An LED driver is an electrical device that regulates power to an LED or a string of LEDs. It is a crucial piece to an LED circuit and to operate without one will result in system failure.Using one is very important in preventing damage to your LEDs as the forward voltage (Vf) of a high-power LED changes with temperature.

The LED driver is a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED(s). This helps avoid thermal runaway as the constant current LED driver compensates for the changes in the forward voltage while delivering a constant current to the LED.

Check the Milliamp Rating of Your LEDs

Ensure that the LED lights' milliamp rating is the same as the LED driver's. Amps and milliamps are the units of measurement for electrical current. While LED lights come in a variety of milliamp ratings, the most popular options are 350mA and 700mA.

Check the Wattage of the LED Driver

Ensure that the LED driver's wattage rating is more than or equal to the total wattage of all lights connected to it. For instance, a driver equipped with five 3-watt outdoor strip lights should have a wattage rating of at least 15 watts.

If you're using an LED tape, multiply the length of the tape by the wattage rating per meter. If the tape is powered at 15 watts per meter and the total length is 3 meters, your LED driver should have at least 45 watts.

 

Check the Output Voltage of the LED Driver

The LED light's input voltage and the LED driver's output voltage should be compatible. Check these before connecting them to avoid damage.
