DIY with Quantum Boards

Those aren't new tech I already seen plants grown with those PCB board LEDs, that's what mars hydro uses inside their lights and lighthouse hydro use those too, they are used in most panel LEDs....

I think you're confused with the English language.

New tech would include new technology which encoumpesses newer designed and more efficient leds. You're thinking is flawed. Your thinking doesn't accept the possibility of improving something to where it's now effective.

Leds were first developed in 1962 so these are still leds so yeah this is 1962 stuff. But if there wasn't progress then these lights wouldn't be producing the numbers they are.

If you wanna prove your point buy one and get it professionally tested yourself. Otherwise keep your poor thinking process off people's threads. You got on my thread saying some really stupid shit that doesn't make you appear intelligent at all. So stfu or show your proof or just go away. I've not seen you provide anything productive to this community other than bullshit thinking

Boards $161.5
Driver $55
L Channel $7
Misc $10
Heatsinks $50
Total= $283.5

I am working on getting the heastink piece down to $30 for 2x pre drilled anodized pcs
So soon it will be like $263.5

162.2 Lm/w System level
PPF/Watt 2.45

View attachment 3835178

$200 3070 Active cooled
View attachment 3835183

157.8lm/w at COB Level
Add driver loss 7% so 157.8*0.93= 146.75lm/w
With fan losses around 142lm/W ?
PPF/Watt 2.10

Your COB based setup is awesome too :)

I don't do the numbers game very well as I don't understand what most of it means, I built my lights based on what others posted. I'm looking to possibly be expanding my veg room by 12+ lights, I like the led strips because the spread of light is so much better as the plants get taller. The issue is each grow spot is 2x4 and a single 200$ light i build covers that easily. A florescent light at 100$ covers it too, but my lights at 180 watts cast shadows under florescent. I don't know if shadows are a scientific way to decide what light is more powerful, but I feel that plants grow "stronger" and denser under my COB light... maybe a slight amount faster.

I see no reason for my lights to be more powerful, but better PAR means I could run less power to achieve the same grow and possibly add in one more cob for better light distribution.

These boards seem like they give more usable "growing" coverage than my Mars 600 at the same wattage. I know COB setups can and do this too but in a limited height small grow tent or space these could be the ticket. My Mars 600 is very focused in the center for flowering but gets it done. If many people have had success with the older style LED lighting I can only imagine what this brings.

Just remember your Mars light doesn't put out however many watts it "claims" it is.

I know its close to 200w at the wall "why I called it a 600 and not 600W" =0)
But for that same 200W at the wall these boards can produce more useable light then I'm in !

Anything running true 200W will be better than that Mars panel.

Might I make a suggestion though that would be cheaper for you............

Hack your mars light bro and fit it with COB's will be a cheap and easy way to get into the LED's and see how you like or don't like them. You can get citizen COB's for like $12 a piece.

I wonder if I could just replace the LED panel in my Mars with a Quantum board ? I wonder if the driver inside would work ? Mount it on a aluminum panel to fit inside the case and have everything there "fans, wiring plugs ? ?"
 
Im interested to understand why these are a more even spread of light than the COB approach, yet on the PAR map the numbers still fall away dramatically at the edges, meaning they are not a even spread of light, I like the look of these but not sure why the PAR is not more even? Im thinking these will definitely benefit from secondary optics

This is day 4 of week 4 of flower 4400w. Those PCB's would go well with my new clone machines I'm making. Would be a perfect clone kit

But I'm doing a larger grow area now so those boards would be good for small tents just my opinion. I haven't even given it any thought about those PCB's because I'm waiting for the new Cree and things will change once again.

These are designed around Ledil optics @robincnn posted above. Yes they benefit from them tremendously. They are pretty dang efficient optics too. We've really fine or homework on these and once I do a par chart with a couple 3 board long bars everyone will know exactly how these boards and optics perform.
 
I tried one of these in my veg tent not too long ago:
data


... had ZERO lumen output and slowed growth to a crawl. Granted there weren't many options when I tried this and the spectrum's a bit off as well. Regardless, I'm glad Robin's pushing the envelope and I do think anything led tech warrants exploring further.

If Robin ever wants to sell those proto fixtures, I'd sure as hell buy them!

These diodes are called Mid power diodes. They use to be expensive and not as efficient. That is why cob took over the high power LED scene.
Things are changing now. Mid power is efficient, cost effective, the heat is more spread out.

Just like we have Junk cobs and quality Cree/Citizen/Bridgelux cobs
Similarly there are junk mid power LED and quality Lumiled/Samsung Mid power LED.
I think Mid power is going to take over. re-flow soldering of MID power is a challenge that we have already resolved with DIY QB304 boards.
The only thing holding back is the optics complication with mid power, which is not critical for every grow space situation.
Limited optics are available but not as easy to install. Steve and I are working hard and will resolve this challenge soon.

@Stephenj37826 is doing custom builds with these boards using 1/8" flat plates and they holding up almost as good as heatsink USA.
IM or email for details. Anodized DIY predrilled heatsinks are on order and will be available soon for $15 or under in 2 weeks

The board design i made was for a 3.3 sqft space. It is not going to provide even coverage in 2x2.5.... unless we raise the lamp from 12" to 15" or 18"

The design below will give more even spread in 2x2.5

I can't wait to get my mitts on some!

I'm really excited about their potential and if we're right we could change the game in a big way.
