LED drivers also protect LEDs from voltage or current fluctuations. A change in voltage could cause a change in the current being supplied to the LEDs. LED light output is proportional to its current supply, and LEDs are rated to operate within a certain current range (measured in amps).

The two main types of LED drivers are Constant Voltage and Constant Current to power up the LEDs.

Constant Voltage Drivers are typically used in outdoor fixtures and signs. These LED drivers provide a constant DC voltage output, typically in the 12V LED driver to 24V LED driver range. The LED module is connected parallel, designed to run at a specified voltage. With the aid of a current regulator, the current to the LED is controlled. Constant Voltage LED drivers are the ideal choice for signs due to their ability to connect a wide range of modules in parallel.

Constant Current LED Drivers utilize a different technology that ensures the current sent to the LED module is constant and within a specified voltage range. The driver may power just a single LED module or multiple LED modules within a given fixture. Driver Output Ratings can include output current as well as voltage range. Currents can be rated anywhere from 350mA to 1000-1400mA.

Dimmable LED drivers have made newer LED fixtures even more efficient. Tunable LED drivers are Constant Current LED drivers that have been finely tuned to provide a precise current to the LED module that is less than what the driver is rated for. This is done as a way to adjust light levels while minimizing heat loss.
