Had to put A or B choice to a very OCD person lol. Time to do a google for the driver and find out the difference between A or B =0p

Big improvement? no ...... small improvement? maybe...... untested ? yes
Beating 2.1ppf/w(nextlight mega) is not an easy feat, it's not just about the chips, it's also about building/designing a system around them.......having unlimited access to a sphere helps this process
"quantum" board is basically a DIY part atm........is just sticking it to a flat metal sheet an adequate cooling method? who the fuck knows
rows of mid power diodes so close to each other+ secondary pmma lens+ no heat escape from the boards(look at the nexlight how it has slits above the mcpcb) and I doubt it would even get close to 2ppf/w
prove me wrong HLG
so you can tell system efficiency from eyesight?.....................interesting
I have some 6500k 18w led floodlights that I swear are as bright as a 250w MH, I'll sell them to you for cheap

"162.2 Lm/w System level
PPF/Watt 2.45"
Not easy to beat 2.1ppf/w. But pretty sure HLG did have the QB checked in a sphere before making the claim.

Read that post again, Samsung online tool/calculator used for that #................no sphere results

These where designed with a company much bigger than any lighting company in the Horticulture industry hands down. We worked with a fortune 500 company (top 125) whose sales exceed 30 billion annually. So to say these are not designed with a minimum of 5 led lighting professional engineers would be a flat out understatement. We had an agreement that went south with a sister company to this really big company. (Manufacturing Arm). Our reps where just as surpassed as we where when they just stopped the project without a obscenely huge order of just bare boards. We then moved forward with the board production on our own using big companies supplied parts (all they wanted from us anyways) . We do have a housing for our design that's really close to production ready. Honestly we just wanted to give people on the boards that got us started a chance at these to play around with and save money until we where ready to sell complete fixtures. We designed these units to not only produce high efficiency light (over 2.4 umol/w) system level but also do it with the industries first light that actually has a center cool spot.....
If you look at the boards you can see the optics reference lines. We put as many diodes in each row as possible not to necessarily create the highest intensity possible but to create the most efficient light possible per watt using the optics we have chosen. I can tell you that the 561C has a 20% higher efficacy than 561B. I can also tell you that there are different PCB boards that range in cost as well. All metal core isn't created equal.
As far as heat is concerned we have lots of diodes close together but what really needs to be looked at is heat watts per sq inch of board. As I've said above running these at the intended 80 watts each 4 run 55C on that 24"X24" aluminum plate with no air movement. Introduce a small fan and they are at 30C-35C. These are peak temperature measurements on the face of the LES surface. The board itself is 1-2C cooler.
The most amazing thing about these boards aren't the diodes but the optics. Once people see what we designed and why and how even the converge is edge to edge on the canopy without the use of reflective material they will understand why it took us almost a year to come this far. I've personally spent 100s of hours on this design as has @robincnn .
We will be getting sphere results from a completed prototype unit soon as well as light distribution. Building a board and sticking it to a metal plate is easy. Building an ip65 unit with proper optics is a different story all together isn't it
Also we built these around CC drivers which in my experience is not what 99% of board designers do. We studied long and hard to get these where we could offer multiple wattage/sizes and use Meanwell CC drivers. We had tons of driver options but we stuck true to meanwell and made it work.
Thanks for being subjective it helps keep people from resting on thier laurels as they say.
Also @robincnn will have anodized hear sinks for these boards in the coming weeks.

Are the optics of any use if you plan to scrog and run these as close as possible to the canopy and have close reflective walls?

If running close with reflective walls I would just go bare boards.

Fair enough...............thanks for the internal info, didn't have to do that
Don't like people calling Nick's fixtures "next mistake", POS, etc.........when in fact they are efficient and some of the best ul/etl listed panels on the market
good luck on your ip65 unit

@robincnn What would you recommend for a 3x3 tent in flower? I'm doing a new pheno run in there in about 35 days and the light I'm running currently is pretty damn shabby. I'd love to upgrade to something like this. I was thinking 6 of these boards run somewhere in the 50-75 watt range with a couple HLG-240's?
I'm pretty happy with my current citi 1825's at 80w each over my 8x8, but I'm really intrigued with this new mid power tech. I've been reading data sheets all morning and I'm hyped.

I wonder if these Quantum Boards would be great to use as side lighting panels -like make the QBs be the walls of the grow space -as well as the overhead lighting, too.....almost kinda like that Sun Cloak thing -except more!
Can't you just imagine a grow "cubicle" set up with an arduino so that the entire East wall lights up first, then the other overhead and wall lights come on and then at the end of the day, everything slowly fades to black? I'll bet that could make for some very interesting results! Well, that's just a dream beyond my means, anyway.... I'd like to try out a Quantum Board though, for sure! I think I'll just sit back for awhile longer, though, and observe how they perform and what the best way to use them will end up being.
I really like the thin profile and relative ease to put them together -almost "plug-n-play"!

which color/cri are you running? with what heatsinks?
