DIY with Quantum Boards

I think I read a few pages back Hitemwiththehine said he has one of the Nichia based fixtures. I'm assuming they are qb324s. Has anyone else here used the qb324s. I ordered 4 cuz I wanna put 2 per a/c hood and I'm trying to keep a similar footprint as a 600hps. I was just wondering how people are liking them. I don't here about them much in the threads.

thanks for the detailed explanation. i'll give it a shot after eating... if i start fiddling with it now, i'll end up starving myself for a couple hours trying to figure it out.

basically, it goes?
1. L+- hooked up to R- to create the serial connection
2. L- hooked up to -driver
3. R+- hooked up to +driver

you say i should only use the top 2 connectors, so i'm not clear on why 3 on each side is meant to be used. i'll give both a shot anyways...

should the wires that are unused be disconnected from the board?

sorry if the picture is a jumble. the wires are multicolored and confusing even for me... i should probably put a sticker on and label them.

thanks again.

I actually haven't used mine yet. The reason is that I am waiting until I get a 4x4 tent so I can use my 260 with it as well. I did, however, cobble together a 320XL from my 260 and a 90watt board. I used it in a 3x4 tent and it worked pretty good. The reason I'm not using the 324s in that tent right now is because I discovered a bunch of holes in it and so I'm just going to wait and get a better tent. My 260 is currently running my 2x4, I suppose I could switch the light to the 324 fixture, but I just didn't see the need.

I have some 324 boards also, in that thread im Pro Headies. Unfortunetly those TopDawg shits i posted pic of in that thread had a hermi at very bottom of one after i delarfed the bottoms i didnt catch, pulled the entire crop since it was just a test run for the QBs at 5th week and hashed it all knowing the TopDawgs werent keepers. Now im at 4th week under them with some Headbangers but there little since i originally started them under four 132(2700k) boards at 280w. I prefer the 324 boards over the 132's and plants seem to like the 324s more also.

I've been following this thread since pretty much day one, but life got in the way an I lost track lol. I'm hoping on getting the qbs for a 4x8 flowering tent, would four 260w v2 kits be adequate for a rich booty? Obviously assuming everything else is kept under control. I have experience with cobs, but I'm totally smitten with those sleek babies. Sorry for not having the time to dig up the answers, but I'm really really stoned lol

When I was running my 8x4, which I recently packed up, I had 2x 260w kits in one half and around 700w of Cobs in the other.
Both sides performed very well.
If I were going to set it all up again buying fresh lights then I would go 4 or maybe even 5 x 260w kits. You have the option to lower and raise each independently, unlike my giant cob fixture.. Plus I have the v1 kits and the v2 are slightly better.

Bottom line is YES!

Edit, that's not to say that 4x 260w kits wouldn't do amazing or that more is needed, but I know my temps with the wattage I was running so the 5th would just be an added bonus and have even more coverage and photons bongsmilie

Thanks, @coreywebster. The thought of shipping all those heatsinks creep me out. Will try four and expand if needed :-)

Any thoughts on qb veg/cloning lights? Got a little homebox I'm planning on using for rooting and early veg, roughly 2x2.5.

Hello everyone, as I am new to electronics, I could use some help.
I am planning on running my 288v2 QBs with active cooling. (a fan blowing onto the heat sink)
I read in the 288v2 thread that the 150w max is only for passive cooling and that active cooling increases the heatsink effeciency by a factor of 3.
Does this mean that I could run 2 QB 288v2s with an HLG-480-xxx and run them both at 240w with active cooling? If I do this, should I wire series or parallel?

I don't have direct experience with cloning with them but these would be good and come in 4000k spectrum

The absolute max per board would be 2.8A a 51.2-53.2v approximately. About 146w per board. Running them that hard is definitely not recommended as it would burn out quicker and cooling that woul be a pain.

To get 240w total you would need around 2.4A per board. That would probably take more that a fan blowing on them to cool. I would put multiple fans on each sink, and probably remote wire the driver to place it outside of the area (unless it's an open space,) as you would be running it at 85% of max power. You might want the a A or B version to dim it down if it gets too hot.

Here is a few charts on the qb288 v2

Hello everyone! First post here..
Im in the process of building my grow rooms and was looking for input on my plans for lighting..

I have 2 rooms that are each roughly 9'x5' but I have a foot of walking space around my reservoirs so its more like a 7'x3' space will a little room to stretch out.
My plan is to do 8x 3500k 304 boards spaced out evenly across a single frame above that I can lower if needed.
HLG-240H-C2100B powering every 2 panels.
Is there a more efficient way to do this or is there a way I can dim 4 drivers together? Id rather not have 4 dimmer switches for each room.

I had looked at the 480 drivers but they arent cheap..
If I get them direct can I use the 480H-C2100 on a 110 outlet if I wire panels in series? Does the driver do the step up?

No. The 150W limit is the max current rating of the diodes. It has nothing to do with how they are cooled.

I have 3 260 watt kits and 4 132 qbs in my 4x8.
I bet 4 260 kits or 4 of those new 324 kits would great.
If you have the money and want better light spread and little better efficiency you could go with 5 or 6 dialed down.

Well that's good to hear about. I was starting to rethink my purchase since the Qb324's kinda seem like the "red-headed step child" of the qb's. Nobody disses on them but nobody wants em in their house. I can hardly wait to get em wired n pumping out some photons. The few people that do have em on the forums seem to like em though. Good luck on your next run with them.
