Quantum Board Numbers.

Are there any official good quality meter readings for the Quantum boards yet?

I've been trawling through the site for a while and although I see some on page one of the main thread, I cant find anything solid.

I really like these boards, but my grow room is a little larger than a 4x4 foot tent and so far I'm really struggling to see anything more than a 4 board grow with a few plants (absolutely no disrespect intended), and even then the details can be very grey.

I understand the QB's are in their early stages, but there must have been a few fully finished grows with more than a few plants surely?


To invest in this equipment people will need facts, numbers, and to some extent assurance. I understand that a 2 board grow is an easy thing to gamble with. But what about those of us that might need to replace 1000w lamps or cover 10 x 8 feet areas?

Why would I fill my room with Quantum Boards over CMH or 1000w DE?

I am in no way being negative, if I though the tech was in any way not right I wouldn't be here typing. I have maximum respect for the chaps at HLG / NGL, and I believe in the technology, been a fan since the go with LED's.

If anyone has some serious stuff to show me with these Quantum Boards please please do link me up with some grows, buds, numbers.

Many thanks and happy growing. :peace:

  • Estimated LER 321.60 lm/W
  • Estimated QER 4.86 µmol/J
should tell you everything...

I had seen these. And I say this with all due respect for HLG, but Estimated leaves a lot of open ground.

I cant take an estimated number, from a single (unknown to myself source) and then use this to make a well judged decision on making a $3000 investment.

@ G.V from what I'm seeing and again this is a guess, but if you put 6 x Quantums per 4ftx4ft area and ran them a little soft say 300-400watts, (will depend how high you hang them and if you have lenses on) you will have more than ample light, overlap to next group of panels and plenty of scope to run them harder if you desire. Each group will leave you in the 1000watt se realms or more if ran hard.

I'm sure if you email Robin with your exact requirements he will soon sort you out.

I was under the impression 4 boards will work a 4x4 area?

Again I'm not in any position to say for sure as I know very little. I get most of my knowledge from the HLG site.

I have contacted Robin just to ask about the drivers though.

@G.V 4 will yes but again depends how close your going to run them to the canopy. You can always start at say 4x4 and build from there.

I need 20 Boards to run my room.

To be truthfully blunt, if I add any more boards the consumption would go through the roof.

Again I say this with honest intent, but what good is using more watts than HPS?

I understand the umol / Par might be double from the QB's than HPS or even CMH. But until someone shows me double the yield or buds the size of oak tree trunks I will stick with lower consumption as my key interest in these.

I'm honestly not here to rain on any parades, just to get as much info to make a wise decision. As I said I really like these boards and would love to have them lighting my next grow.

But on the other hand I'm a very cautious fellow. :bigjoint:

@zypheruk tbh bud, I dont want to put any pressure on you, but your grow is kind of the decision point. I'm waiting to see how you do on yours. So far it looks sweet as, and I would have no problem getting what your getting out of every 4 boards I use as my wattage will be about 25% less.

Just wanna see the finished result.

There are many successful Nextlight grows documented here. The QB's are similar except they use a newer, more efficient diode.

@G.V lol don't base anything on my first grow with them, it was a learning curve and I no I can do a lot better. I'm looking at the critical+2.0 and there is no way it will be ready in 50days but then again I have never had one ready in 60days even under hid.

Its all I got mate. I know lukio is doing well, just been on his actually. I'm hoping some of the folks that have used them over the water can throw a few of their grows at me.

I have been looking, honest to god. But with the QB main thread being 150 pages it took me some time to get through reading a portion of that.

I did find a QB only diary by @NapalmD that was impressive, first time I got to see some nice thick buds from QB's, waiting to see if the diary gets a weight in, but it looks bloody good.

If I was only needing 4 boards mate I wouldn't be here, I'd just get them in. :mrgreen:

Quantum boards use the same phosphor tech that's used on COBs or any other white LED.
Spectrum is pretty much the same.

Only difference is that a Samsung LM561C has 1 die per LED, while COBs have multiple die in a single package.
Since heat/light sources are spread around with a quantum board, you can get away with smaller heatsinks and you have a somewhat more even spread.

Right now the QBs are so popular because the new LM561C is super efficient and they require little heatsinking.

Advantage over HID is lower power consumption and needing less ventilation to vent off heat.

A COB grow is pretty much the same as a QB grow.
But instead of 10 100W COBs you have to picture it as 5000 0.2W COBs.

LM561Cs will probably be the most efficient thing until Cree releases their new white XP-G3s.
They've already released the new Cree XP-G3 royal blue and it's up to 81% efficient.
And even driven at 6W, it's 56,7% efficient at 85 degrees celcius.

"Using the new XP-G3 Royal Blue LED and the recently introduced XP-E High Efficiency Photo Red LED, Cree has created a new horticulture reference design that achieves a Photosynthetic Photon Flux (PPF) efficiency of up to 3.2 μmol/J at steady-state, which is over 50 percent more efficient than the traditional high pressure sodium solutions in use today. The XP-G3 Royal Blue LED delivers up to 3402 mW radiant flux, which corresponds to 13 μmol/s PPF, at its 2A maximum current and 85 C junction temperature."

@frica Cheers for the reply. To be honest I understand the tech behind them, and it has always impressed me. I cant and don't doubt the QB and COB ability to out perform HPS.

One way or another I want to out my traditional HPS setup within 6 weeks. And Quantum Boards are right at the top of the list. But there is a list.

Before I go and spend the money on anything I'd be a fool not to ask those that are already using them to show me how they're getting on. I have not seen much, but what I have seen so far has been impressive.

I don't want to compare numbers to other light sources because I personally believe there more to growing good amounts of Cannabis than having high umol. What good is 4.86 umol/j in the hands of someone that grows a low yielding strain very poorly?

But I like these QB's for a few other reasons. Safety being one of them, ease of use is another, coverage and lack of a ballast to name a few more.

I know the numbers, I know the tech, I just want to see the results some growers are getting.

@G.V the numbers and sphere testing is there on these. As pointed out a Quantum is just a diffrent Style of COB. I think what your wanting to hear is that they replace or are better than other lighting systems and that's just not easy to answer as its a loaded question. The numbers and grows are there. All you would have to do is multiply the space and lights needed.

I'll never go back to the traditional "style" of one focal light source in my grows.

As I say mate,m I know the numbers. And even if I didn't it wouldn't matter much because umol is all well and good as long as you know how to get it onto your crop.


Its experienced QB users giving a genuine opinion over HPS etc I'm after.

I have seen plenty of LED buds, and they are flavourful, but raw mass has been an issue with what I have seen. But the diary I saw here has given me a bit of confidence in that.

I understand, it's just going to take time as growers with QB's are doing the R&D. I was one of the first to get my hands on the Quantums and start growing. After many years, years ago with HID I knew what I was looking at. Outside of heat and energy one has to look at bulb changes also. My little personal 2x2.5 would need a 250w. With the QB setup I'm only 100-175w depending on growth stage. No longer have to deal with heat issues,bulb changes,energy and get better light spread.

I'm not seeing any difference in density vs HID ? I think that may have come from 3-5w diode style blurple LED lights.

the hype is real @G.V 550w of qb will replace 1000w se and 700w will replace a de
20170305_173541par 1500 qb.jpg
That is @Canopy so about 18 in from the panels in the center of a 10 x 12 area.if they didnt keep selling out in a day i would already have my op full of these things lol

Panel is hung around 6ft 6 in high. Now i do have the whole room filled with cobs but under the qb is the brightest spot on the room
