    No problem. I run 4 cobs per 200w driver. I use meanwell hlg-185h-c1400b drivers and my friend is using hlg320h-c2100b. I'm not familiar with that driver or luminus cobs. You should go to the led lights page and get some advice before you buy.

    with those Luminus chips you get the best bang for your buck

    Stick with the hps, you will end up spending a fortune and you won't get better results.

    how are your results with eight 50W COBS ?

    I have been extremely happy with my cobs. I'm using 16 50 watt cobs over a 4x6. I don't keep track of total weight for the entire harvest, so I can't tell you any numbers. My buds are bigger and the total weight is more than when I grew with 2 600 watt hps over the same area. I save 400 watts and everything else is better. I like mostly that it is framed to cover the grow area perfectly. They are bright as fuck and don't get very hot. The only negative is the up front costs.

    I don't know a lot about quantum boards yet, but look at those too. They may fit your situation better. Either way, cobs or qb are the way to go.

    I know that you may be hesitant to switch. You can loose a lot of money and harvest weight listening to a lot of these light sellers. I did. I have over $10,000 of trash leds that I expected to replace hps with. Most of them did ok, just directly under the light only. Then, after a few months of being driven too hot, some of the diodes burn out. Then some of the cheap ass drivers broke in mid flower. Then I saw greengeenes results and got an apache tech at600. I love that light. It definitely replaces a 100w hps, but is heavy and cost $2,500. Now that I know how easy it is to build a custom light that is more efficient than hps, the only question becomes which one.

    Yeah, I have looked at quantum boards. I like the idea of different light sources spaced out. I was thinking of running 8 COBS in a 4x4, that at 600 is damn pricey

    You will get good results with 400watts of cobs in a 4x4. Better than a 600watt hps. I made the exact change but under a 3x3.

    Look at citizen clu048. cobkits has some for $10. $5 more for the newer models. You may be able to find some cheaper. I would get 36v cobs and two meanwell hlg184h c1400b or one 320h c1400b for $100. That's $340 plus less than $50 for the cob holders, frame, and wires. $400 for a 400 watt cob is pretty good. You can always add another 4 cobs if you decide that you want to yield more.

    The cobs are spaced out pretty well too. I make mine so that I can move the cobs if I need to. Its helpful to put them directly over the center of a plant.

    Nice to hear that 400W of cobs will be better than a 600W hps, cant wait to get some LED's. Might try my luck with 400W for now, and think about adding more cobs in the future

    3x3 is a bit small for a 600w hps, that could be why you seen similar results, 600w hps is really made for a 4x4, 1000w hps for 5x5, 400w hps for 3x3.

    I bet a 315cmh would give best results in that 3x3, 1-2 lbs per harvest ez.

    That's how i felt before i bought my first LEDs, then i got them and used them for several years, honestly they are really over hyped by people who couldn't manage their heat properly with HID lighting or people trying to sell you products. LEDs are mainly for micro grows.

    Curious to see what kind of light setup you would go with for a 4'x4'

    630 CMH

    Could get 2 pounds per run with one of those in a 4x4 with proper training plus it has UV light and far red, unlike LEDs which have not a great spectrum for growing plants. UV is a huge factor in resin production meaning CMH grow buds will outshine LED grown buds.

    Not too sure how a guy could get that into a 4x4

    QB’s or 2x315 cmh... I would assume 500w of QB would pull similar PPFD to 2 315’s with better penetration because you can hang em lower and still get great coverage. This is however, an assumption because I haven’t used cmh yet. Though I plan to run some comparisons, and I’ve seen the goods with both from friends. Watt for watt, LM516C QB’s are crushing.

    when comparing LED’s to HID, you have to factor in the cooling requirements of HID. Watt for watt, the QB wins every time.
