requirements

Accurately determining the power needs of your LED setup is the foundation of proper driver selection. Most reputable luminaire manufacturers provide detailed electrical specifications, including required voltage, current, and wattage. If this information is unavailable, you can calculate the power draw manually:

• Measure the forward current (in milliamps) and forward voltage (in volts) of the LED module using a multimeter.
• Multiply the two values: Power (Watts) = Voltage (V) × Current (A).
• Divide the result by 1000 if current was measured in milliamps (mA).

For example: 24V × 0.625A = 15W.

To simplify integration, many business buyers opt for constant voltage drivers—typically 12V or 24V DC outputs—which are ideal for powering multiple 15W LED strips or modules in parallel. These drivers maintain a steady voltage output, making them suitable for consistent lighting applications where brightness control isn’t critical.

Pro Tip: When using constant voltage drivers, ensure the total load does not exceed 80% of the driver’s maximum rated capacity to allow for thermal derating and extend lifespan.
