Yes 4 boards will cover a 5X5. If you get type A HLG 240 and the slate 2 heatsinks you can crank them up to 300 watts each driver. 2 HLG 240 will and 4 boards will do the job in this way.

How can a HLG-240 be cranked up to 300w each? I thought that if you run them open circuit it maxed out at around 256w... (HLG-240H-C)

What's the price breakdown for these boards? The cost for the diodes alone is only about $8.50, does board manufacturing really cost that much or is it more a matter of economies of scale? I've found another supplier - aceled - that is willing to do a similar board using S6 diodes. I need to do a run of 50, but the overall cost will be $54 per board wholesale. Where are you guys getting $21 of extra costs while using lower bin diodes?

Edit: Genuinely curious, not throwin shade over here.

Exactly why I said I would pay around 50 for them, not worth 75. You have a link to the supplier? PM me if you can, I would rather make my own lol

People providing good products and services are worthy of a return on investment, research, education and time. Seems with quantum boards and lighting handled by Robin and Steven sell quite well at set prices. Often they are out of stock. This would indicate at very strong competitive product line but the business may need to add sourcing resources.

This also applies to herbal products.

its silly really,@75 bucks for the board,lets say 20 on the heatsink and 60 on the driver so 155 call it 160,00 and you pull just 1 measly oz from under it worth 250.00 in most places easy.you saved about 50 bucks after electric costs if you fucked up and only pull an oz off the plant lol. im finding the DIY community in general is the most cheap bastards you would ever meet lol.

Cheap is good. Means they are always on the hunt for good deals which, in my opinion, is the fun part.

Keep in mind that not everything is good or the best for everyone. Everything has its place. These quantum boards are great for side lighting and providing a fairly even distribution of light. Working in conjunction with other sources may provide much better results than the sum of the individual sources, kind of like the Emerson effect.

Nothing says you can't mix it up and have to go with only 1 product.

  • HLG-120H-C1400 with 2 or 3 or 4 boards for 150 Watts

    i have this driver so i know this combo will work. so if is better to use that one and save the 1750 for cobs i will. just looked over the specs on board and if i did series its to much current. 150ma over correct? but if my math is correct paralell would not be to great either on this particular driver. That would make each board running at like 600ma?

If it were me with the components you listed, I would keep the higher wattage 1750 for the cobs and use the 1400 for the QBs.

With CoBs you are more likely to run higher current, or at the very least have the ability to do so. Lots of light in a compact area.

With the QBs, the strong points are efficiency and the even light distribution so higher current isn't as important.

2 Qbs in parallel off the C1400 looks to be the best way to go in that case. If you want to cover more area, you can run 3, 4 or more in parallel.

Word awesome ty. ill prob do 3. Have two identical closet and have 4 cxb 3590 on a 1750b in one and wannt do a test on these boards for a comparison. wanted to try to use the 1750 to make a better comparison. But will still work considering the space and i will just dim the cobs to 1400. Appreciate the help

we shall see if these are just good for side lighting,im betting they are better than that.oh and mix it up is my middle name lol
sneak peek,4 x qb and 5 x cree cxb3590,should be around 770w when im done or if i ever find time to fuck with this :eyesmoke:
On paper it should be better than a gavita :hump:
