DIY with Quantum Boards

We need some pics of flowering plants today and tomatoes will not cut it. This idle chatter bores me. I want QB board pics over flowering plants. :wink:

Lol, just went in there checking on things and didn't bring my camera. Leaves are staggering with nice young buds. I've been trying to Doctor one of my plants though as the FFOF was off. One other thing I noticed is that the bottom fan leaves are facing the sides of my tent and nicely taco shaped telling me two things. One the light penetration and spread is amazing bouncing off the tent walls. I'm sold on what I'm seeing so far. Jury still out on a complete flower harvest but have no doubt it will do the due.

With the 320-1400, NGL engineering page shows a 2 parallel + 2 series (2p+2s). Can this be furthered to 3 parallel + 2 series (3p+2s)? If I understand correctly the Vf is the same just the current is in thirds instead of halfed.
If correct, the 4 qb's (2p+2s) would be @ .7a, so 6 qb's (3p+2s) would be @ .466a, roughly 48w a board?

yes you can do this too
466mA correct
Yes close to 48W-50W per board. Will be more if driver pushes more than 1400mA

1. If someone does DIY with the board and the pads, coming back into stock, will you be selling drivers/ballasts or do you recommend someone?

No plans to stock drivers as there are so many options. We can consider stocking 1 or 2 drivers if they are popular.
Currently on website you can click on the driver and it takes to you find chips website with a list of where you can buy the drivers.

well my board did run 110.1V @ 700ma so wondering what the upper end of voltage they need.
here's what i am thinking that my board is a voltage hog so it run more V cause at 130v *1.400ma gives me 182 watt and with driver loss.
silly ? how do i work out it's lumen per/watt now.
Click to expand...
if it is 110.1V @700mA then it should be around 115.9V @ 1400mA
Your driver seems to be running at 1440mA assuming 92% driver efficiency and 182 watts at wall.
Voltage around 116.28
116.28*1.44= 167.44
167.44/0.92=182
Too much math for Sunday morning o_O

so now it says max is 1400ma when i am pretty sure it said 1600ma before.
ok sorry so whats the max Ma and voltage for these boards hoping right now that i am not pushing it too hard
edit and when you mean the A version give more power as in milla amps
i guess it would have to be wouldnt it ?

We did the calculation few pages back. The max driver current for board is 1600mA
Although @Stephenj37826 and i have tested boards up to 2100mA. I do not recommend it for any long term use/growing.
I updated the website to 1400mA as i assumed that is the closest match to 1600mA. However 1400mA seems a concern as meanwell 1400mA drivers push a little more than 1400mA
I will go ahead and update the website back to 1600mA to avoid confusion.
Edit: website days 1600mA already. Nothing to update
 
Boards shipped have a Vf number on them.
boards with number around 107 are AY Voltage bin.
boards with number around 110 are A1 Voltage bin.
Website will be updated to include Vf and lm/w for both my the end of the day today.

Original Heatsink (side view) SLATE 1
1.85Kg/Meter density
100+ pcs of 'slate 1' expected to be air shipped to us next week so will stock in 10-14 days.
60+ pcs of old 'slate 1' heatsinks in sea shipment expected to arrive in 4 weeks
HS-B304-1-1_large.png


New Heatsink (side view) SLATE 2
2.4Kg/Meter density. Taller and serrated fins for boards running at higher power.
New heatsink will be ready in 10 days. should be in stock end of this month.
View attachment 3870411

Hole patterns will be same for both as board size is same.

New 3X Board heastink using same extrusion as SLATE 1, just longer. SLATE xx
Limited samples of new heatsink . same extrusion as 'slate 1', just 3 times longer to fit 3 boards on single heatsink. 10-14 days.

What will the slate(xx) price be?
