Will this Mean Well power these COBs?

I want to power 3x Vero 29 Gen 7 3000K 50.7 V COBs with the Mean Well HLG-320H-C2100B

Will it work? The typical forward voltage on the COB is 50.7 V and the constant current region for the driver is up to 152 V. I attached part of the datasheet for the driver. (My entire problem stems from the mathematical fact that 50.7 * 3 = 152.1 > 152)

yes but possibly at very lightly reduced currents

thats pretty high current for those cobs, i hope you have good active cooling

This is for a secondary tent and will probably only rarely see the watts cranked up. When it's cranked up, I'll put on some fans. For these COBs I have SST X's passive cooling!

Thanks for the message!

i would invert 3 more chips - and drive 2 rows with that driver-
to have better light efficiency, heat management and lower Vf.

That does sound pretty good. I happened to already have two of the COBs sitting around already, and only had to buy one more COB to cover my 2'x4'. Your idea is the perfect upgrade, though, when that time comes--such a sweet light that will be. Thanks for the message @mahiluana
