How will I know whether to use a Constant Voltage or constant current Led driver Led driver
Usually the manufacturer of the LED module will specify whether it is for use with either a Constant Voltage or Constant Current driver.
You cannot run an LED module designed for CC from a CV supply without damaging it.
However a CV LED load will run (albeit inefficiently) from a CC driver.
Another indication is if the LED module is rated in milliamps (mA) or volts (V). Milliamps indicates a CC driver and Volts means a CV driver is required.
