    Looking for the right Driver to run 12 Luminus CXM22 3500k 90cri Cobs

    You can dim the A-version too, it's just easier with the b-version (attach potentiometer). Yea, i believe the drivers can dim down to 10% of max output. Is it for flower only, or full cycle grow? To be honest, the difference between 3500K and 3000K is marginal. Personally i'm running 3000K...

    Looking for the right Driver to run 12 Luminus CXM22 3500k 90cri Cobs

    They are ~50V cobs. I run 6 of them on this: https://www.meanwell-web.com/en-gb/ac-dc-single-output-led-driver-constant-current-cc-hlg--320h--c1050a They run at a little over 50w each, but you could get the B-version of the driver and dim it a little to hit 45w.

    Buds quality LEDs VS HPS

    Well... It's pretty easy to cool a led fixture passively. No need for any fans, and even fewer watts spent.

    Buds quality LEDs VS HPS

    Can't talk for the states, but in Europe the potential energy savings make more than a lot of difference. We tend to pay quite a lot for electricity compared to U.S, and when you can yield the same for fewer watts used, well then that's rather welcome.

    COB LED 3500k vs. 3000k veg/flower

    cob = chip on board , like Vero, Cree, Luminus and Citizen for instance. strips/boards, as in mid-powered led strips using the same tech as cobs. https://horticulturelightinggroup.com/ Currently, i'm using Cree CXB3590 3000K 80CRI for veg, and Luminus CXM-22 3000K 90CRI for flower. Both could...

    COB LED 3500k vs. 3000k veg/flower

    It's a trade-off with 80 vs 90CRI. Slightly higher output with 80, and better flowering spectrum with 90. A lot of people are moving towards 90CRI with cobs and strips now.

    Buds quality LEDs VS HPS

    That's what usually happens with these guys... First they run out of arguments, then they run out of insults, and finally they declare that they won, lol

    Buds quality LEDs VS HPS

    Yea, sorry 'bout that... I'm scandinavian and we tend to use sarcasm a lot. Also in writing... Let me clarify: It is cheaper up front. And again, if the energy savings in the long run are minimal, then it doesn't make sense (from a business perspective) to make the switch.

    Buds quality LEDs VS HPS

    'cause it's cheaper up front? ...and if you're located in a place where energy costs are low, then so is the incentive to switch to more planet-friendly lights i guess.

    Little help needed...

    That driver is suitable for parallel only. It provides 36v and your cobs need 36v each to power up. When wiring in series, the forward voltage of each cob adds together, so in your case you'd need 72v from the driver to power up both cobs in series.

    CXB3950 / 36v vs. 72v

    They're identical in output/quality, but your driver options diminish somewhat with the 72v version. You can only run 2 cobs on your driver if it's 72v, and 4 cobs if they're 36v
