the 19V doesnt get used, your driver cost per watt just goes up a bit over a fully filled out driver
look at the efficiency curve (im assuming you mean HLG240 which matches the voltage)
100V/119V = 84% load. you can see that youre still pretty far up on the efficiency curve at 84%, lets say 90.5
assuming youre using 2x QB288 (QB304 cant handle 2100 mA), youd actually be at 106.5V which is 89% of load, and close to 91% efficient
draw at wall would be (106.5V x 2.1 A)/0.91 = 246W
if you actually filled the driver out youd be pulling closer to 275W. 90% driver utilization as in your case is pretty good

thx
4 QB304 can handle 2100 right? in parallel
the same question about the hlg 185h c1400
it has voltage 71-143V
so if ill set 3 QB304 in parallel thay will only use 107V max so the watts should be less then 200W right?
im asking this cuz i want to run a setup that will use 500-550W from the wall (ill have 3 setups of hlg 185h c1400 in one tent)
