    Yes it will work. You will need to run 2 boards in series and the other 2 boards in series. Then run those 2 "strings" in parallel. The boards will be running at around 125-130 watts each.
    Hey Stephen, I understand you are one of th epioneers for QB lighting. I recently purchased 2x 260w qb light kits from HLG. My question is will they work on a single 15 amp rated outlet? The since ill have 2 of the drivers, what is the max amount of boards I can use? Ive been reading 3. Also I purchased both kits in 3000k spectrum. Will this order be ok the veg/bloom in a 5x5 tent?
    Hello Stephen, I've read about your calculations for the ppfd per square ft. for the Cxb3590.
    Can you please please tell me how to calculate? The goal is to know how much ppfd I'll got in a specific hight.
    I'll run 10 x Cxb3590 72V 3500 80 with 350, 525, 700W

    Thank you so much.

    I'll need to know the area you are running it in.

    it is 0,84qm...for that area the ppfd/m/s is 1500....
    i want to know how much the plant gets in 10cm distance and 0,084qm for example.
    Ttystikk said i should contact you regarding getting a quality cob led grow light on a budget need at least 200 watts I have a 3.5ftx5ft space my budget is $200 us

    You need a minimum of 400+ watts for that space. With a budget of 200 your best bet is a 1000 HPS from Craigslist honestly. Check out cobkits. He may have some really hard driven engines that will get you started. Honestly though 16.5 sq ft is a big space to light up and a $200 budget is r small for the amount of light you need.

    Hey buddy. Another guy from the 315 thread looking for recommendations. I want to upgrade at least a small room from 600 hps/315 cmh to cob led set up. Not overly into diy. Can you recommend a couple "replacements"?

    The CX-6 will be a good replacement for 315 LEC.
    Hey Stephen, just an update...

    The light is doing so much better than the P600 so I pulled it and put it in as a vegging lamp. the difference in the buds are very visual, not taller but much fatter with much more mass. I'll post some pics to my thread.

    Hope your business venture is going well and brings you much prosperity.
