I Need help Driver Sizing for COB led.

Hello I am trying to build my first light. I have decided to use the Gen 7 Vero 29 , 3500k spectrum, as it seems so offer the best wattage and price point (the next best was 30 watt rated which though would lack intensity for the lower canopy.)

I’m having a hard time sizing the driver so I can run 4 of these off 240w (60w a cob, they’re tested at around 80w).

The specs are
37.7V-69.4V forward voltage
1.7A-2.1A test current. 3.7A-4.2A max.


Edit: I think I’m just going to use this build and order everything through DigiKey as I’m in Canada and amazon doesn’t carry the right components.
