I have a couple 12 cob 3590 fixtures running at 1400 mah (50 watts each). I would like to replace my drivers for 1750 mah version, will the hlg 240 1750b run 4 36v 3590's? It shows the output voltage at 143 volts, that divided by 4 is 35.75, will this run 4 without issue or is 3 the limit...

So 2 step is better than 3 then lol?

I see mostly -73 vero's available, what is the difference of the -72 variety, is it better?

Can I solder a single dimmer to two different mean well drivers? This fine to do anyone know? thanks!

thanks again for all the help/clarification all, appreciate it.

Excellent, so that would run the C's at approx ~70 watts then, 68v x 1.05 = watts correct? Just want to double check before I order new shit again since now I have 6 mean well's to return and 18 vero 29's already haha.

Okay, would this meanwell run 3 C's then at ~70 watts each? HLG240H-C1050B Output Current-Channel 1: 1.05 A Output Voltage-Channel 1: 238 V Output Power: 249.9 W

I would like to run the 9 C's, would like to keep it around 700-800 watts range over a 4 x 4 for the 9 cobs, preferably 3 cobs per driver as I wanted to do 3 seperate bars of 3 each, which driver would you recommend to do this? thanks again for all the help and clarification.

Okay, I am understanding more now.. thanks :) So there is no meanwell driver will allow me to run 3 C's at ~70-90 watts each? If not is the ZPE driver from cutter the way to go, PF-P400CC-C105-S-DM?

I am sorry, I am not trying to be difficult but that is showing the D running at half the power of the C's right? So of course it will be approx half the output. My lack of knowledge could be getting in the way for me understanding it lol. Going be efficacy alone its about ~5 percent (of...

missed that one.. so it looks like maybe ~8 percent difference in efficiency for the C over the D's then?

Ahh okay I see. Thank you! What do you mean visibly better? The actual photon output between the 3 is different? Or the actual color spectrum is better with the C? If it is better with the C how different are they? I will get much better results with C or over Ds? ( I actually have...

If I were to run 5 off one and 4 off the other would the one running 4 be driven harder than? Assuming it would need to be wired in parallel?

I actually was planning on 9 cobs over a 4 x 4 at ~75 watts each. That is why I ordered the 38v 80cri ones and 240 2100b driver so i could do 3 per driver. But I guess for some reason the 38 volt version is not as good at the 70 volt version.. so now not sure which driver I should/could use to...

Is there a driver that can run 3 off a single driver at ~70 watts? Would I be able to do that with an HLG-320H-C2100b? So as is I could only run 2 off a HLG-240H-C2100b at ~70 watts? The ~68volt version that is. I currently have 6 HLG-240H-C2100b that just arrived today, will return them...

Okay, if i want to run them at 75 watts, the 3k C's, which mean well driver should I use? The 240 2100b won't do 3 at 70 volts I don't think.

I ended up ordering 3500k for flower, I have a few cree 3590 fixtures in 3500k, figured I would want the same in vero's, not a good choice? I got D's also for ~38 volt version.. these all wrong? Should I return/exchange? I bought 6 hlg 240 2100b's to drive them (3 per driver).

I ordered 18 vero 29 se 3500k 80 cri cobs (~38 volt) and 6 hlg 240 2100b drivers. I plan to build 2 9 cob fixtures over 4 x 4 trays running them at 75 watts each. Anyone else run this config? I have a few 12 cob 3590 fixtures running at 1400 mah (50 watts each) and it does really well.. I am...

I am curious, anyone know what the spectrum is of vero 29 gen 7's compared to cmh? Seems cmh has the best overall spectrum, how does the vero compare? 630 watt DE CMH

That is exactly what I was thinking, like baby carpenter ant maybe. We did have some carpenter ants around last summer (pole barn).
