Greetings all, I need help in determining if I could build a IR LED with the components I purchased.

I bought a 5W infrared LED that has requires a forward voltage of 1.4V and forward current of 1400ma.

The LED driver I intend to use for the 5W LED requires an 12V DC input and outputs 3~10V DC voltage and 680ma current.

Will this setup work? Also, if i want to control the brightness of the LED, could I simply stick in a potentiometer at the negative terminal of the LED?

Thank you!
