OMG..look at the size of that room. I'd run a few steel beams overhead and superglue some 3590 on the ceiling

cue the "eye of sauron" photoshopped over some plants!one light to rule them all
one light to find them
one light to bring them all
with 12 hours darkness, stone them
I know the Mean Well drivers can be dimmed with resistance, 1-10 analog volts, or 1-10v pwm. It should act the same no matter what way you do it with the built in 3-in-1 dimmer function. It works be telling the driver to reduce output current.
Do you mean instead of reducing the current to lets say 700mA from 1400mA with a 100k Ω pot, which give a steady current of 700mA. It dims by cutting the current on/off so that its still 1400mA but flickering really fast. That sounds like what your headlamp is doing, kinda like a shitty refresh rate. I have seen fan speed and 3mm leds controlled like that, Im pretty sure that's not how these drivers work.
The problem I have run into is that the arduino PWM voltage is only 0-5v and I have to build a circuit that will multiply the voltage to make it 0-10v. All of this at the moment its way over my head, more testing is required but I am determined to figure it out and to paraphrase/misquote JFK.
We choose to do these things not because they are easy, but because they are hard and we have nothing else to do.
You are correct, everything is hidden inside.Looking good WN very clean, where are the drivers and fan PSU, hiding inside the boards?
Any update?Here we go then.
Plants were light deprived for 3+ days while I setup the COBs. The sativas were on the outskirts of the 560-watt Chinese panel for weeks too. They're all starting to recover already, and it's only their second 18-hour under the 3070's. Also I plan to get Orca film all along that back wall soon.
I'd love to see what you went with for drivers and PSU, and how you laid those out in the rail!You are correct, everything is hidden inside.
Great light. You and I are thinking a like. Getting everything tidy and clean in those "housing rail" is exactly what I am trying to do. I was going to do some sheet metal work, but why re-invent the wheel when they can come out so clean like yours.View attachment 3202451 Time to flower...
I'll start a thread soon. Those plants got huge and now I want to put my own hybrid into bloom for the first time. So I have to hang the Chinese LED back up, and maybe sacrifice one or two of the big plants. I'm trying to avoid that, but can't really think of a solution. It's too hot in my garage to put a tent, forget it.Any update?
Such a sweet set up!
Got a journal going or something? Would like to fallow!
Drivers are approximately 1amp for each cob and a single 12vdc for all the fans. No special layout just placed everything inside, it fit perfectly.I'd love to see what you went with for drivers and PSU, and how you laid those out in the rail!
Thank you. I would like to see a sheet metal one if you build it.Great light. You and I are thinking a like. Getting everything tidy and clean in those "housing rail" is exactly what I am trying to do.

I see your point, if for some reason your design required a single light source that might be a good way to go (CXA3590 running hard). But if you are able to spend that $$ on running at a lower current, you can achieve even high levels of light output for the less $. If for some reason maximum efficiency was the design goal, you could run the CXA3070 AB at 300mA and get up to 56% efficiency. That would cost $9.09/PAR Watt for the emitters, but the driver and heatsink cost would be much lower and of course the electric bill also.oh yeah no doubt the price blows, but i was just thinking for maximum performance out of your COB's if you had some money to throw at it. would it be viable considering the radiator is in the room
