Best driver for these cobs

Ok I'm a noob and was gifted some cobs. I am wondering what the best driver option would be to run these. I have 9 total cobs. These ones to be exact.

CREE CXA3050-0000-000N00V427F LED, Warm White, 80 CRI Rating, 100 W, 4545 lm, 1.4 A, 115 °, 2700 K, SMD-2, Round with Flat Top

I know they aren't the best but for free I won't complain. This is my first DYI and I apologize if this has been asked before. From what I understand so far I think I can safely run 5 cobs on a mean well HLG 320H C1400B
Does that seem right to you guys?

Thank you for all your advice in advance

From the specs I see on that chip it's a 37V design so 6 will actually work on that driver so you'll be fine. I suppose getting your feet wet with building is a good start but from a long term viewpoint I'd switch to a more efficient chip~90lm/w is pretty bleak.

As said these were free so I figure if I'm gonna mess some up it might be a good idea to start with these. I'm VERY green and want to absorb as much as I can. Thank you for the input..

It depends on your grow area dimensions and the amount of light/power you want. A Mean Well HLG-320H-36 driving all 9 cobs will give higher efficiency and better light spread than running 6 cobs at 320 watts.

So I can run all 9 with this driver? The grow box will be custom built around these. 9 lights

Yes, but it's still a 320 watt driver. LEDs are more efficient at lower power, 2 cobs at 0.5A gives more light than 1 cob at 1A.

Buy meanwell drivers stay away from cheap no name power supplies. Nothing worse than going to check on your girls and finding out your driver burnt out, your girls are in the dark and you can't go buy a driver a Lowe's or home De-pot
Buy quality, put in the hard work and never stop learning and absorbing and you can go far here.

Yep I spread mine out at 1 cob per square ft driving them middle of road @ 1050 mAh. Makes for a nice even spread no hotspots
