SOmewhat confusing still. The spec says 0.6w per light with a total current of 14.4W per set. My calculator says that for a 20 LED set (thats what you've got, yes?) the total current would be 20x.6 = 12watts. So the 14.4w would be if the set were 24 LEDs!
So lets err on the side of caution and allow 14.4 watts per set
for 4 sets thats 57.6 watts (you'll need a welding mask if you shine that lot on your desk). My garden floodlight is 10watt and it lights the whole garden.
From the above, and from the photos, the modules are wired in parallel so you'll need a 12 volt constant voltage LED driver that can deliver at least 57.6/12 = 4.8 amps at 12volts DC.
Thats a big driver. You may want to reconsider your module count!
