Constant Current LED Drivers

Constant current drivers are designed to supply a fixed current output. Unless you overload a CC driver, it will always supply this current. All good quality power LEDs will specify an optimal forward current to realise the best performance and best lifetime. 

With contact current driver you can wire several LEDs in series and provided that you do not exceed the constant current driver's maximum power output rating then all the LEDs will be run at the specified forward current. 

The voltage that is output by the constant current driver will be varied so that there is the correct voltage supplied to each LED.  It adjusts the output voltage automatically up and down up to the rated limit.
