You will need a constant current LED driver to regulate current between your power supply and high-power LED. The LED driver will convert your power supply to constant current with a varying voltage suitable for LED lights ( mostly 12V or 24V ), while not allowing the current to exceed the maximum current rating of the LED. This will protect your LED and make sure it is getting the power it needs.
Our power supply and driver selection contains constant current drivers with a wide range of outputs as well as drivers and components for dimming and non-dimming applications. We offer LED drivers from top brands like MeanWell.
