The build i'm working on will be a 4 board ( tent ) for a 36x36 . I was growing really well with one board ! .... But it was probably due to the reflective material. I was using just 50 WATTS and it was calculated to a low 5 watt per square foot of that space , which was crazy that even at that low power , my plants grew very well.
There is a grow going on by @captainmorgan ... Check it out .

I got a whole pile of mars driver seems ther'e 50V @700

they will grow nice bud, but they are horribly inefficient, and three out of four of my lights have burnt out chips. The quatum board at 100 watts puts out 3 times the light of a Mars 300, think about that... Quatum 50% efficient at 100 watts, Mars 23% efficient at 180 watts ( for the old style with 3 watt chips.) All mine are being replaced!

Hey guys,
I'm just investigating ways to add supplemental lighting to this fixture in the future. I've already drawn it up with a 2lamp t5 fixture that I could supplement with hortilux 660 and fs+uv. Also, these panels seem to fit perfectly in my cob fixture as well.
However it seems this could be overload for my 20"x46" space.
Supplemental light may not even be necessary. I just want to make sure I get the highest quality buds from the babies

that's definitely overkill. your space is less than 6.5 sq ft so you need 160-220w,
depending on how hard you want to drive your LEDs. two quantum boards would
be plenty. spend extra money on beans, quality buds come from quality genetics,
assuming your environment is proper.

My plants are well on their way. The big one is a jack herer 40 days from seed already showing calyxes and a few pistils.
The one in the middle is Humboldt Blue Dream and the far right is Barnie's critical Kush. Right now everything is under basic mars hydro 600.
I have already received my 6 Vero 29 COBs and ordered my heatsinks and drivers. I should have it built by next week and will veg these girls under a screen under the new light for a couple weeks before flipping.
I've been shooting for Valentine's Day from the get go!
Thanks for the advice, I may consider quantum boards in the future.

I'm growing in almost the same dimensions as u my cab is 22"x40"
It's lit by only one vero 29 and one quantum board for less than 180 watts and the plants are very happy
Just to give u an idea I think ur plan would be waaaay too much light

Yea I'm going to skip the boards for now and just run the 6 veros. They are only 36v so @1400 I'll be at about 300w, slightly less than 50w per sq ft and I'll have one cob perfectly centered in each sq ft.
If I do decide to add to my spectrum, I have this idea as well with hortilux t5s.
I think I will be fine without them this first go round.Attachments

What I'm seeing vs the Mars is buds all the way to the bottom. Mars only maintained the top canopy. While I think some of this is better penetration I believe its better light spread also. I see a large jump in light intensity from the walls vs without, mars never did this.

Also your style of COBs are like lasers vs the light coverage of the QB. Light to canopy may be different between the two.

I know u already have the veros I think u said
But honestly two or three quantum boards would be much more manageable heat wise in my limited experience with both
I can't get over how cool and bright they are

Quantum progress report
The little nanno 17w shop light is doing well. Started to LST
Deficiency with the soil on the left, its ok as I'm just letting these two autos do there thing for testing. The girl above will be trained to fill the whole space via scrog.
Supposed to be a short ryder but both are over 3 feet lol. Notice how far down the main cola is budding. This is 150W in a 2x2

Got Sphere data for QB304 Board 
Reports attached. I will explain the results.
We test a AZ Voltage Bin and S5 Flux bin Board. On website we have listed numbers for both AZ and A1 bin. some batches we send are AZ and some are A1.
Sphere data matches Samsung tool very closely. Read up here how to use calculator.
https://northerngrowlights.com/pages/engineering
All 3 tests were done using Meanwell HLG-80H-700A Driver
Note that thermocouple was mounted directly under the driver as that is the hottest part of the lamp. Airflow in grow tent will reduce Ths temperatures.
You may gain 0.5% - 2.0% depending on airflow in your grow space. Samsung tool can estimate that for you.
Tests were done at 120VAC
This is chart for meanwell driver we used. low power so not the most efficient
Sphere Data
Last row is your 90W kit that we sell.
DC Current is not available for last test. So lets try to look at meanwell datasheet and test reports
http://www.mouser.com/ds/2/260/HLG-80H-C-SPEC-806214.pdf
http://www.meanwell.si/datasheet/HLG-80H-C-HLG-80H-C700-RPT.PDF
Datasheet says 91.5% and test report by meanwell says 92%
Lets do both
This is the 90W kit data. Yellow indicates calculated data based on meanwell datasheet and test reports
Here is how the data compares to Samsung tool
@Stephenj37826 and I will be at Indagrow expo this weekend in Denver t HLG Booth#436 . It is a lot of planning and work
I will will not check this thread as frequently for rest of the week. I will not be able to get back to emails on time. Not accepting any pre orders.
Website will restock next week.

Just like COB LED, total system efficiency varies depending on how hard you drive the boards.
