How to Choose the Right Power Supply for LED Strip Lights

Learn how to select the ideal power supply for your LED strip lights with essential tips and calculations.

7 views

To choose a power supply for LED strip lights, calculate the total wattage by multiplying the strip's wattage per meter by its length. Add a 20% buffer to this total to ensure reliability. For example, if you have 5 meters of a 12W-per-meter strip, you need 72W (5m x 12W + 20%). Finally, match the output voltage of the power supply to your LED strip’s requirements, typically 12V or 24V.
