Constant Current LED Drivers

A constant current LED driver delivers a fixed amount of current (often 350mA, 700mA or 1A) to your LED lights while allowing your voltage to vary. The voltage requirements of your LED lighting system should fall within the minimum and maximum voltage range that each constant current LED driver specifies.

When to Use a Constant Current LED Driver

What You Need to Know about LED Drivers

Constant Current LED drivers have two primary purposes: To convert high AC Line voltage to low DC voltage, and to fix the electrical current to your LED.
In simple terms, current is the rate of electricity that is flowing into your light (measured in amps). Too little or too much current effects the light output and reliability of your LEDs. A constant current power supply makes sure that your LEDs have just the right amount of electricity flow that they need. Not too little, not too much. Just right.
In addition to regulating the current, constant current LED drivers have the flexibility of being able to adjust the voltage as needed. As you add more and more LEDs, the voltage output on the driver will incrementally increase up to the maximum voltage. Usually, the LED manufacturer will indicate which type of LED driver you need, but if not, you may be able to check the LED itself to see how it is rated. If it's rated for milliamps or amps (mA or A), you are in the right place. If it's rated for a specific voltage, you may need a 12 Volt or 24 Volt constant voltage driver.
