      Hi Supra.. Need you advice..
      I have One CXA3070 working at 50W
      I use it currently on top of 1 week Seedlings.
      What is the distance i should put it?
      I soon will order a driver and run 6 CXA3070 together..
      And when i do get all 6 workig, what distance should i put between the panel and my veg plants?

      Hey supra heard a lot of great things. I have a question. I just recently purchased 8- cxb3590 3500k 36v DB cobs, 8-150*70mm pre-drilled pin heatsinks, 2- MW HLG-185H-C1400B drivers. For a 4x4 area what would proper displacement and spacing be?

      Dear Bro
      ive got a brain bubble while reading info and find U as a very good example
      my english is no good
      i order 10 pcs prolight opto PACF-57FVL-BC8P ( 6 at 3000k & 4 at 5000)
      what you think bout this mixture
      and a problem! which driver works good at this optos?
      ive found a meanwell Mean Well HLG-185H-36B /5.2 a
      i calculate something like f 10 cobs at 520 ma and ive got around 30000lm at 187 w/im right?

      Hi Supra,

      I'm looking at this Mean well HLG-600H-36A. On that doc it says I can run 6 vero 29's on that power supply running at 2.78 amps. It looks like these are adjustable? if so do you use meters to tell what the amperage is?

      Also since this is a 600 watt power supply does that mean that each of these 6 chips are running at 100 watts each, would I still need active heatsinks with this setup?

      I'm currently gathering information on my light choice for a 4x12 table, I've watched videos from growmou5 and saw where he's reccomended you as the guy in the know. Is there a way you could pm me where we could discuss my options as my electric situation is unique

      Hey supra, quick question. Should i use the kingbrite 120┬░lens or no lens. I see growmou5 uses lens but ive read some post saying the lens penalize the cobs and some that say they help. I need your help. Thanks

        The kb120 just spreads the light better, Not so hot in the middle and more light away from the centre. I was thinking of using these lenses if i decide to go scrog. It does drive up your startup cost though.

      You rock! thanks for all the info on DIY LEDs. Do you know anyone other than Jerry where I could buy COBs from a high bin? The best bin he has for the 3590 is CD, and he doesn't have any CXB1820. I am having a hard time finding any COBs from one of the top 2 or 3 bins. My goal is 45k lumens while staying under 300W. I like the idea of the 1820 because I can get a good variety of 2700k,3500k, and 5000k

      Hey supraspl. Thanks for all your posts and help. Can you give me your opinion on if you think the cxb 3590 3500k top bin is worth the price increase over the cxa 3070 3500k top bin? $53 vs $22.5. Thanks i ask because you have that experience with both and i trust your advice. Thanks

      Hi , Supra I'm running a lpc-60-1400 on a cxb3590 36v in a space bucket setup (http://www.spacebuckets.com) and would like to know how far away do you recommend from the cob , I have two 5 gallon buckets stacked now. .

      Hi supra. Would you drop by bin comparison 2 thread? Seems like something off with the numbers to me. Colder spectrum consistently higher ppfd/w when colder light should hace fewer, but more energetic, photons per watt. Im a noob so not too sure. Check?

      I'm in a small cabinet so I have the COB's on a 28" x 5" heatsink with the fans and fins outside of the box. Most of the heat radiating bits are outside. Cab temp is +5F over ambient and I think I'm generating about 950micromols. Any thoughts on this setup? Thoughts on optimizing for thermal over electrical efficiency? Appreciate your continued contribution to the community. Best, j

      Sup - I recently built a five COB light, all CXB3590, three 3000K and two 5000K. I'm running them on HLG-240H-36 for the 3000K's and a HLG150H-36 for the 5000K's, in parallel. I noted that most are using a single driver per COB, is there an advantage to doing so? I'm optimizing for maximum photon output while not pushing the COB too extinction.

      Hi Supra,
      Appreciating the science that your bringing to the community !
      I was wondering if you advocate the use of lenses ? I've been through the forums and there seems to be some conjecture ?!
      Thanks in advance

      I found this in a comment of you.
      Cree CXB3590 3500K 80CRi CD bin $43 ea @1.4A (50W) 56% efficient typical - cost $1.56/PAR W
      Cree CXB3590 3500K 80CRi CD bin $43 ea @.7A (23W) 64% efficient typical - cost $2.93/PAR W
      could please also post about the 1050 driver?
