email me and we can talk specifics. i havent put them up yet but i have 320h-48A drivers as well
Will do, looking to get started again in April. Two HLG-320H-48A would push 820 watts, correct? I don't want to bust out the datasheets if I don't have to.

Is there a thread about the new generation citizens? Where the information isn't buried in 70+ pages lol.
not much to report

same sizes
same nominal voltage
few % flux increase
slight Tj-c improvement
higher allowable Tj and Tc

overall about 3% relative bump per datasheet

Need an opinion on veg light Kevin's and chip.

Want the 1212...but

4000k?
5000k?

for veg i just put together a 4000k80cri and 5700k80cri 1212 light.
Thanks Cobby everything came in looking great and i could finally retire my last blurple light!
Oh right. Yeah I've been running Cree xte royal blues and xpl 6000k monos in mine for a bit over a year. Something isn't right. Was getting weird growth and what lookz like a phosphorus lock out when the temps get too cold. So have been changing humidity and fan counts and intake air and anything I could think of. Anywayz...veging a couple of seedlings under my Citizen COB build (3500k) and the results are completely different. Awesome green growth, quicker sexing, just a more mature stronger plant....really weird and unexpected that a combo of colourz would do this to plant.. (shrug?)

So I like the 4000k 80 CRI idea...thanks :)

You will need a multimeter cause u messed with the voltage adjustment but the lo adj is what you wanna use to dim them the lights. Lo adj affect amps
What watt driver you have?Max forward voltage for the cxm-22 is 55v but lets say 54v. If you are using hlg-185-48 then the max voltage on the driver is 53v. So you should be ok. But per the cxm-22 it has a 50v min so i wouldn't go lower then that.

I'm using a HLG-120H-48A driver. No multimeter here (and not planning on buying one), I'm just not into DIY. In laymans terms, where should I have the adjusters if I want the light running at around 75% power? Should both adjusters be kept in around the same position?

buy a $5 multimeter you'll be glad you did.

otherwise a watts up is useful to measure wall power

turn Vo all the way clockwise and adjust with Io
Thank you, that answers my question :) I have been meaning to buy a wall power meter, will grab soon.

i already shipped your order (which was placed 3 days ago). If you wish to return it please follow instructions on the site.

Also if the extra parts in there are confusing, the 2-slot wagos you spec'd didnt make sense to me on how you could make it work so i threw in some 3-slots as well

for the record silver_or_lead's order took 11 days to ship and i ate $35 in shipping and also threw in extras. Yes the last 2 weeks were a mess but im pretty sure i did everybody right (and if i didnt please let me know). i want to be known for the usual fast service not for this atypical period where the world was kicking my ass

i still need to go thru pp and process refunds which should be soon. after today i am 100% caught up on all non-customs including those up thru yesterday
