PWM driving of high-power LED with an arduino - LEDs and

I need to drive 2 red and 2 blue high-power LEDs for an application (LED indicated below). First of all, I connected the LEDs directly to the 12V power supply and measured the currents they draw. As you can see, the red one draws about 1.4A. As you can see, the blue one draws about 0.5A. My question is that I want to use MOSFET to drive these LEDs with PWM, I have shared two circuits below which should I use?Why? Circuit-1 Circuit-2
