Sorry, I deleted my post because i gave you wrong info. I thought the driver was a constant current driver and it is not.

And how many watts would you like tu run ?

Right my bad. My driver and boards both get quite warm. Have a fan on both of them. I personally wouldn’t be comfortable trying to push much more out of them but I don’t know really. Maybe it’s safe. I’m not sure. I like the rig.

i doubt i need to max them out for veg plants....probably 200 at the most. that's why i was thinking that 240-H driver might be a good choice, for budget's sake without sacrificing IP rating. I'm running some qb132's on a 240-M and it works out great.
edit: if it's prudent to buy a larger driver I would consider it

For that space I would use a maximum of 200 watts. I recommend the following driver for that space
HLG-240H-C1750, it would run each qb96 at 91 watts.

why the HLG-240-C1750? isn't that (1750mA) well below the rated mA of the qb96's?
I was thinking the XLG-240-H would be a good fit, with output current from 2200-6660mA?

Because it gives you the right wattage for the space you have. You could of course run them much stronger but i doubt it would be beneficial in veg.

N/m i just realized, they won't pull more current than that at 200w. I get it!

I have 4 qb132 on a meanwell lrs350-36 and am pushing them about 77 watts each I like it a lot

You also get higher efficiency running them so low.

Any of you guys use lux meter? I have like 38 in the corners 50,000 lux in the middle with all my lights on. About 20-30,000 with the 96s off. (Thinking veg without 96s, flower with them) is 4 qb96 cranked up about 77-80 watts each and a HLG100 in the middle of a 4x4 enough for veg, then add the 2 96s at about 150 watts each. Is that enough for a high yielding run?

I use a phone app. I doubt it gives me the real number but at least i can check that my light distribution is good.

I have 8 qb 132 each set of 4 in a 320h c2100a. Thanks to Tbone. Is he on rollitup ? I only see him in grasscity.

Damn I was wanting to get 4 more mself and male staggered rows of twos or maybe do 4 and 4 For the outer edges and have 2 qb96 in the middle. I don’t know. Like these lights a lot. Very bright.
Tbone only on grasscity I think. He helped me set all my lights up. Good guy

Lights are 30” from canopy. Is that too far away? Feel like if I go much closer I won’t get any spread but I don’t know. Thanks for any help.

Yes he is definitely a good guy. Right know i am working on adding rapidled uv solderless leds to my qb132. i want to do something like this, inspired in Tbone.

First time I've seen someone put additional diodes on a QB.

I keep my qb 132 at about 20 to 24 inches in flowering. My yield was really good and i feel i get better light distribution that way. So i would not bring them much closer.

Tbone did that. He is the guru of quantum boards in grasscity. I only plan to add 1 or 2 uv leds per board. For a total of 35 watts of uv in my 4x4 tent.

So with your XLG-240-M, Did you manually adjust the current to where you wanted it using a multimeter with pos on pos and neg on neg? Or did you just wire it up and were happy with the brightness?
