THIS. I just wanted you to know this is the post right here that launched a thousand chips! ...ok, 100, but I couldn't pass up the Hellenic pun, lol
We're going to have something interesting for show n tell by this Xmas, that's for sure!
You're a baaaaaad influence- without you, I might have remained blissfully happy with my 860W CDM lamps for years...

hi guys, I'm from Spain and is the first time I write in the forum. I'm really impressed with the quality of the content of RIU, and especially this post Supra, the best I've found for my DIY Led Cob.
I have some questions, settings a
@ 49.7%
(2) CXB3590 CD 3500K 72V @ 1.05A (75.5W ea)
(1) HLG-185H-C1400 (running at ~ 1050mA)
I would allow dimming up to
@ 45.7%
(2) CXB3590 CD 3500K 72V @ 1.25A (91.65W ea)
(1) HLG-185H-C1400 (running at ~ 1250mA)
or dimming down to
@ 64%
(2) CXB3590 CD 72V @ 350mA 3500K (23W ea)
(1) HLG-185H-C1400 (running at ~ 350mA)
I'm right? Would it be safe to reach 1.25A? If so, it would be by far the best option for me. How should it be done to dimming?
thank you very much for your time and congratulations for your work in the forum.

Hello, thank you for the compliments. Your plan makes good sense. I cannot guarantee you will get the full 1.2A, that will depend on the driver and the COBs which will vary slightly. Recently I tested a batch of these
2X CXA3590 72V on HLG-185H-C1050A. The drivers put out 1.13A at maximum (90W/COB in this case). It may slightly reduce driver efficiency using them this way, but you may get more current than the HLG-185H-C1400, hard to say without testing. I will have an HLG-185H-C1400 to test soon.

so how many cobs do you have with lenses Supra?? i'm about to put in another order and fill up this heatsink and was thinking of getting some, but was thinking about what you said with the "loss" that a lens will produce and wether it outweighed that with penetration.
right now my 10x36 HS has eight CXB3590 on one HLG-185-c700 and i will be doubling it up with eight more CXB and another one of those drivers.
Also i was thinking of getting some in a different spectrum but have not seen too many people throw different specs on the same unit, what's your take on that?

If you are running them at 50W ea I highly recommend a lens. If yo are running at 23W each it is a toss up between lens, reflector or bare if they are in the center canopy.
If you use a variety of spectra they will mix to some extent. I see nothing wrong with that plan, maybe even beneficial. As always I believe efficiency trumps spectrum in this case but as long as you are getting the top bin for each tint I'd say go for it. (3000K CB, 3500K CD, 4000K CD)

So if I'm reading this correctly, if I'm running the CXB3590 chips at 50W to get the 56% efficiency, you strongly recommend using lenses.
I'm planning about a three foot distance between trellis and COB. That means a minimum bud to cob distance of about one foot, as some buds could stick out that far. Generally the canopy is about 15" off the trellis.
The light array will be 6' tall x 12' long. Is using a lens better than no lens and if so, which one would you recommend?

yeah so do you think a lens is better than a reflector. i guess with a reflector you don't obstruct your light in any way... just trying to see the pros and cons of both.. and i'm probably just going to run them at 23W each...but ya know how plans change

Thanks for the answer, the HLG-185H-C1400b should not give 1400mA? Why not come to 1200mA? For HLG-185H-C1400B is ok the 143V? or that´s why is better HLG-185H-C1050A?
I'm already talking to Jerry and everything goes great, giving me incredible prices as well as facilitating a change of amount on the invoice to save taxes. he said me DHL, but ChinaPost is safer and cheaper, right?
Now I start to look like building a dimming, I hope it's not too difficult.
Thank you

The best advice I could give would be to try bare, lenses and reflectors and see what gives you the best uniformity and intensity. Realstyles reported a nice boost at 12" distance with 25W COBs by using lenses, inside a tent and I believe he runs his canopy at about 12". I have a lamp that runs the COBs at 80W ea and the distance to get an even spread is about 18"
I have been using both lenses and reflectors on the COBs that are bordering a walkways and running them bare when they are in the center of the canopy. I have been using both PAR meter and eyeballing to try and get the canopy covered as evenly as possible and trying to reduce waste and wall reflection.

I would like to know the answer to this question also. Spectrum King's Cree TEMPO test measured the lens loss to be 6%. If that is true for our lenses as well I suspect lenses will outperform reflectors. On the other hand I have quite a lot of COBs and I like using free DIY reflectors that can be cut to a custom shape, short, tall, oval or both tall and short on one reflector.yeah so do you think a lens is better than a reflector. i guess with a reflector you don't obstruct your light in any way... just trying to see the pros and cons of both.. and i'm probably just going to run them at 23W each...but ya know how plans change

The HLG-185H-C1400 may be able to go up to 144V and still put out max current, but if the COBs voltage is higher than that the driver will reduce the current as necessary to limit the circuit to 143-144V. As the COBs warms up Vf falls and the driver will increase the output. At 1050mA Tj 60C the CXB3590 is about 72Vf but it will vary from COB to COB. So in practice we wont know how much current it can put out until we test it and it will be different for everyone.
Now that I have seen enough HLG-185H-C1050A that put out 1130-1150 mA I would recommend that over the HLG-185H-C1400 for those who are looking for the highest output. But I would recommend the 1400 for those looking for the highest driver efficiency.

I'll be running CXB3590 chips at 50W, about 18-21" from the canopy tops and 36" from the trellis, or the back of the plant, so that's my canopy depth.
My first pull it out of my ass guesstimate seemed to lean towards 80° lenses. Let me know if this seems right to you based on the stated dimensions and specs above, or if you'd start with something else?

then HLG-120H-C1050 would be the most efficient option above HLG-185H-C1050. so can use almost 100x100 driver and can modify it 7.5W to 75W ???? Thank you very much for answering my (stupid) questions as quickly and didactic way !!!!!!!

If the driver HLG-185H-C1050C puts 1150 +- are you sure fits well with 5 CXB3590 36v cause its seems to be 207w or so... If that works seems like awesome combo efficiency/Cost.

HLG-240H-C2100B could be a good option for 3 x 36v too
