Im powering two 3 watt rgb leds with my arduino using a 13.8V/3A power supply. The are the led specs:
Forward Voltage: 2.5V/3.4V
Continuous Forward Current:350/400
Peak Forward Current: 800mA
Max Forward Voltage: 2.8V/3.8V
Would I need a constant current driver even though the leds can source the needed current from the power supply?
