What would be the efficiency of cxb3590 3000k cb bin 36v running at 1.05 amps, there is no accurate info anywhere in the forum so I guesstimate 55%, is this a good guess. I wish I bought the 3500k cd bin it has 64% efficiency at 1.05 amps should have known the efficiency difference before I ordered them, stupid me.
Ordered mine from Jerry too very helpful and good service.

Mr Supra and all the fine people here, what's up! I'm new here. Supra I like your designs, the work looks neat and clean with no fuss
.
I'm completely new to this and haven't done a build yet, but I've been reading a little, looking at peoples work, trying to get the concepts. I hope someone can help me answer some questions or perhaps point me in a helpful direction...

For my first build project I'm imagining a passively cooled light bar built on one massive heatsink bar stock. Maybe it could have fans, if need be. I would like the option to safely crank the chips to 70%+, but daily driving around 30% - 50%. I'd be saving money up front buying fewer chips, but able to push the limits of the chips, despite what I hope is nominal loss of efficiency. I imagine one benefit would be high photon density in a small footprint. I just want to keep it in bounds so I don't burn anything. I'm not sure where the sweet spot is, or if I'm even on the right track. maybe my first build should be more conservative. Anyway I have few technical questions that I hope are not too clueless.

I see that the HLG-185 driver has the high voltages for the 3590, and I assume this is more efficient, so that's good reason for choosing the HLG-185?

Let's say I go that route. If I want to safely crank up the 3590's to >65% (max 85W per chip) at high voltage, am I good pairing two 3590's with one HLG-185?

Would >65% power burn the chips and/or driver if passively cooled? Would I need forced air? Yeah probably. How much efficiency does the chip and driver give up, respectively, when you start to push up past 50% like that, as long as I can keep the temps reasonable?

I gotta say, I'm pretty lost. But I'm new to this. There's a lot to digest. Do I wire the chips in series, constant current? How do I match the chips and driver with the appropriate dimming hardware?

On a different tangent:
Would a 600W HLG-600H36 safely drive six 3070's at 36V >80% (550W)? That's really pushing it? I don't want anything to catch fire.
Would a single 600W HLG-600H safely drive six 3590's at 36volts >70% (550W)? I guess it would be more efficient than the 3070's for the same or more brightness?
Would I be needing forced air for the chips and/or driver, or could I get away with massive passive cooling? Again, clueless as to how exactly to wire such a setup, in series at constant current? Dimming?

Am I even in the right ballpark here? I really have no idea. I need a guidebook. I've read the driver and chip data sheets and some white papers on component matching, but I'm not an electrician and I haven't studied the math, which is frankly over my head. But I like to read, so, any suggestions are welcome. I'd like to figure this shit out.

Thanks!

Well at least you know how to ask a simple question that someone can answer!

replacing your veg lights can be relatively cheap. drive under nominal, and use minimal mostly passive heatsinks with the smaller cobs and a temp of 5K or higher. BUT you will get more bang replacing your HPS with cobs.

yeah, i am going to build a veg light soon, eventually a flower light also. I got a lot of work to do as far as carpentry to do first though, that is going to drain all my "extra" cash.

holy shit, I am going to stay tuned to that!

The plan is to do your 4 x CXB3590 @56.3% efficiency with the 200W Meanwell driver... Times twenty five. I'll use 24 in the array and keep the last for a spare in case one craps out. Yes, I have plans for the heat generated. Each one will cover 6 ft², so should be right at 824 PPfD.

It's going to take me a minute, but I pretty much have everything planned out;
1. 30A@240V circuit and lighting control box w/trigger cord
2. Four 240V power strips to plug drivers into, about 1200W ea
3. Four COBs and a driver on each module, interchangeable with the rest with a hanging clip and a plug

After that it's easy street; just follow directions for the 53% efficient setup with CXB3590 COB chips.

Sounds very sanitary. Did I read right, that each four-COB module will cover a 6'x6' area, or is the 24-COB array that covers 6'x6'?

OK so I think I got it.
I gather this:

four CXB3590 3500K CD mate well with one HLG-185H-C700 at 72v effectively 92W-200W/ 64%-56% efficiency:

min power:
92W (23W per cob) = 64% cob efficiency

max power:
200W (50W per cob) = 56% efficiency

And this 4 cob array would yield about 99.3 PAR W into the canopy.

Is 99 PAR enough to flower a 2x3?

If I wanted to bump up to 5 cobs at 72V 240W it looks like I could use the HLG-240H-C700 and get the same efficiency.

For lower up front cost (at the expense of efficiency) I could use four to five CXB3070 at 36V with the appropriate driver, the HLG-185H-C1400 or HLG-240H-C1400, respectively.

If it works the modules could scale into larger arrays as needed.

I think this is my first build.

I'm pretty pleased with myself, i think I'm starting to grok the math, a little.

I'm got all my figures from earlier Supra posts (thank you!)

I paraphrase:
4EA CXB3590 3500K CD bin 49W
56.3% efficient = 196 dissipation.
W = 110 PAR.
W *.9 losses = 99.3 PAR W into the canopy and 85.7W of heat into the heatsink.
In a 2X2 = 24.8 PAR W/ft² or 1235 PPFD averaged (very high intensity maybe too high
unless dimmed).
In a 2X3 = 16.6 PAR W/ft² or 823 PPFD averaged (high intensity, excellent buds)

And this array would yield about 110 PAR watts. I'm just cutting and pasting from what others have claimed, does it seem to hold water?

Is that enough to flower a 2x3?

That's pretty much what I'm building a module with, yes. I didn't come up with this combo, it just seems to be the one that fits my needs best.

Bonjour
How much for the hlg-240-700?
And where is it available?
Thanks
Have a great day ★

Greetings! I don't know about prices or vendors, because I haven't bought or built anything yet! :lol:
I have seen helpful suggestions before, on the forums, but I've lost the thread. One thing I remember is that if you are in North America you might avoid the shipping charges from Chinese vendors, as the Drivers can be heavy.

Cool! I'll stay tuned to hear how it works. I got the idea for the combo from reading Supra's very informative posts. I plan to start my own build in a few months, mainly due to cost.
