Controlling high power leds with an adruino

Hello i have two bridgelux led cobs wired in series with one another and am powering it with a meanwell driver that has a constant current of 1.4 Amps and voltage from 72V-143V. I am looking to simply turn them off and on with an arduino but dont know what components i would need and how to connect them in this circuit. The leds will be driven at 1.4 Amps at 68.1 Volts each. if someone could help me figure this out im just not sure how to connect the high voltage powersupply to the arduino.

Based on your description: any arduino and a relay board will be enough.
