Help me understand drivers! So I can go ahead with my cob build.

Hello everyone first post long time lurker lol. I am looking to upgrade from my mars 300w (135 actual) to a cob setup for my 2×2×4 tent. I have been thinking about running 4 maybe 5 Vero 29 gen 7 d series chips (3000k) on a mean Well hlg 185h-1050b driver. To my understanding the fv of the d series is 36v and the driver puts out 190v dc. So 190/36=5.27 so I can run 5 cobs at 38v each at 1050ma. I watched growmau5's noob video and he says the all the hlg drivers are 200w. My question is how many watts will I be pulling from the wall with this setup. I pay out the add for electricity so I like to know what I'm drawing. Any help is appreciated. Thank you so much.

With 5 Vero 29 Gen7D 3500K cobs at 1050mA you'll be pulling about 200W at the wall and be capable of about 30,000 lumens. Not bad for a 2'x2' tent. Sorry, didn't run the numbers for the 3000K cob but they'll be very close.
